In this lesson, we will be introduced to what a scientist is. We will then be learning about materials and their properties.

What is a material?

﻿Hi everyone, I'm Miss Harris, and welcome to today's science lesson. What's your name? It's lovely to meet you. Now in this unit of work, we are going to be learning all about different materials. Now you might notice that behind me is a type of material. And every lesson I'm going to have a different background, and I want you to tell me right at the end of the lesson, what material you can see behind me, okay? Do you think you can do that? Great, now, we are looking at this question. What is a material? Let's find out what today's agenda is. So these are all the things we are doing today. So we're going to be looking at what is a scientist? What is a material? We're going to look at some types of materials. We're going to be identifying materials, so looking at them and telling Miss Harris what they are. And lastly, we've got our end of lesson quiz. For this lesson, you will need, an exercise book or a piece of paper, a pencil, a coloured pencil, and most importantly, your brain. If you need to go and get any of these things, pause the video and go and get them now. Great. Now these are our star words. These are the important words we're going to be saying and using this lesson, so it's important that we practise them. So we're going to start with the word at the top in white. And that word is materials. Can you say that word, materials? So it's going to be my turn and your turn. Materials. Then we're going to do this word here. Can you point to it? It says wood. What does it say? Good, plastic. Glass, paper. Metal, wool. Great job, let's do them even faster, are you ready? Glass, paper, wood, materials, metal, plastic. Wow, super fast. Now we are going to be scientists in this unit of work. Now do you know what a scientist is? So a scientist is a person who studies the earth around us, including things living or non-living. Let's do those actions together. So a scientist is a person who studies the world around us, including the living and nonliving things. But Miss Harris, what are non-living things and living things? Let's have a look. So here I've got two groups of pictures. Which pictures, which side, this side, or this side? Which side show things which are living? So you're right, the animals and the plants are the living things. And we are living things because we can breathe. We eat, we drink, we sleep, we reproduce, so that means to have babies. So these are all the things that a living thing does. Whereas on the other side, you can see some books and some pans, they are not living things. So scientists study things which are living and non-living. Here are some pictures of some scientists. And everyone can be a scientist. And you can see lots of different people conducting some experiments, take a closer look. So they've got lots of scientific equipment there that's going to help them with their experiments. Great, now for your first task, I would like you to draw a picture of yourself as a scientist. Can you pause the video and have a go at drawing a picture of yourself as a scientist? Well done, I'm sure your drawings look fantastic. Give yourself a pat on the back for working so hard already today. Now take a look here. What is a material? We're going to move on to the next part of our lesson. What is a material? Now here is a definition of what a material is. Let's follow with our finger, are you ready? Can you put your finger on the first one that says "Everything?" It begins with an eh. Everything is, are you following with your finger? Made up of materials. Each material, right down here, can be used to make lots of different things. Okay, put your hands down. Listening now, everything is made up of materials. Each material can be used to make lots of different things. So what is made up of materials? Everything. What is made up of materials? Can you say it to your screen? Everything is made up of materials. Let's pause the video. What is made up of materials? Can you say it to your screen? Let's see if you got it right. Everything is made up of materials, from your picture on the wall, to your toys and your teddies, to your clothes, the table that you might be sitting at, the chair you might be sitting on is made up of materials, your bag, your pencil, everything is made up of materials. Now we're going to look at what types of materials there are. Are you sitting comfortably, are you ready? Have a little wiggle, so you're nice and comfy. Are you ready? 'Cause your brain is going to take in lots of information. You ready? Are you sure? Great, so the first material, which I'm sure you already know, is glass. Glass is used to make lots of things that you might use every day. Glass is a hard material and it's transparent. That means if I hold up my glass here, you can see that we can see straight through it, it's transparent, it's? Good, transparent. We can see straight through it. Can you see my face through the glass? It's transparent, it's really shiny. And it's really hard. It's not squidgy, I can't change the shape of it. It's really hard and transparent. Glass is hard and transparent. Glass is? Good, did you tell your screen? Let's try again, talk to your screen. Glass is hard, glass is? And transparent, and? That means we can see through it. Great job, are you ready for the next one? Are you sure? So this one is called W, wood, great job. Have you seen wood before? You have, great. So wood is hard and opaque. Miss Harris, what does opaque mean? That's what you might be thinking. Opaque means that you cannot see through it. So I've got this little wooden box here. You can't see through this part of the wood because it's opaque, it doesn't light go through it. Apart from this hole here, but this part, the wooden part, doesn't let light go through it, because it's opaque. It's hard and opaque. Wood is hard and opaque. Wood is? Hard and O? Opaque, good. What does opaque mean? It means you can't see through it, good. Let's have a pause moment. What is the name of each of these materials? Pause the video and answer the question and press play again when you're done. What is the name of each of these materials? Great, so we have got wood and then the other side we have got glass. So we've got these two that we've done so far. Wood and glass. Great job, are you ready for