In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.

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 explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

In this activity, learners construct a simple air pressure launcher for paper rockets.

Hooray! In this design challenge activity, learners invent a device that launches a spoonful of confetti into the air. Learners are encouraged to create the biggest cloud of confetti possible.

This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.

In this activity, learners will build a stomp-powered launcher to blast off paper rockets they design. Materials can be found at a local hardware store or you may already have them at home.

In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.

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