In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

In this hands-on activity, children create their own kites that can fly indoors. Learners are exposed to basic concepts of gravity and air resistance.

In this activity, learners mix ingredients in a plastic bag, and then identify three characteristics of a chemical reaction: production of heat, color change, and production of a gas.

In this activity, learners make self-assembled polymer spheres.
