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 meteorology activity, learners construct simple devices to measure the direction and speed of wind.

In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.

Hooray! In this design challenge activity, learners invent a device that launches a spoonful of confetti into the air. Learners are encouraged to create the biggest cloud of confetti possible.

After a discussion about what a parachute is and how it works, learners create parachutes using different materials that they think will work best.

In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.

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 sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

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.
