Maths- Add and subtract fractions- remember you need to find a common denominator. 

English- Informal to formal: Read the invitation that has been written in an informal style. Use the key vocab word bank to rewrite it in a more formal style. 

Topic- Famous scientist Isaac Newton discovered the colour spectrum. He discovered that white light is made up of all the colours of the visible spectrum. i.e. red, orange, yellow, green, blue, indigo and violet… as well as the shades in between. You are going to do an experiment to prove this. 

Watch the video to learn how to make 'Newton's disc'. https://www.youtube.com/watch?v=lil4co0z7QA

You'll need: Cardboard, paper, coloured pens, string, something sharp, scissors.

Why does this happen? Spinning the disc mixed all the different wavelengths of coloured light together, creating white light. The faster you move the disc, the more white light you see. There is a fact sheet about Newton's discovery if you want to read more.
