In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

In this activity, learners observe color mixing and absorbency using colored tissue paper and spray bottles.

In this technology activity, learners build simple circuits, design soft circuits using conductive thread, and then sew switch-activated circuits.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.
