This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.

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

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.

This activity teaches combustion as the interaction of a fuel source and oxygen.
