﻿Hi, everybody. How are you today? That's great to hear. My name is Miss Larham and I'm your design and technology teacher for today. I am really happy that you have opened up today's lesson and I'm super excited to get started. We've got a special job to do today, everybody. We've got a job to protect Humpty Dumpty. So shall we get started to find out what we need to do? Okay. So, today we are on lesson two of our structures unit and we are learning all about freestanding structures. Do you remember last lesson when we drew and labelled some pictures of some freestanding structures that we knew, or we could find around us? We also had a look at the shape cylinder, didn't we? That hollow shape. Because we saw some of these shapes in our freestanding structures, didn't we? Now, today we're going to be carrying on our learning all about freestanding structures. And we're going to be understanding functions of freestanding structures. So, let's see what equipment you will need for this lesson. In this lesson, you will need some paper, a pencil, and some building blocks. So you might have some DUPLO or some LEGO or you might have some wooden bricks. It'd be really great if you could pause the video now, go and collect everything you need, and then press play. Off you go. Fantastic. Welcome back and well done for collecting everything you need. I hope you managed to find some of those building blocks for me. Let's take a look at what our lesson is going to look like today. So, first, all together, we're going to do our intro quiz. Then we're going to do our star words. Then we're going to be looking at famous walls. Hmm, I wonder if you know any already. Then we're going to do our talk task. Then we're going to do some predicting. That sounds fun. And then you're going to do your independent learning. And finally, all together before you leave, we will do our exit quiz. Wooh! That sounds like a busy lesson, doesn't it? Let's get started with our intro quiz. You were amazing at my questions the last lesson and I know you're going to be just as amazing today. Are you ready? On the screen now, you can see three photographs of a special type of structure. Now, can you remember what this type of structure is called? You can see it in each of the pictures. Have a really good look for me. Have you noticed the structure that's in every single one of my photographs? Are you ready to tell me? Okay, do it now. Tell me. If you said bridges, you are amazing. Well done. In each of the pictures below me, there is a bridge and that's a special type of structure isn't it? Well done. It is time for our star words. Can you give your hands a flash like this? Well done. Remember in star words, we do my turn, your turn. So I will say it first, and then it will be your turn. And you're going to say them, these star words in your big, loud voices for me today. Are you ready for the first one? Okay, my turn. Wall, your turn. Wow, that was loud. Well done. My turn, wall. Well done. Next star word. Freestanding, your turn. Freestanding. Well done for joining in. Next one, structure. Structure. Well done, and our last one for today is pattern. Pattern. Amazing, well done for joining in, and well done for using your big, loud voices. Now we're going to cover all of our star words in our lesson today. You might have heard of some of them before and some of them you might not know, but that's okay. We will cover them all in our lesson today. Now we're going to be looking at some famous walls. Now, a wall a big, solid structure and it's usually made of stone or brick. And quite often it will shut off a space or provide a barrier. I bet you could go and put your hand on a wall right now. I'm going to put my hand on a wall, you ready? There is one behind me in my room. So our house is made of walls and our walls separate our different rooms in our house and our school, don't they? Let's have a look at some famous ones. Do you know any famous ones already? Let's take a look at some of those famous walls. You're going to give me a thumbs up if you have heard of that wall before. Ready for the first one? Super, here it is. This is the Great Wall of China. Have you heard of that before? Fantastic. I've got a tricky question for you. Where do you think the Great Wall of China is? Have a think, where do you think you would find this wall? You tell me now. There's a clue in the name, isn't there? You would find the Great Wall of China in China. Well done. Let's see the next one. This is Hadrian's Wall. Give me a thumbs up if you've heard of Hadrian's Wall before. That's okay. Now, do you think Hadrian's Wall is in the United Kingdom? Hmm. What do you think, yes or no? Is it in our country? Tell me now. Well done if you said yes. You are absolutely right. Hadrian's Wall is in the United Kingdom. It's in Northern England. Well done if you got that one right. The next wall is the Wall of Sacsayhuamán, which is not in the United Kingdom. It is in Peru. Our next wall is my favourite famous wall. It's the wall of Humpty Dumpty. And we all know about Humpty Dumpty, don't we? He had a great fall and all the King's horses and all the King's men, they just couldn't