Science Exploration: A Rainbow Connection
This is an activity about light and its component colors. Learners will observe a photograph of a rainbow and make observations about what they see in the photo. Next, they will observe a rainbow spectrum and draw the rainbow using crayons. Finally, learners will observe a different rainbow photo to compare to the one seen in the classroom. This activity requires a flashlight with a bright focused beam or an overhead projector, a prism, and several photographs of a rainbow. This activity is from the Stanford Solar Center's All About the Sun: Sun and Stars activity guide for Grades 2-4 and can also accompany the Stanford Solar Center's Build Your Own Spectroscope activity.
