Whether you are studying light in your current science curriculum or just want to have some hands-on fun, these 3 light science experiments are sure to be a hit. Better yet, they don’t require any special tools or equipment. Children (with the help of an adult) can conduct these experiments using materials you’re likely to have on hand!
One of Isaac Newton’s most famous experiments was done with a beam of sunlight passing through a prism to form rainbow colors on the wall. You can perform a similar experiment with a flashlight, a pocket mirror, and a shallow bowl of water.
Place the mirror in the bowl so it is at an angle of about 30 degrees to the surface of the water. Darken the room, and then shine a flashlight toward the mirror. A small spectrum of colors will appear on the ceiling.
The experiment proves that white light is composed of many different wave lengths, each belonging to a different color. The water acts as a prism, refraction beach wave length at a slightly different angle to form the colors on the ceiling.
