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.

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 how light can refract or break apart into different colors.

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

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

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

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

Create an illusion where it appears that your hand has a hole in it. You'll see the results from when one eye gets conflicting information.

Look at pictures through different color filters and you'll see them in a new way. People have used color filters in beautiful photography or sending secret messages.

This science activity demonstrates the dominant eye phenomena. What does your brain do when it sees two images that conflict?

Do you have a hard time matching paint swatches with your furniture? When you consider human perception, color is context dependent.

In this activity, learners explore a scale by comparing objects, which look similar but have different weights. Learners predict and then measure the weights of various objects using a scale.

This is an activity exploring color and color mixing.

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 (page 2 of PDF), learners play with a lens and a piece of paper to focus an image on the paper. Learners look at different things, and see how the lenses affect the image.
