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.

This is written as a display, but can easily be adapted to a hands-on activity. Learners observe and shake containers of shiny liquids.

In this activity, learners set up a night time insect observation station with a light and sheet.

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

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

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 light can refract or break apart into different colors.

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, learners explore color, light and shadow by creating their own puppets to hold in front of a light source.
