In this activity, learners with explore the gases present in air. They will then build their own wind cannons and challenge family and friends to a friendly competition.

In this activity, learners will observe how air interacts with a paper helicopter. Learners will test different variables of weight, size, and shape.

In this three-part activity, learners use paper to explore Bernoulli's Principle — fast-moving air has lower pressure than non-moving air.

Learners experiment with a 2-liter plastic bottle containing water and four “divers." The divers consist of open, transparent containers with the opening points downward.

In this activity (on page 2 of the PDF under GPS: Luge Activity), learners will construct a model hovercraft out of an empty spool and a piece of cardboard.

Using paper, paper clips, an index card, and tape, teams of learners design flying devices to (1) stay in the air as long as possible and (2) land as close as possible to a given target.

Learners follow the template to build and fly a paper helicopter.

Learners cut and fold a paper helicopter from the template in this PDF. They practice twirling the helicopter and observe what happens as they modify their tries.

In this activity, learners investigate how changing the center of gravity of a balloon affects how it travels. Learners fill a balloon with a little bit of water and insert into an empty balloon.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.
