In this activity, learners explore what happens when polarized white light passes through a sugar solution.

In this activity, learners set up a night time insect observation station with a light and sheet.

A magic lantern is a light that projects an image onto a screen.

In this optics activity, learners explore why the sky is blue and the sunset is red, using a simple setup comprising a transparent plastic box, water, and powdered milk.

This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.

In this STEAM activity, learners create a "pixel tube" to explore reflections of light and color mixing.

In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.

In this activity, learners make a photographic image—without a camera!

In this activity, learners make their own heat waves in an aquarium.
