In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

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.

In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

This activity (on page 2 of the PDF under SciGirls Activity: Kites) is a full inquiry investigation into how a kite’s shape affects its performance.

In this engineering design challenge, learners build an air-powered spinning machine.

In this activity, learners will engineer three different parachutes to test how well each one works.

In this activity, learners construct paper airplanes that twist and turn.

In this engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.

Learners make a skydiver and parachute contraption and launch it. They see that the drag created by air resistance slows the descent of skydivers as they travel back to Earth.

This is a great activity for investigating the basics of lift and drag as they pertain to flight. Learners will discover how to avoid "taking a nosedive" by building their own paper airplane.

Investigate how force and thrust work to propel rockets into outer space. Build a rocket: a blown-up balloon taped to a drinking straw threaded through some string.

In this activity, learners make film canister rocket ships. A fin pattern is glued onto the outside of the canister, and fuel (water and half an antacid tablet) is mixed inside the canister.

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.

The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

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 related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

In "Exploring the Solar System: Stomp Rockets," participants learn about how some rockets carry science tools—not scientists—into space, and how a special kind of rocket called "sounding rockets" can

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

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.