the next one? Are you sure? Okay, ready. The next one is metal. Have you heard of metal before? You have, great. Now metal is hard and waterproof. That means it does not let water or liquid in. I've got an example here. I've got an aluminium can, it's a type of metal. You might recognise this because maybe you put your baked beans in here or your soup. Does the soup or the baked beans leak out of the bottom? No, because it's waterproof, it doesn't let liquids or water go through it. It holds it all inside, inside the tin. So it's hard and waterproof. So if I put something inside, it's not going to soak up all the water. So metal is hard and waterproof. Metal is? Good, it's hard and waterproof. So here's the next one. You may already know this one. It's called plastic. What's it called? Good, plastic. Now I have got some plastic here in front of me. Plastic is waterproof and flexible or bendy. Flexible and bendy mean the same thing. So here is my plastic tub. Ooh, you can't really see it. So this is my plastic tub. It had some strawberries inside of it. Have you seen one of these before? Good, now it's waterproof because it doesn't let the liquid in, it doesn't absorb the liquid. So like a sponge that absorbs liquid, doesn't it, and I can squeeze it out. Whereas that won't happen to the plastic. It's also bendy, 'cause I can squeeze it, watch. And I can bend it. Sorry, that was quite loud. And I can bend it and move it because it's flexible. Now I've squished it. Now it's a squished plastic punnet. So plastic is waterproof and bendy. Plastic is waterproof and bendy, good job. Ready for the pause point? Ready, you're going to pause the video and answer the question and press play when you're done. What is the name of each of these materials? What is the name of each of these materials? Okay, you ready for the next one? So now we have got paper, which I'm sure you're writing on at the moment. So paper is, it is not waterproof and it is opaque. So let's have a closer look. It's not waterproof, if I put water on my paper, it will absorb the water and it will be all soggy. So it is not waterproof and it's opaque. So if I put it in front of my face, you now can't see me because it's opaque. It doesn't let light through. So it is not waterproof and it's opaque. So paper is not waterproof and it's opaque. Paper is not, good, waterproof and it's opaque, great job, okay. You ready for the next one? So here we have got fabric. Now there are lots of different types of fabric and fabric is used to make clothes or blankets, lots of different things, your coat. And fabrics are often soft and they are translucent. That means sometimes you can see, it lets light through it. So it's soft and translucent. That means it lets some light through. So here I have got a type of fabric, it's called silk. You can see here it's really shiny. And it's really soft. And if I hold it up to the light, sometimes you can see through it. It lets some light through it. So here we've got a translucent piece of material and a transparent piece of material. So one that let some light through and one that lets all the light through. So fabric is soft and translucent. It's soft and? Good, pause point. What is the name of each of these materials? Pause the video to answer this question. Okay, so we've got metal and glass. Did you get that right? Give yourself a pat on the back, well done. Okay, now it's time to do some writing. So you're going to need to pick up your pencil and you are going to be writing down what material this is. So here I put the material is um, and you're going to write that whole sentence down and write what the material is, shown in the picture. Pause the video, have a go at that now. So now pick up your coloured pen or pencil. We are going to do something called ticking, ticking or fixing. That means we're going to fix what we have ticked. Are you ready? So this material is? Wood, did you get that right? Give yourself a tick. If you didn't, don't worry. Put a nice, neat line through it and write wood above it. If you need to do that, you can pause the video now. Okay, great job. Ready, this is the next one. This material is, um. Pause the video and write down what material this is here. Okay, pick up your coloured pencil. Ready to tick or fix? The material is fabric. Did you get that right? Give yourself a tick if you did, and if you didn't, don't worry, you can put a nice, neat line through it and write it above. Pause the video if you need to fix your answer. Well done. Now it's time for our observation. This is what I would like you to do now that the lesson is almost over. It's an activity that I would like you to do in your own time. How many different materials can you find? So I would like you to walk around where you live and see how many materials you can find, and if you can name them. So first pick up an object. Then say what it feels like. And lastly, identify the material. Okay, let's check again. So first, pick up the object. Then I want you to describe what it feels like. Then you're going to identify the material, so what it's made of. So it might look like this. Pick up this one. So this is a cup. It's . It's hard. It's really smooth. It's transparent, I can see through it. It's made out of glass. Okay? So that's what your observation will be this week. Okay, get ready. Now is something really exciting. Can you give me a drum roll? So take your two hands and you can bang on your lap like this , or you can do it on the table, are you ready? So we're going to do three, do it for three seconds, ready? Three, two, one. It's time for your end of lesson quiz. Did you know that's what it was going to be? So now is the end of the lesson. You can have a go at doing your end of lesson quiz. There are three questions that you need to answer. Can you see if you can get all three right? Great job. You've worked incredibly hard today and I am so impressed. But before we go, do you know what material is in my background? Can you shout it out? The material is? Wood, you're right. My background has got lots of wood. Well done today. Should we do a rainbow cheer to end our lesson? So a rainbow cheer is when you hold your hands out like this and we're going to make a rainbow using our hands. Do you think you can do that, ready? And we're going to make this noise. Can you have a go at that, ready? Great job. I'm looking forward to seeing you next time. Bye.

