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

In this quick activity (page 2 of PDF under GPS: Lava Flow Activity), learners will model how large depressions near the top of a volcano are formed by using an inflating and deflating balloon submerg

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

In this physics activity (page 2 of the PDF), learners will construct their own walkalong glider. They will explore how air, though invisible, surrounds and affects other objects.

This lesson guide includes six simple and quick activities to help learners better understand Bernoulli's Principle.

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.

In this activity (located on page 2), learners will construct tiny model geysers out of film canisters, warm water, and antacid seltzer tablets.

Learners observe a flask with a balloon attached over the mouth and inverted inside the flask.

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.

In this activity (page 1 of PDF under SciGirls Activity: Forecasting), learners will construct an air cannon by cutting a hole in the bottom of a bucket and stretching a garbage bag over the other end

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