This activity (on page 2 of the PDF under SciGirls Activity: Hovercraft) is a full inquiry investigation into hovercraft engineering and design optimization.

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.

This activity (located on page 3 of the PDF under GPS: Garbology Activity) is a full inquiry investigation into design optimization using recycled materials.

In this activity, learners explore the function and engineering of dams and how dams have many uses and solve many problems in the world.

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

In this activity, learners work in pairs to conduct a series of experiments using a balloon, drinking straw, and paper.

Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

This activity (on page 2 of the PDF under SciGirls Activity: Luge) is a full inquiry-based challenge related to motion and design optimization.

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.

Learners place water and part of an antacid tablet in a film canister. The reaction creates a gas reaction that launches the film canister like a rocket.

In this physics activity, learners will explore buoyancy.

In this inquiry-based activity, learners investigate the basic forces of flight as they construct their own paper glider that represents a rainforest creature from Borneo (large, tropical island in So

In this activity, learners explore the unique challenges in transportation engineering, such as devising a method for skiers or hikers to get to the top of a mountain.

In this engineering activity, challenge learners to design a car using only 3 straws, 4 Lifesavers™, 1 piece of paper, 2 paper clips, tape, and scissors.

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

Learners act as engineers and design mini submarines that move in the water like real submarines.

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

In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.

In this activity, learners explore how engineers design tire treads to increase safety and reliability.

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.
