What is light and where does it come from?

In this lesson, we are going to be learning about light. We are going to learn about what light is, where it comes from and how shadows are formed. We are going to complete an investigation into how light behaves with transparent, translucent and opaque objects. You will need a piece of paper and a pencil for this lesson. If you would like to take part in the practical investigation you will need: a light source (e.g. lamp, torch or phone light), a piece of paper, a piece of cardboard and a piece of something transparent (e.g. clear plastic). If you do not have these items you can still complete the lesson by watching the teacher’s demonstration.

What is refraction and how can we use it?

In this lesson, we will learn what happens when light travels through two transparent materials. We're going to learn what refraction is, how we can use it and we will carry out an investigation to show that refraction is occuring. For this lesson you will need a piece of paper and a pencil. If you would like to take part in the demonstration you will need a piece of plain paper and a transparent glass of water. If you don't have these things then don't worry! You can still complete the lesson and watch the teacher's demonstration.

How do we see light?

In this lesson, we will learn the steps that take place when we see an object. We will draw diagrams to show how we see; we will learn the different parts and functions of the human eye; and we will learn why people wear glasses and sunglasses. In this lesson you will need a piece of paper, a pencil and a ruler.

Where do different colours come from?

In this lesson, we will be learning how we can see different colours. We will apply our learning of reflection and refraction from previous lessons to understand how rainbows are made. At the end of the lesson there will be a chance to try creating your own rainbow by refracting light! You will need a piece of paper and a pencil for this lesson. If you would like to try making your own rainbow then you will also need a transparent glass of water or an old CD. You can still take part in the lesson if you do not have these items.
