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.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

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

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 make their own heat waves in an aquarium.

In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

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 math activity related to light, learners explore why a light, such as a candle or a streetlight, looks dimmer the farther away from it we get.

In this activity, learners explore light, color and rainbows by making their own rainbow glasses.

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

In this optics activity, learners discover that when they rotate a special black and white pattern called a Benham's Disk, it produces the illusion of colored rings.
