In this activity, learners build a slide whistle using PVC pipe, bamboo skewer, and piece of foam. Construction of the instrument is relatively simple.

In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook

Learners complete two simple experiments to prove the existence of air and air pressure which surround us.

This highly visual model demonstrates the atomic theory of matter which states that a gas is made up of tiny particles of atoms that are in constant motion, smashing into each other.

In this physics activity (page 3 of the PDF), learners will see firsthand that air takes up space and has pressure by attempting to inflate a balloon inside of a bottle.

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.

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

In this activity, learners explore two properties of gases: gases take up space and exert pressure. Learners assemble two flasks and a beaker, connecting them with stoppers and tubing.

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

In this activity, learners explore how a hydraulic pump works. Learners work in teams to design and build a unique water fountain that employs a hydraulic pump.

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.

In this activity, learners construct and launch rockets using simple materials and their understanding of chemical reactions.

In this chemistry activity, learners explore chemical reactions and their effects, including the kind of reaction in the human body that makes people burp!

In this activity, learners complete simple exercises to investigate the relationship between force, area and pressure and their effects on materials.

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 activity, learners explore how engineers work to solve the challenges of a society, such as delivering safe drinking water.

In this activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

In this activity, learners explore rocketry and the principals of space flight.
