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

In this art meets science activity, learners pack silver, ball-shaped ornaments in a single layer in a box to create an array of spherical reflectors.

In this demonstration, learners investigate mass, gravity, and acceleration by dropping a wooden bar with a balloon attached to its underside, a mass suspended from it by rubber bands, and a sharp-poi

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

In this activity, learners discover that our hands are not reliable thermometers.

In this activity about afterimages, learners explore what happens when receptor cells called cones in your eye's retina get tired.

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

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

In this activity about chemistry and electricity, learners form a battery by placing their hands onto plates of different metals.

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

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

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, learners create a large film of soap and experiment with what can and cannot pass through it.

In this activity, learners discover that it's difficult to distinguish between two different shades of gray when they aren't separated by a boundary.

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.

In this demonstration, amaze learners by performing simple tricks using mirrors. These tricks take advantage of how a mirror can reflect your right side so it appears to be your left side.

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.

In this activity about depth perception, learners create an optical illusion in a shoe box.

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