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

In this activity about light and refraction, learners make a lens and magnifying glass by filling a bowl with water.

In this activity, learners test the Law of Reflection based on experimental evidence. Learners produce raw data and explanations based on their data: pencil tracings of incident and reflection rays.

In this sunny day activity, learners compare how a cup of water and a cup of tonic water reflect or refract light in the sun.

In this activity, learners make optical fibers out of strips of gelatin.

In this activity, learners make prisms from gelatin. Learners then shine light through the prisms and discover what happens. This activity introduces learners to the idea of refraction.