In this lesson, we will be learning about materials and their properties. We will be investigating different objects and identifying what material is used to make them.

What are objects made from?

﻿Hi everyone, I'm Miss Harris. Welcome to today's science lesson, where we are going to be answering this question: What are objects made from? Now, don't forget at the end of every lesson, I'm going to be asking you to identify what material is used in my background. So keep that in mind during this lesson. So let's take a look at what else we're going to be doing today. So we are going to be recapping what a material is, looking at, what is an object, looking at types of materials, identifying some materials using different objects, and then we've got our end of lesson quiz. You will need an exercise book or a piece of paper, a pencil, a coloured pencil, and most importantly, your brain. If you need to get any of these things, pause the video and go and get them now. Okay, ready for the next part. So we've got our star words, are you ready? Materials, can you say that? Materials, good. Wood, good. Plastic, glass, paper, wool, plastic. Okay, let's do it faster. Glass, paper, plastic, wood, materials, metal. Good job. Now, can you remember what a scientist is? So a scientist is a person who, let's do our actions, a person who studies the world around us, including things living and non-living. Can you remember what things are that are living and things that are not living? So here we've got two images, so we've got our group of animals and then on the other side, we've got our pots and pans and books. Which side shows living things? So you're right. The animals and the plants are the living things because they can eat, they can feed, they can drink water, they can communicate, they can reproduce, that means have babies, they are alive. Those animals are living things. Is a book alive, is it a living thing? Can it move around? No, it's not a living thing. So we scientists studied things that are living and things which are non-living. So what is the material? This is what we studied last lesson. Let's recap what that means. So, everything, can you follow with your finger? Everything is made up of materials, each material, but done it, can be used to make lots of different things. What is made up of materials? Everything is made up of materials. So materials are used to make lots of different things. So that leads me onto this question. What is an object? So an object is something that is made up of materials. Each material can be used to make lots of different things. So an object is something that is made out of a material. So here I have a cup. My cup, the cup is the object, here's the cup and I can put water in it and drink it. It's made out of glass. So the object is a cup, the material is glass. The object is a cup, good, and the material is go, go, go, glass, good job. So now, let's look at some types of materials and some different objects that are made out of them. So first, let's identify the objects. Can you look at the screen and can you say one object, which you can see here? So I can see some glasses, what can you see? So I can see some, maybe you can see some marbles or the magnifying glass or the glass slipper or the cup or the jar, good. So, what material is used to make these objects. So the material used is, can you say that? The material used is, glass, well done. So the objects are the things that you can see here, but the material is glass, what's the material? Glass, good. So let's practise. What is this object? The object is a, can you say that? The object is a, jar, good job. The object is a jar. The jar is made from glass, well done. Did you say that full sentence? The object is a jar. The jar is made from glass, well done, let's do another one. Here, we've got some more objects. Can you point to one of the objects and tell me what it is? Great job, I can see there is a wooden spoon. Can you see that? A spoon and a door, a table, some bricks and a little, almost like a doll's house. What material is used to make all of these things? I gave it away when I said what the spoon was called, wood, well done. So here, the object is a spoon, good job. The material is, wood 'cause it's made out of wood. So the object is a spoon, the spoon is made from wood, well done. Ready for our pause point. So here, you're going to pause the video and you're going to answer this question and then press play when you're ready. So what is this object and its material. So this object is a mug or a cup and it is made from glass. Okay, ready for some more. What material, sorry what object can you see here? Can you point to an object? What one can you see? I can see a bag, what can you see? Good, well done, can you see anything else? Well done, so I might say the object is a bag. Your turn, the object is a, good. What are these objects made from, what is the material? Plastic, well done. Okay, let's bring all of that knowledge together. The object is a bottle, well done. The bottle is made from plastic, well done. Okay, ready for the next one? Shake it, look, get ready, you ready? What objects can you see here? I can see some screws, some bolts. What can you see? Can you see the sword? Okay, so what are these objects made from? They are made from metal, well done. Okay, what is this object? Nice and easy, this object is a fork, well done. The fork is made from, can you say it, I didn't hear you. It's made from metal, well done. It's made from metal, okay. Now we're onto the next part of our lesson where we're going to do some writing. You are going to be identifying some materials and telling me what the object is and what it's made out of. So this is my model, this is my example of what you're going to write. So here I have a bottle and you can see the arrow is pointing to the bottle. My first sentence is identifying what the object is and what the material is. So the object is a bottle, the material is plastic. Then I'm going to, I'm going to write that sentence in my book because it's got a little pencil next to it. So I know I need to write that one down, but then my next sentence, the bottle is made from plastic. So I'm going to put that sentence that I'm writing down together, but I'm going to say it. You can see I've got some little speech bubbles here to help me, so I'm going to write down the object is a bottle, the material is plastic. Then I'm going to say the bottle is made from plastic. Okay, are you ready for your one? So, the object is a ... fill in the gap. The material is a ... Then you're going to write down the object is made from ... So you're going to write down what the object is and what the material is and then you can say it all together. Pause the video and do that now. Well done, now pick up your colour pencil. We're going to tick or fix. We're going to check our answers, are you ready? The object is a window, did you get that right? The material is glass, well done. So then I will say out loud, the window is made from glass. Did you write that down? The object is a window, the material is glass. If you didn't write that down, you can now fix your sentence by pausing the video and checking your answers with your coloured pens. You're going to write the correct answer in a coloured pen. Well done, ready for the next one. The object is a ... the material is... So you're going to write that first sentence down then you're going to tell me what the object is made from. Pause the video, have a go at that now. Look very carefully at what the arrow is pointing at. Well done, now let's check out our answers, pick up your colour pen or pencil. So the object is a table, did you get that one? The material is wood. The table is made from wood. So the object is this table, the material is wood. You can pause the video and check your answers now, otherwise you can tick it if you've got it right. Okay, now it's time for our pause point. What is this object made from? So pause the video and answer to the question and then resume when you're done. What is this, what's material is this object made from? So I have an example here for you. Here is the object, it's a tin can. It's what soup or baked beans come in. It is made from metal, what's it made from? Metal, good job. Okay, now it's time for a little bit of a challenge before we end our lesson. How many objects and materials can you identify in this picture? So here, what objects can you see? So I can see a book, what can you see? Good, a pencil and a sharpener. What is the book laying on, do you think? A table, well done. Now, can we see how many different materials you can identify? So I'd like you to pause the video and have a look for how many different materials you can see. So I might say the table is made from wood, it's your turn. Well done, let's check. So here we have got wood, which is the table and the pencil are made from wood. We then got the book, which is made from paper and then we've got the sharpener, which is made from metal, great job. Now, here is our observation for this week. This is what I want you to do in your own time. How many different objects can you find? And can you identify their materials? So you can identify what they are made of. So you're going to pick something up. So I might pick up this card that I've got. So this is a card, it is made from paper. You can have a go at doing that for your observation. So let's find out. You're going to pick up an object, You're going to identify what it is, so this is a card, and then you're going to identify what it's made from. The card is made from paper. So first, pick up the object, identify what it is, the object, and then identify the material. Now it's time for our drum roll, I'm sure you know, what's coming next. Are you ready? Drum roll Three second drum roll, ready? Three, two, one, it's time for our end of lesson quiz, woo hoo, and you can see, I put my little face there as a cartoon. It's our end of lesson quiz. There are three questions that you need to answer. Can you get them all right? Amazing, okay. Now, can you remember what I said at the start of the lesson? Can you identify what material is shown in my background? What is it? It's plastic, well done. The bricks are made from plastic, great job. You have worked so hard today, and you've learned lots of new things about objects and materials. Have a go at doing your observation after you've done your quiz. Remember, pick something up, say what it is. So it could be a shoe and then telling it, saying out loud, what it is made from. Have a great rest of your day and I will see you next time, bye.