put him back together again. And remember, we're going to be helping Humpty Dumpty today. So here are all four of my famous walls. I want you to have a really good look at each of those walls for me and I want you to think, what is the same about all of these walls? So I'd like you to pause the video now, have a really good think, what is the same about all of these walls? And then press play when you've got your ideas. Off you go. Fantastic. Welcome back, everybody. I wonder what you came up with. What did you notice that is the same about all of these special famous walls? I wonder, did you notice that they are all either made of brick or stone? Mm, I noticed that too. Did you notice that all of the bricks have been layered on top of each other in a special pattern? Mm, well done for thinking of that as well. I wonder, did you notice that all of these bricks have been combined together using a special material, such as cement or dirt? Mm, I noticed that as well. Also, did you notice that they are all big and tall and strong? Well done. I wonder if you thought of any more that Miss Larham didn't think of. Well done, everybody. Now it is time for our talk task. Let me show you some more photos. Do you remember I said that all of our famous walls have either brick or stone layered on top of each other in a special pattern? Take a look at these photographs next to me here of our special brick patterns. And we're going to be talking about, what do you notice about these brick patterns? So in a moment, you're going to pause the video and you're going to have a really good look at those brick patterns for me and tell me something you notice, okay? Off you go. See you soon! Welcome back, everybody, and well done for having a think and a talk for me. I wonder, what did you notice about the brick patterns? Can you tell me one thing you noticed? Tell me now. That's amazing noticing. Well done. I heard some of you say that when you were looking at the pictures, some of the bricks went this way, so longways, and some of the bricks went this way, so we could see the short side of the bricks. So some went this way and some went that way. And you can see that on the photographs next to me down here that some of the bricks, we can see the long side and some of them, we can see the short side. Well done if you noticed that. I also had some of you say that the bricks are all in rows, in layers. So there's two bricks there and some of you said that when the next layer is put on, it goes over where those bricks join together. You can see, I could carry that on. That's a special brick pattern, isn't it? So when I put the next layer on, it goes over the middle where these two bricks meet together. Well done if you noticed that as a pattern, that's fantastic. Right, everybody, I really need your help. I need you to help my good friend, Humpty Dumpty. Now, we know Humpty Dumpty sits on a wall, doesn't he? And he had a great fall. All of the King's horses and all the King's men, they just couldn't put him back together again. Now, I was thinking about my friend, Humpty Dumpty, and I was thinking, we need to make sure that Humpty Dumpty is sat on a really strong wall, so when he's sat on there, it helps him to be more safe. Hmm, do you think you'd be able to help Humpty Dumpty build a really strong and stable wall so he doesn't have any more accidents? Do you think you can help him? Great, I'm really going to help him, too. Now, I've just told Humpty Dumpty that you are going to help him to build a strong and stable wall. And he said, "Miss Larham, before you get building that wall, you need to do some predicting. You need to do some guessing." And I said, "Humpty Dumpty, what do you want us to predict? What do you want us to have a guess at?" And he said, "I want you to look at some different brick patterns." So let me show you some. So, Humpty Dumpty has sent us two different brick patterns that he wants us to make a prediction about. The first one is called staggered joints. Have a really good look at that brick pattern for me. Is that the brick pattern we looked at a moment ago where we layered our bricks on top of each other? And on the next layer, we put a brick over where the other two meet underneath. That's called staggered joints. And the next one he wants us to look at is single file columns. And I think that's just where we put bricks on top of one another and then we make a second column like this. So we've got separate brick towers. So we've got our staggered joints where we put the brick over where the other bricks meet together and our single file columns. Now, Humpty Dumpty wants us to predict. He wants us to guess, which one of these do you think will make the strongest, most stable wall? The one that won't fall over. Hmm, let's have some time to think. So, what you're going to do now is you're going to pause the video and you're going to predict which brick pattern would make a better, stronger wall for Humpty Dumpty. And remember to say why you think your chosen pattern will be better. So, do you think staggered joints or single file columns will be the strongest, most stable wall? And remember to say why. Then press