In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

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 design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

The goal of this activity is to design the fastest sailboat or one that carries the most treasure.

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.

In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh

In this activity, learners will imagine the challenges and opportunities of asteroid mining.

In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.

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.
