In this activity, learners create a model of a hot air balloon using tissue paper and a hairdryer. Educators can use this activity to introduce learners to density and its role in why things float.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this activity, learners use ABS pipe and an air leaf blower to make a strong shooting machine.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this activity, learners make different shapes that hold exactly one mole of gas (air).

In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.

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.

This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.

In this activity, learners explore Charles' Law in a syringe.

In this activity, learners build small indoor paper rockets, determine their flight stability, and launch them by blowing air through a drinking straw.

In this activity, learners make and test fly paper helicopters. Learners use templates to create paper helicopters and then take take turns flying them in the air.

This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.
