If Hot Air Rises, Why is it Cold in the Mountains?
Source Institutions
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

Feeling Pressured
Source Institutions
In this activity, learners (at least three) work together to explore the effects of atmospheric pressure.

Air Pressure and Dent Pullers
Source Institutions
In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

Falling Feather
Source Institutions
In this physics activity, learners recreate Galileo's famous experiment, in which he dropped a heavy weight and a light weight from the top of the Leaning Tower of Pisa to show that both weights fall

Tired Weight
Source Institutions
Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.

Marshmallow Puff Tube
Source Institutions
In this demonstration/activity, learners observe as a regular size marshmallow is blown through a tube made from a manila file folder.

"Boyle-ing" Water
Source Institutions
In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.

On the Fringe (formerly Bridge Light)
Source Institutions
In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.

Float Your Boat
Source Institutions
In this physics activity, learners will explore buoyancy.
