Rainbow science

I took the kids to the science center when we were in Florida and there was this really neat book that had some simple but fun experiments to do with the kids.

So in the Florida sunshine we tried it.

Materials:

Glass of water (filled 3/4)

White sheet of paper

Bright shining sun outside

Hold the glass of water up so the sun is shining through it, then placed the white paper in front of it and move the paper to an angel. Then you will see the rainbow on the paper. The kids were amazed. Have to admit I even thought it was really neat.

Jake and Cate are too young to understand why it happens, but for older kids you can explain that the rainbows form when the light is refracts when it passes through the glass of water. It happens just like real rainbows form when the sunlight refracts through raindrops.
