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

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.

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

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

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.

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

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