Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

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.

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

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

In this optics activity, learners discover that not all shadows are black. Learners explore human color perception by using colored lights to make additive color mixtures.

In this activity about light and perception, learners create pictures in thin air.

In this activity, learners explore the invisible infrared radiation from an electric heater.

In this optics/mathematics activity, learners use two hinged mirrors to create a kaleidoscope that shows multiple images of an object.

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

In this optics activity, learners examine how polarized light can reveal stress patterns in clear plastic.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

Learners use two mirrors to explore how images of images of images can repeat forever.

In this activity about light and perception, learners discover how a flash of light can create a lingering image called an "afterimage" on the retina of the eye.

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

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

This is an activity (located on page 3 of the PDF under Butterfly Wings Activity) about how visible light is affected by tiny nanoscale structures, producing iridescence on butterfly wings, soap bubbl