In this lesson,  we will be learning about different properties of materials. We will be identifying different objects and describing the properties of the materials they are made from.

How can I describe an object?

﻿Hi, everyone, welcome to today's science lesson. I'm Ms. Harris, what's your name? Lovely to meet you. Should we start today's lesson off with a virtual high five. Great, so hold your hand up like this, and you go, just put a high five in the middle, ready? Three, two, one, go. Great, now we are going to be answering this question. How can I describe an object? So, so far we have learned what materials are and what objects are. And we're going to look at how we can describe them today. But don't worry, we're going to be recapping what a material is, and what an object is today. So also we are going to be doing these things. We're going to be looking at what an object is, identifying different materials, identifying the properties of materials, identifying properties of objects, and then we've got our end of lesson quiz. Now remember that every lesson I've got a different background. And at the end of the lesson, I want you to tell me what material is used in my background. Do you think you can do that? Great, now you will need an exercise book, or a piece of paper, a pencil, a coloured pen or pencil, and most importantly, you will need your brain, so you can do lots of wonderful learning. If you don't have any of these things, you can pause the video and go and get them now. Okay, well done. Now these are our Star Words. They're the really important words we're going to be saying in this lesson, you ready? So we're going to do my turn, then your turn. So you're going to say it out loud to your screen so someone can hear you. Okay, You ready? Waterproof. Smooth. Opaque, so opaque means it does not let any light through, opaque. Transparent, so transparent means it lets all the light through. So like my glass is transparent. Stretchy. Absorbent. Rough, your turn. Smooth, your turn. Good, now we're going to do them. I'll whisper, you're ready? Waterproof. Smooth. Stretchy. Now we're going to shout, absorbent. Transparent. Opaque. Great job, now let's recap what a scientists is. Scientist is a person who studies the world around us, including things living and non-living. So remember that living things are animals and plants, and we are living things, humans. But remember that non-living things are things like books, or pots and pans, or a table. So in our unit, this unit that we're doing now, Materials, we are studying non-living things. So like a cup is not a living thing. So first, let's recap. What is an object? And objects, can you follow with your finger, is something that is made out of materials. Each material can be used to make lots of different things. Okay, I'm going to read it now. So you sit comfortably. An object is something that is made out of materials. Each material can be used to make lots of different things. So remember that everything is made up of material, but an object is something that is made from a material. So my glass, my cup is made from glass. So let's look at some types of materials. So can you tell me what these objects are made from? What is the material? The material is? Glass, well done! The material here is? Wood, well done. The material shown here is P? Plastic, and the material used here is? Metal, well done. Now we are going to look at some properties of materials. Properties are what we would use to describe each material. So the properties are how we would describe a material. So first, we could describe a material's properties as being soft or hard. Soft or hard. Can you think of a material which is soft? So a fabric is soft. So my clothes are soft. They're made out of fabrics. But my wooden box, that you've seen before, is made from wood, and it's hard. Then we have got absorbent and waterproof. If something is absorbent, it soaks up the liquid into itself. So a sponge, if I put the sponge in some water, it would soak up the liquid. Whereas for waterproof, if I had a jacket and it started raining, and it stopped me from getting wet, it would be waterproof. It doesn't soak up the water. It keeps the water out. So absorbent soaks up the water, and waterproof, keeps the water out. Then we have got transparent and opaque. So here, let me show you, I've got two different materials, which you've seen before. One is transparent, one is opaque. Which one keeps all of the light out? This one, the metal, you're right. It keeps all the light out, we can't see what's inside. Where as the glass is transparent? We can see through the glass. You can see Ms. Harris's face through the glass, it's transparent. Okay. Are you ready? It's our pause point. Can you name all of these properties by looking at the pictures? So put your finger on the picture and tell me what the property is. Are you ready? You have 10 seconds, I'm going to count to 10. You ready, can you name them all? Go! Did you get them all? I counted to 10. Did you get them all? Great, let's check. So first we have soft, at the top here, and hard. Soft and hard, they are opposites. Then we've got absorbent and waterproof. It keeps the water out. So we've got absorbent and waterproof. Can you do those actions? Absorbent, waterproof. Then we've got transparent where we can see through it. So transparent. Can you go like this? And we've go opaque, so you can cover your face to stop the light coming in. Opaque, transparent, opaque. Hard. Soft. Absorbent. Waterproof. Great job at doing the actions, well done. Now let's identify some properties of different objects. So here are some objects and some materials, which are transparent? Can you identify some of these materials? So I've got some ice. That's transparent, we can see through it. Water, a plastic cup, and over the other side, we've got a glass cup, which we know is transplanted because Ms. Harris has a glass. We've been looking at