Creating Rainbows in Room 123

Third grade students in room 123 learned how rainbows are made. Students learned that rainbows are made when sunlight strikes water droplets in front of a person at a 42 degree angle. A rainbow is formed when white sunlight passes through water droplets in the sky acting like prisms. When we see sunlight shining on a bunch of water droplets, we see a rainbow. Isaac Newton proved that white sunlight is actually a combination of all the colors of a rainbow. You can find rainbows under waterfalls or even in the spray from a sprinkler! As an extension, students practiced creating their own rainbows at home using tools such as CD’s, flashlights, prisms, dish soap and water to find and create a rainbow!
