Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.

On an airplane trip, learners have an opportunity to investigate the properties of air pressure at different altitudes.

In this activity, learners create air cannons out of everyday materials. Learners use their air cannons to investigate air as a force and air pressure.

Experiment with force and pressure by building a balloon rocket. When launched, the balloon will run a track wherever you place the string.
