Lesson Plan Outline for Rainbow Science
Young scientists study light reflection and refraction as they determine the critical angle, the rainbow angle, and color separation in rainbows. Teams record the data they collect in a shared spreadsheet and discuss results with the class.
Curated OER
Light & Crystals
Students observe a demonstration of light refraction. They experiment with disappearing crystals to further study light refraction.

Geometrical Optics: Reflection and Refraction of Light
Students define and discus the concepts of wave fronts and rays. In groups, they distinguish between specular and diffuse reflections and use Snell's Law to predict the path of light rays. They calculate the speed of light through...
National Nanotechnology Infrastructure Network
Jell-O® Waveguide and Power Loss
Jell-O® can help model the transmission of light through fiber optic cables. Young scientists use the jiggly dessert to make a waveguide to transmit a laser beam from one point to another. Their models help them learn the function...
