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

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.

Learners construct and launch paper helicopters.

In this activity, learners build water-propelled engines from soft drink cans.

In this activity, learners explore the concept of how aerospace engineering has impacted sports, specifically exploring the design of golf balls.

Students design and build their own parachutes in this hands-on engineering project.

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

In this two part activity, learners work in pairs or individually to discover how vectoring the thrust from a jet engine affects movement of an airplane.

In this engineering challenge, learners design and build a crane out of cardboard to see how heavy a load it can lift.

In this design challenge activity, learners modify a cup so it can carry a marble down a zip line and also drop it onto a target.

In this demonstration/activity, water streaming through holes in the bottom of a suspended soda pop can causes the can to rotate.

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 explore the design of rubber band powered cars. Learners work in teams of "engineers" to design and build their own rubber band cars out of everyday items.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

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

Learners set up books with rubber bands stretched between the books. When two identical books are stretched apart and released, they move back toward each other an equal distance.

Learners construct a rocket from a balloon propelled along a guide string.

Learners build simple catapults and use them to launch cotton balls.

Learners engage in close observation of falling objects. They determine it is the amount of air resistance, not the weight of an object, which determines how quickly an object falls.

Learners examine collisions between two skateboards carrying different masses. They learn about conservation of momentum in collisions.
