Learners mix vinegar and baking soda together in a bottle to create a chemical reaction. The reaction produces a gas, carbon dioxide, which inflates a balloon attached to the mouth of the bottle.

Build a catapult that transforms the potential energy of a twisted rubber band into kinetic energy. Experiment with design variations so that you can hit a target with a projectile.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.
