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

In this optics activity, learners discover basic lens-making techniques by using a tennis ball to make a lens out of ice.

This resource contains several mini-explorations using a slide projector as a light source to investigate light and the properties of images.

In this activity, learners use Jell-O to explore lenses. Learners cut Jell-O into convex and concave lens shapes and examine how light exits each lens in a darkened room.
