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.

This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan

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

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

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

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

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

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.
