How to make a rainbow By Yvette

This is my presentation on ow to create a rainbow. This Monday, a lady called Sally from water care came to talk to room 5 about the sewage plant and sewage pipes. sally taught us a lot about sewage water and how they turn it in to clean water. After sally talked to us about water care we did a little experiment with 4 plastic cups, 3 plastic spoons, 4 plastic tubes, 3 squirters, food colouring, salt and water. With just using those utensils we made rainbows. In my presentation you will be able to make your own rainbow. I hope you enjoy.
