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

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 physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

In this collection of demonstrations, learners explore Newton's Laws of Motion.

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

Take the two-straw challenge and discover how pressure affects vacuums! In this activity, learners experiment with drinking through one and two straws, comparing the amount of liquid they can drink.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.