it. So transparent, transparent, your turn. Good, we can see through it. Then we've got opaque. What materials can you see here? Brick, well done, what else? Wood, rock, and what's over the other side, L, L, you might not know this one. Leather, the belt is made of leather, and it's got a metal buckle on the side, on it. So these objects are made out of materials, which are opaque. So remember opaque is like this, opaque, your turn. So it means it doesn't let the light through. Okay, you ready for one more? How am I describing these materials? They are us S. Soft, good, so we've got some wool up here, which is really soft. Ms. Harris has got some wool here as well. So let's have a look at my wool. So my wool here is soft. Look it's, ooh, it's so squishy and soft. So I would describe the wool as soft. We've then got the leather here, which is also soft. We've got some cotton balls and some fabric, and a rubber at the top, which we can also describe as soft. Now here are two properties, which we haven't talked about yet. Can you think about what these might mean? So what are the properties shown him? Can you pause the video and tell your screen, and then press play when you're done. Did you check, what were they? So we have got flexible or bendy. Flexible or bendy, whichever word you want to say, and shiny. Great job, so we've got flexible and shiny. They are some new ones that we haven't heard before. So we know that Ms. Harris's tin can is shiny, look you can see how shiny it is. But it's not bendy. It's not bendy. So I am going to show you a picture of an object, and we are going to be writing down the properties off each material. So here is an example of what you are going to do. So here we have some cling film which you might use to wrap around your food to keep it nice and fresh. We are going to identify the object and the material, so here. Cling film is made from plastic. So you can see here, I'm going to say it because I've got this little icon here, the speech bubbles, I'm going to say it. Cling film is made from plastic. Then in my book, I am going to write down what the plastic is like, I'm going to describe its properties. So plastic, the material, is transparent and waterproof. It's transparent and waterproof. So first I'm going to say what the object is and what it's made out of. Then I'm going to describe the material, what it's made out of. And you can use the word map on the other side to help with your spelling of the properties. So here is your first one. Can you say what the object is? So what can you see in this picture? Towels, good, towels are made from cotton. Can you say that word? Cotton, cotton is a type of fabric. Cotton is mm and mm. So you're going to write down two words, two properties to describe cotton. Pause the video and do that now. Well done, so let's check. So cotton, you could have said, is soft. You may have said as well, that it's opaque. Or you could have said it's absorbent because we use a towel to dry ourselves, once we've had a shower or bath. And it keeps us nice and dry once we've rubbed it on our skin, it gets all the water off. Okay, here's the next one. Windows are made from what? Glass, well done. Now you're going to write down two properties to describe glass. Don't forget to use the word map on the other side. So glass is mm and mm. Write that down in your book, of you go. Well done, so glass, I might have said, is hard and opaque. Sorry, transparent. Sorry, it's not opaque. Glass is hard and transparent because we can see through it. You may have described it as waterproof as well because when it's raining and our window is closed, it doesn't let the water come in, does it? Great job. Now it's time for our observation that we've been doing every week. How many different objects can you find? And can you identify their materials? So first, pick up an object. Then you're going to say, what material is it made from. Then you're going to describe its properties. So let's recap. First, pick up a object. So I might pick up, mm? I'm going to pick, what shall Ms. Harris pick up? I'm going to pick up my straw. So I've got my straw. What is it made from, is the second one that I'm going to say? So I might say, hmm? My straw is made from metal. Then I'm going to describe it, mm. The metal is hard, and, mm, it's opaque because I can't see through it because it's really colourful. So pick up the object. My straw is made from metal, and it's hard and opaque. Can you have a go at doing that with some objects that you can find around your house? Great, are you ready for the drum roll? Ready, pick up your hands. Ready, drum roll, three seconds. You can do it on your lap or you do it on the table, ready? Three, two, one. What's it time for? Our End of Lesson Quiz, whoo-hoo. And you can see me jumping up with a little heart. It's time for the End of Lesson Quiz. How many questions do you think are in our quiz? Three, well done. Three questions are in our quiz. Can you get them all right? I'm sure you're going to try really hard. Now before we go, can you remember what I said at the start? What I want you to do, tell me what material is used in my background. What materials do you think you can see? I can see? Good, the pipes are made from metal. Great job, well done. I am so impressed as usual with your hard work. Shall we do a different cheer today? Shall I teach you a roller coaster cheer? Have you ever done one of those before? So for a roller coaster cheer you need to put your arms up like this to make your seat. Then we're going to go up, up, and up, and then we're going to go, woo, woo, woo, like we're going down a roller coaster, you read? So we're going to go. And another one, Then we're going to do three more. We're going up. and then three woos. Woo, woo-woo, woo. Great job, that's the roller coaster cheer, if you haven't done one of those before. Well done today. You have worked really hard, and I look forward to seeing you next time, bye.

