Rainbows

By Akaela and Marlia
We’ve done plenty of experiments. One of them was to find out how we get rainbows out of light. Here’s what we did. Mrs. Hansen gave us a magnifying glass, and a prism. We went outside and used them. We held the prism, and turned it until we saw a rainbow. Then she gave us some more objects. She gave a lens and a flashlight. We used those objects in a dark room. We held the prism up to the flashlight and we saw the rainbow, then we tried the lens too. It made a rainbow too! One of the reasons why we’re seeing this rainbow is because light is made up of all the colors of the rainbow. Mrs. Hansen took some water and a mirror. It made a bigger and clearer rainbow. The reason why we’re seeing this rainbow is because, when light hits a clear object it slows down and bends. That’s what makes a rainbow. The colors in the rainbow are mixed together. The way we showed this is by making a color wheel. We put a string in the middle of it and twisted it up. Then we let go of the string in the middle. As we let go of the string we pulled out. The color wheel went in circles, and it looked all white. So the way we’re seeing the rainbow is because, when the light hits the clear object, the light slows down and bends showing the colors.
