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.

In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.

In this activity, learners explore how polarizing sunglasses can help diminish road glare.

In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color.

This is an activity about waves. Using marbles, paper clips and rubber bands, learners explore how waves behave.

In this activity, Frankenstein's lab is running out of electricity! Learners use fruit to help Igor find a temporary source of energy to turn on a light.

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

In this activity, learners explore the principles of magnetism by observing how various materials interact with magnets and superconductors.

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