In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

In this space science activity, learners explore transits and the conditions when a transit may be seen.

In this demonstration, learners explore a variation of a Foucault pendulum, but upside down.

In this demonstration about force and motion, learners will explore the forces that affect a pendulum A simple model pendulum comprised of a ball and string demonstrates how pendulums work as well as

The demonstration/experiment provides quick proof that air has mass.

This demonstration/activity helps learners understand why higher elevations are not always warm simply because "hot air rises." Learners use a tire pump to increase the pressure and temperature inside

In this quick activity, learners observe how wind creates ocean currents.

In this demonstration, learners observe the effects of density and pressure by attempting to make "balloon kebabs." Learners will try to insert a wooden skewer all the way through an inflated balloon

Learners develop an understanding of air pressure in two different activities.