In this lesson, we will be investigating different materials and their properties. We will be exploring which materials float and which materials sink, then we will be making comparisons while looking at their properties. Do all hard materials sink? Do all soft materials float? If you would like to take part in the experiment you will need a coin or small metal object, a cotton ball or pad, stones, a pencil and a bowl of water. Otherwise, you can watch me conduct the experiment while observing the outcomes.


Which materials float and sink?

In this lesson, we will be learning about absorbency. We will test and compare the absorbency of a variety of household materials. You will need a piece of paper and a pencil to complete today's lesson. For the experiment, if you would like to take part, you will need: a sponge or cloth, plastic bag or cup, foil, cardboard or paper, cotton wool or tissue. If you do not have these materials, you can watch me complete the experiment while observing the outcomes.

Which materials are absorbent?

﻿Hi everyone, I'm Miss. Harris, welcome to today's science lesson. How are you doing today? Good, I'm glad to hear it. Are you excited for today's lesson? Me too, now today we are going to be looking at this question, which materials are absorbent? We're going to find out what the word absorb means today, and we're going to be doing an experiment. Let's see what else we're doing today. We are going to be looking at properties of materials, identifying materials and properties, looking at what absorbent and waterproof mean, then we're going to be doing our absorbing experiment, and then we're going to be looking at the use of different absorbing materials. You will need an exercise book, a pencil, a coloured pencil, and your brain. If you don't have these things, you can pause the video, go and get them now. Great, so hopefully you're ready for today's lesson now. Now, if you have them, you could also find some of these materials for our experiment. So you can choose, hopefully if you've got these things, either a sponge or a cloth, a plastic bag, or a plastic cup, some tinfoil if you've got it, some cardboard or a piece of paper, some cotton wool or some tissue. So if you have any of these things and a bowl of water, today, we're going to be talking about whether we're going to investigate which materials are absorbing. So if you don't have these things, don't worry because I'm going to show you the experiment as well, so we can do it together there. Let' do our star wars we're going to practise these words, you ready? My turn, then your turn. Waterproof. Absorb. Compare. Materials. Absorbent. Absorb. Great job. Now, a scientist is what we are going to be today. A scientist is a person who studies the world around us, including the living and non-living things. So we're going to be investigating non-living things because we're going to look at materials and my pencil, my pen is not a living thing, is it? But we're going to investigate what things are made of. So let's recap some properties of materials. Here are some different properties to describe a object, to describe the material the object is made from. Can you pause the video and tell me what each of these properties are? Okay, so let's check which properties these are. So we have got soft, hard, absorbing absorbent, waterproof, transparent, opaque. Then we've got shiny, and lastly, we've got dull. So if something is dull that means it's not shiny. Okay, so it's not shiny. Great job. So let's now identify some materials and their properties. So here are two new properties that we haven't talked about before. We have got stretchy and we have got bendy. So if something is bendy we can move it around a lot and move the material around. But if something is stretchy, that means we can put really far like this. So here are some different materials which we might describe as bendy. take a look, what objects can you see here? So I can see a rubber band, I can see a scarf, what else can you see? A leather belt good, and in the middle, we have got a metal fence. Now I put the metal fence on there as well, because we know that when we have a metal, sometimes it's not bending. But if you heat up a metal, it can become bending if you move it around, but don't try that at home. Okay, here's a pause point, which material here can we describe as stretchy? So take a closer look, which material can we describe as stretchy? Okay, so which one is stretchy? The rubber band, good job, so the rubber band is stretchy. Good job. Now let's take a closer look at absorbing materials and water proof, what does it mean? So if something is the absorbent, that means that it can soak up a liquid, whereas if it got waterproof, it keeps the liquid out. So absorbent is able to soak up a liquid easily, whereas waterproof means it keeps the water out it stops you from getting wet. So Miss. Harris which materials are absorbent? That's what going to find out in today's experiment. So these are the things that you will need, either a sponge or a cloth, a plastic bag or a plastic cup, some tinfoil, some cardboard or some paper and some cotton wool or some tissue. And don't worry if you don't have these things, you can watch me do the experiment because I am going to show you shortly in this video. So if you don't have these things, don't worry, because I'm going to show you. So now is the time to pause the video, go and get these things and ask your parent or carer if you can get started on the experiment. You will need a bowl of water as well, and we are going to dip each material into the water to see if the water is soaked up by the material, or if, when we take it out, it's the same as when we put it in the water. But before we do anything, you will need to draw this table into your books. So pause the video and draw this table. So now I have drawn my table, I've included all of the objects and materials at the top that I am going to test in my experiment. I'm going to put either a tick or a cross in each row to tell me whether it is absorbent or whether it is waterproof. Well done, now let's read our method. This is our instructions of what we're going to do. First, ask your parent or carer if you can use the water to test the absorbency. Then we're going to make sure that any valuable items are far away so that we're not going to get the wet. That means our computer, or your laptop, or your tablet, or anything you're watching me on is moved away. And make sure you're in a space which you don't mind getting wet. So maybe your desk or where you're sat is not the best idea, maybe you want to do it in the kitchen or in the bathroom where you can get the floor a little bit wet. Then you're going to pour a very small amount of water onto the object. And does the material take in the water and absorb it? Or is it's waterproof, and doesn't soak in the water? Now because we're doing it like an experiment, remember that we need to stay safe. So a scientist needs some of these things to say safe. Now, today we are only using water for our experiments, so we don't need anything to protect our eyes and our hands, but you might want to wear a lab coat, maybe a white shirt or a white top that you've got in your house so that you can look like a scientist while doing your experiment. Can you help me put on my lab coat? Could you help me put on my lab coat? Great. Now to help me put some my lab coat, I'm going to need you to get your hands ready. So they are really magical. So just start the magic you can rub your hands together like this, rub them together, are you rubbing? Rub them faster, and then now they're ready. We're going to do three clicks, like this, ready? 