In this activity (on page 2 of PDF under GPS: Roller Coaster Design Activity), learners will use food cans of many different properties (sizes, shapes, and weights) and set two cans on their sides at

In this design challenge activity, learners use a balloon and other simple materials to design an air-powered rocket that can hit a distant target.

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

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

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 motion, energy, and electricity by constructing bottle cars that run on motors.

In this activity, learners explore the properties of paper by constructing and modifying paper airplanes.

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 explore how boats are engineered to achieve speed.

In this activity, learners build an old-fashioned paddle boat out of simple materials.

In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

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

In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.

Learners create a small explosion by collecting hydrogen and oxygen gas together and squeezing them into a flame.

In this activity, learners string a line across the room and build cable cars that can move from on end to the other.

This activity teaches combustion as the interaction of a fuel source and oxygen.

In this activity related to flight, learners build a tiny stream channel to investigate how fluids (air and water) change speed as they flow between and around objects.

In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.

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

Build a car that runs on air. Using household materials, experiment with the power of air to create thrust powerful enough to move a homemade car.
