Science class for fourth grade students has been all about types of energy these days. Here they are seen exploring light energy and the fact that white light is a combination of all colors of light. They used water droplets to create a prism in order to observe all the colors. After examining different sized water droplets, the students concluded that smaller droplets resulted in better rainbows. If you have or know a fourth grader, be sure to ask them to tell you all about it!