1, 2, 3, and then my lab coat should appear by magic. So I can start the experiment. Are you ready, too, you can help me. Ready, three clicks 3, 2, 1. And just by not check my lab on. Thank you very much. Now I'm ready to start today's experiment. Don't forget to put your lab coat on 10 too. Now it's time to begin your experiment. If you have all the materials you can get started now or you can continue watching to watch me do the experiment. So I've got all my materials ready, I've got my cloth, I've got my foil, my cup, my tissue, and my cardboard. I'm going to use a jug of squash for my experiment, just so that we can see it when I pour it onto the material. So I am going to put the material onto the plate, then I'm going to pour the liquid onto the material. If there is any water left on the plate, then we know that the material is waterproof. If there is no liquid left on the plate, then we know that the material has absorbed the liquid. It has soaked up and taken in the squash. So let's start with the cloth. I'm going to pour a little bit, We can see straight away that the liquid has almost disappeared. Is there any water on the plate? Can you see the squash? No, it's has been soaked up and you can hear it. It has been soaked up by the cloth. So the cloth has absorbed the liquid. So I've just used the cloth in the experiment and we know that it was absorbent, it was not waterproof. Now let's do the plastic cup, let's pour bit of liquid on that. I can see straight away that the liquid has poured straight off of the plastic cup. Has it taken in any of the water? No, it has not. So the cup, the plastic cup is waterproof. I've just poured the liquid onto the plastic cup, so now I'm going to put either a tick or cross. Was it absorbent or was it waterproof? It was waterproof if you're right. So i get to put to the tick here, I'm going to cross because it was not absorbent. Now let's do the tinfoil, let's see if the tinfoil is waterproof. So remember if the liquid is still on the plate, then we know it's water proof. We can still see the liquid when we poured it on the cloth, it's soaked up straight away didn't it? Is the liquid being soaked up by the tinfoil? No, you can see, look it's running off the material straight away. So we can see the tinfoil is waterproof. Now we're moving on to the tinfoil. Was the tinfoil absorbent, or was it waterproof? It was waterproof, you're right put a tick here, and put a cross in the absorbent because it was not absorbent. It did not soak up any of the liquid it was left on the plate. Now let's try the cardboard. So let's see. So watching carefully. I poured a little bit, onto the cardboard. Mhh, if I tip it up, it looks wet still. So you can see that the cardboard is still wet, and if I just move it around into the liquid, does that make a difference? You can see, look, the cardboard has absorbed the liquid look, we can see now that it's squishy, it's changed colour, we can see where the squash was poured onto the liquid. And we can see that there is no liquid left on the plate so the cardboard is not waterproof. Now the cardboard. Was the cardboard absorbent, or was it waterproof? So this time it was absorbent so I'm going to put a tick here and it was not waterproof because we saw that the cardboard soaked up the liquid. And lastly, let's do the tissue, so put the tissue onto the plate, and I'm going to pour the liquid onto it to see if it absorbs any of it. So you can see straight away, the tissue has soaked up the squash, the liquid, and there is no water left on the plate so we can see here, it's soaked up the water. If I squeeze it might come out, only a little bit. So the tissue is not waterproof. Now the tissue, is tissue absorbent or is tissue waterproof? It's absorbent great, so put a tick here, it was not waterproof because it soaked up the liquid. Well done. Did you enjoy watching and or doing that experiment? Great, me too now let's check our results. So this is what your table might look like because we are ticking whether it was absorbent or we're ticking whether it was waterproof. So, the cloth or the sponge, so I used the cloth, it was absorbing, it absorbed all of the water that I poured onto it didn't it? Well, most of the water, it was not waterproof. Then we had the plastic cup, which was waterproof. Then I used some cardboard. Do you think it was waterproof? Sorry the tinfoil, was it waterproof? It was waterproof, you're right. What about the cardboard, was the cardboard waterproof? No, it soaked up some of the water didn't it? And lastly, the tissue, soaked up the water straight away, didn't it? Yeah. Now your table hopefully looks like mine. Now we've got a quick pause point. Which material was the most absorbent? So which ones soaked up the water the most? So I think that the tissue soaked up the water the most didn't it? But then it broke and it didn't last very long did it? So maybe the cloth was the most absorbent because it's soaked up the water and it wasn't breaking like the tissue did. Now, which material was the least absorbent? So which one was the most waterproof? So you could have said the cardboard or the plastic cup or the plastic bag whichever one you used, because they, both materials were not affected by the water. Now the use of these absorbent materials, we can use them in our lives so we can use them every day to help us soak up some water. The first I'd like you to think about why do you think towels need to be absorbent? Pause the video and have a think about that now. So did you have a think? Why do towels need to be absorbent? That's because when we have a shower or bath, we use the towel to get dry, to dry ourselves, and it absorbs all the water off of our body to make us dry. That's why we use towels, they need to be absorbing. Otherwise we would just be getting wet, we'd be rubbing it on us, and we wouldn't be getting any dryer. What about a sponge? What do you think? Pause the video and have a check now. So why does sponges need to be absorbent? Because we use them to soak up, lots of may be some washing up liquid when we're doing the washing up, or if we spill something, we might use a sponge to clean it up. So it soaks up the water for us and helps us with our cleaning or with our tidying up. And lastly, over two more, not lastly, two more. Why do you think wellies and umbrellas need to be waterproof? Pause the video and have a think about that now. So wellies and umbrellas need to be waterproof because otherwise we would get wet when we wore them, or if we held our umbrella up above our head, we might get wet and we use the umbrella to keep us dry, and our wellies to keep our feet dry when we jump in lots of puddles. Okay, this is the last one. Why do you think glass needs to be waterproof? Pause the video, have a think about that now. So here we can see there's glass windows on a car. If we're driving along and it starts raining, we get very wet, wouldn't we? If the glass wasn't waterproof, or if we were in our house and it started raining the water would come through the glass. so we need to make sure that the glass is waterproof. That's why we use glass on windows, so it protects us from the rain or water. Now it's time for the end of lesson quiz, where you can show off everything that you have learned today. Now before we go, can you tell me what material is in my background? So this is a tricky one today, you might not know the answer. So we've got some tyres. Do you know what tyres are made from? They're made from a material called rubber and tyres once they are made they're quite hard to get rid of, once you have a tyre, they're really hard to recycle and reuse. So tyres are made from rubber that's in my background today. Well done. You have worked super hard today, I am super impressed. Now it's time to do your quiz don't forget and have a great rest of your day and I'll see you for our next lesson. Bye.

