In this activity, learners will explore light with reflective surfaces. Learners will make predictions and share their observations as they experiment with directing a beam of light.

In this outdoor, nighttime activity, learners gather around a brightly lit, white surface and study the behavior of nocturnal animals attracted to the light, particularly night fliers.

Did you know that using a lens one can bend light to make pictures of the world? It's true!

With little more than a flashlight, a straw, and a plastic lid, make an observatory so you can see the amazing colors in bubbles.

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

In this activity, learners will explore light and rainbows with this easy setup! Learners will only need a cup of water, some paper and a flashlight.

In this activity, learners will explore how different colors of lights interact with objects around them. Will a blue object stay blue with a red filter?

In this activity, young learners will explore light and darkness through flashlight play.

This is an activity about waves. Using marbles, paper clips and rubber bands, learners explore how waves behave.

In this activity (17th on the page), learners investigate why you cannot see colors in dim light.

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

In this physics activity (page 6 of the PDF), learners will demonstrate air has weight by comparing an inflated balloon to a deflated one.

In this demonstration, adult learners create a lava lamp using beer and nuts! Use this pub-themed activity to demonstrate the effects of buoyancy and bubbles.

In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity, learners turn empty 2-liter bottles into a see-through compost container.

In this activity, learners observe color mixing and absorbency using colored tissue paper and spray bottles.

In this activity, learners investigate the effect of heat on a reaction.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.