play when you're finished. See you soon. Welcome back, everybody, and well done for having a think about your prediction. Which brick pattern will be better for Humpty Dumpty, the staggered joints or the single file columns? Can you point? Point to your screen now which one you think will be better for Humpty Dumpty. Staggered or single file? Point now. Well done. I wonder if you came up with a reason why. So if you pointed to this one, why do you think this one would be stronger and better for Humpty Dumpty? If you chose this one, why do you think this would be stronger and better? I wonder what your ideas were. Now, Humpty Dumpty said to me, "Miss Larham, when everybody's made their prediction, here comes the fun part." He said, "We need to try it out. We need to test to see if our prediction was right. Which one of these is the strongest?" He says we've got to try it. So we're going to do some independent learning now. I'll show you what we're going to do and then it will be your turn. So, I have got some of my DUPLO building blocks and now we're going to test out how strong and stable each one of those brick patterns is. So I'm going to start with the single file brick pattern, so I'm going to make that with my bricks. So, remember single file is some bricks on top of each other to make a tower, and then we do the same right next door, without any gaps, so we make single file columns, okay? So that's how we make a single file brick pattern. I've got it ready. Now we need to test it out. So, we're going to test it out by pushing the wall very gently to see if any of our brick wall falls down. We don't want it to fall down. That won't be safe for Humpty Dumpty, will it? Let me give it a try. I'm going to give a little push with my hand. Oh no! I only gently pushed it and look what happened to my wall! Hmm, I've got another way that I'm going to test it. I've found myself a ball. I'm going to roll the ball at the brick wall and see if any bricks fall over. That was a disaster. Look, my brick wall has fallen when I rolled my ball at it. That's no good, is it? Let's test the next one. So, I have reset my bricks, and this time I'm going to do my staggered joint brick pattern. So, remember, that's a row of bricks. And then, when we do the next layer, we must make sure that we put the brick on the next layer over where the other two bricks meet. So, can you see where this red and this blue brick meet together? I'm going to make sure that the green brick goes over those two. And then I can do another layer. Put that one in there. Like that. And to make it fair, I'm going to use exactly the same amount of bricks that I used before. Now, what I would do once I have built my staggered brick joints, I'm going to do the same test again, so I'm going to gently push it with my hand and I'm going to roll my ball at it and I'm going to see what happens, but I'm not going to show you. It's your turn now. Off you go, have fun. Welcome back, everybody. Well done for giving the task a go. I hope you had great fun building those brick patterns and trying to knock them down to find out the which one was the strongest. What did you find out about the staggered joints? I noticed that when I pushed it, no bricks fell off at all! That was amazing. And I noticed when I used my ball and I rolled it... Shall we try again? No bricks fell off! My ball just bounced straight back off. When I rolled the ball with the single file one, my bricks went flying off of my table. I wonder, what does that tell us? Which brick pattern is the strongest and most stable for Humpty Dumpty? What do you think? I think this one, too. The staggered one, because when I pushed it, no bricks fell off. Was your prediction correct? Did you guess that the staggered joint was going to be the strongest? Give me a thumbs up if you did. That's amazing. Great thinking everybody. Now, we're now able to help out Humpty Dumpty, aren't we? We can build him the most strongest, most stable wall to help him out, to keep him safe, can't we? And I'm going to tell Humpty Dumpty when I see him later, "Humpty Dumpty, using staggered joint will give you the strongest and the best, most stable wall you could think of. And I think he's going to be really pleased with that. Well done, everybody, for taking part in the task today. I hope you have great fun. It is time for our exit quiz. So, I have got one question for you before you leave today. Now, we've been helping a special person, haven't we, in our lesson today? Who have we been helping? What is the name of the person we helped today? Five seconds to think. Five. Can you tell me now? Well done, that's right. We helped Humpty Dumpty today, didn't we? Well done, everyone. Now, before you go, if you would like me to have a look at any of the work that you have done today, you can share your work with Oak National. If you'd like to, please ask your parent or carer to share your work on Instagram, Facebook, or Twitter, tagging @OakNational and #LearnwithOak. I look forward to seeing all of the busy learning that you have done today. Now, that is the end of our lesson and I cannot wait to see you next time. See you then, everybody. Bye!
