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

This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.

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 activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

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 related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.

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.
