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 "Exploring the Solar System: Stomp Rockets," participants learn about how some rockets carry science tools—not scientists—into space, and how a special kind of rocket called "sounding rockets" can

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

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