In this activity about chemistry and electricity, learners form a battery by placing their hands onto plates of different metals.

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

In this optics activity, learners discover that not all shadows are black. Learners explore human color perception by using colored lights to make additive color mixtures.

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

Water treatment on a large scale enables the supply of clean drinking water to communities.

In this activity, learners investigate vitamin C.

In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.

In this chemistry activity, learners will learn how to make their own pH indicator using cabbage leaves, and then test common household items with their homemade indicator.

In this hands-on art activity, learners will study and identify features of the external anatomy of a fish.

In this outdoor activity, learners explore how a surprising number of animals use human-made litter, such as cans and crumpled paper, to find food and shelter in their environment.

In this activity (page 12), learners apply the concepts of pixilation and pointillism to the world of biomedical science.

In this outdoor activity, learners first explore lizard feeding behavior by creating a "lizard rig" to dangle different objects in front of live lizards and see which objects the lizards try to bite.

In this activity, learners make balloon models of disease-causing bacteria.

In this activity, learners will explore nature by creating food for birds. Learners will develop fine motor skills and engage in nature observation through this activity.
