Like water drops in falling rain, a CD separates white light into all the colors that make it up.

Learners demonstrate how water can distort, refract and magnify light.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

In this activity, learners mix several sugar solutions to investigate the property of density. Each sugar solution has a different density and color of the rainbow.

In this activity, learners explore the concept of density by pouring 5 different liquids into a jar. Food coloring is added if needed to give each liquid a distinct color.

In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.
