CD Air Puck
Source Institutions
In this activity, learners will use a compact disc to build an air puck that can glide across a smooth tabletop. The puck glides with almost no friction on a cushion of air escaping from a balloon.

Gas Model
Source Institutions
This highly visual model demonstrates the atomic theory of matter which states that a gas is made up of tiny particles of atoms that are in constant motion, smashing into each other.

Vortex
Source Institutions
In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.