In this lesson, we will be learning about materials and their properties. We will also learn why certain materials are used for specific purposes because of their properties.

Which material is best for different objects?

﻿Hi, everyone, welcome to today's science lesson. I'm Miss Harris. What's your name? It's lovely to meet you. Should we do a virtual high five to get started today? Ready? So we're going to high five in three, two, one, go! Great job. Now today is our last lesson of our materials unit. We are going to be looking at which materials are best for different objects. So which material is best for different objects. We'll be looking at why certain materials are used for particular things because they have a purpose. We are also going to be doing our star words, looking at properties in materials, identifying materials and their properties. Then we're going to look at using different materials for different objects, and then we've got our end of lesson quiz. Don't forget that the end of the lesson, I'm going to be asking you to tell me, what material is behind me? In this lesson, you will need an exercise book or a piece of paper, a pencil or coloured pen, and coloured pencil sorry, and the coloured pencil, and most importantly, your brain. If you need to go and get any of these things, you can pause the video and go and get them now. Well done. Now let's do our star words. So, it's going to be my turn then your turn. You ready? Waterproof, absorbent, compare, absorb, materials. Good job. So a scientist is a person who studies the, are you ready to join in the actions? The world around us, including things, living and non-living. Good job. Let's start by looking at properties of materials. Now here I've got lots of pictures of different properties that represent different properties, can you pause the video and name all of them? Let's see if you can remember. Pause the video and do that now. Great, so let's check. So let's do the action, let's see if we can remember. Soft, hard, absorbent, waterproof, transparent, opaque, shiny, dull, stretchy, bendy. So remember our elastic band is bendy, but it's also stretchy so I can bend it any way that I want, but it's also stretchy. Good job. Now, we're going to identify some materials and their properties. So first look at the picture, what is in the picture? What is the object? The object is a, crayon, well done. Do you know what crayons are made out of? So they are made out of something called wax. Now I want you to describe two properties of wax. So you're going to pause the video and look at this word mat here. Can you choose two properties to describe the wax crayons? Okay. So I might describe them as quite soft because when I write with a crayon, bits of it break off onto my paper and that's how I can draw. So they're quite soft and I would also describe them as waterproof because if I put my crayon in the water and take it back out again, I can still use it. What did you have? What properties did you think of? Well done. Great job. Let's do the next one. So what can you see here? What is the object? A wheel or a tyre well done? What's it made out of? Rubber, well done. Good job. And can you name two properties to describe rubber? So pause the video and do that now. So I might describe the tyres as being waterproof because when I drive in my car, my wheels they get wet, but the water is not soaked up by the tyre. And I might describe them as quite dull because they're not very shiny are they, not super shiny like a coin or some glass? They're quite dull. What did you describe them as? What properties did you think of? Can you tell your screen? Wow, amazing. Great job. Now it's time for our pause moment. Take a look here at the scissors and the paper, which material, the metal scissors and the paper would I describe as dull? Which material would I describe as dull? Have a think. Tell your screen and then press play when you're done. Which one did you think was quite dull? The paper you're right, because the metal on the scissors sometimes it's quite shiny isn't it? Amazing. Well done. Okay, so let's do one more of these. Here I've got some paper from a book, so there's paper from a book. How can I describe the paper? Can you choose two properties to describe the paper? So we already know that we could describe paper as being dull. Can you choose two different ones instead of using dull? So I might describe the paper as being bendy because I can move the paper and I might describe it as opaque because it keeps the light out. What did you have? What two properties did you think of? Great job. Well done. So now let's take a closer look at the use of materials for different objects. So here you can see someone is holding a bottle. I've written the sentence down here. Can you put your finger on the pink letters that say bottle? So put your finger on it? We're going to read ready. Bottle is, So the bottle, is made from plastic. It is hmmm so that, so I would write, it is, Hmm. It is transparent so that I can see what liquid is inside the bottle. Can you think of a reason why that material, why plastic is transparent? Or you might think of a different property and describe it. So why is the plastic bottle, why is it waterproof? Can you tell me why? So first think of a property to describe plastic and then can you tell me why we have that property? So you're going to do write it down in your book. So I might write it is transparent so I can see what liquid is inside. Can you have a go? Well done. So now we've got a hot water bottle. So the hot water bottle is made from rubber. Can you think of a property to describe the rubber and why do you think we have that property for it? What is the purpose of it? The need? What is the need for it to be like that? So first choose one property. So the hot water bottle is hmmm choose one here. So it is waterproof. Why is it waterproof? What do we put inside the hot water bottle? We've got hot water inside it. Why do you think then, it needs to be waterproof, if we're putting boiling hot water inside it, can you pause the video and write the sentence below? It is waterproof so that, so that it's stops the hot water from leaking out of it. So it needs to be waterproof so that it doesn't absorb the water because otherwise it might burn us might en it. It can get worm and hot the bottle, but we don't want it to spill the water. Okay. Let's do one more. The door is made from wood, it is hmmm so that, so can you think of a property to describe the door and tell me why that property's important? Why is it made that way? Pause the video and have a go at that now. Well done. So I might say the door is opaque so that you cannot see what's inside the door because I have a door on my bathroom so that no one can see me when I'm in the bathroom. Or my front door so people cannot see inside my house. Okay. Now you are going to write down what material you would use to make each of these objects. So let's take a look at one. So to make a table I would use hmmm. So you're going to write down what material you would use to make the table. And I want you to think about why you're using that material. So pause the video, have a go at that one. Well done. Now, can you have a go at this one, to make a car I would use hmmm. So what would you use to make the car? What material? well done. Let's do the next one. To make a jumper, I would use hmmm. So think carefully what material you would use and why. So would you use metal to make a jumper, pause the video and do that one now. Well done. Now we've come to the end of our lesson. So it's time for the end of lesson quiz, where you can answer the three questions to see how much you have learned this lesson. But before we go, can you tell me what material is used in my background? Can you shout it? It's called... cardboard. Well done. Cardboard is used lots, to store things and keep things safe. So maybe if you're moving house, you might pack all your things in a cardboard box, or if you order something online on the computer, it might come in a cardboard box to protect it. Well done. Now we are at the end of our unit of work called materials, if you would like to share any of your work that you have completed over the last few weeks, you can ask your parent or carer to take a picture of it, and you can post it onto Instagram, Facebook, Twitter, by tagging Oak National and the hashtag #learnwithoak. I hope you have a wonderful rest of your day, and I will see you for more science next time. Bye.
