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.

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

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 international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

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

In this activity, learners investigate how some butterfly wings get their color.

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

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

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 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.

Why should we wear masks? Do masks work? Do some masks work better than others? Learners find out in this activity.

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

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.
