In this activity, learners use an old CD to construct a spectroscope, a device that separates light into its component colors.

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

In this activity, learners use pop-beads to understand the characteristics and properties of polymer chains.

In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.

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 make their own heat waves in an aquarium.

This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.

In this optics activity, learners discover how they can make glass objects "disappear." Learners submerge glass objects like stirring rods into a beaker of Wesson™ oil to explore how the principles of

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.

With a laser pointer and some household items, learners can create their own laser light show. They can explore diffuse reflection, refraction and diffraction.
