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

In this chemistry lab activity, learners model the colors of fireworks by burning metallic solutions in a flame and observing the different colors produced.

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

In this physical sciences activity, learners use science to solve a "crime." Learners collect trace evidence (glitter) and explore its characteristics, such as color, size, shape, and light reflection

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.

In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color.

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.
