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 occurring. 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.
