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

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 a 1:140 "scale model" of NASA's X-33 Reusable Launch Vehicle (RLV) Technology Demonstrator, and investigate how the model dimensions compare to the real vehicle.

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 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.

In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

In this activity, learners construct a rocket powered by the pressure generated from an effervescing antacid tablet reacting with water, and build a launch pad for their rocket.

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

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

In this activity, learners work in teams to construct and test fly drinking straw rockets. Learners explore how changing the rockets' fins affect flight distance.

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 activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

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

In this activity, learners work in teams build and launch rubberband-powered foam rockets.

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

Using recycled materials, learners will design a transportation vehicle to carry an egg in an egg toss (a rudimentary model of a shock absorbent transport vessel).

In this activity, learners will create a model rocket out of an inflated balloon attached to a straw on a taught string.

Experiment with force and pressure by building a balloon rocket. When launched, the balloon will run a track wherever you place the string.
