Learners make a skydiver and parachute contraption and launch it. They see that the drag created by air resistance slows the descent of skydivers as they travel back to Earth.

Learners construct and launch paper helicopters.

In this tabletop board game, players will represent a team of scientists and engineers sending a spacecraft on a mission to space.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this activity, learners design and build a Zoom-a-rang using everyday materials. Experiment with different materials and Zoom-a-rang designs to see how they fly.

In this activity, learners explore motion and airflow by setting two aluminum cans on their side and blowing air in-between them.

If you have lights, cardboard, scissors, and some brass fasteners, you can make shadow puppets! Create a story-telling and design challenge for your learners with this simple and creative activity.

In this activity, learners will design a seed and test how it travels. Learners will use the Engineering Design Process to create a seed which can move from place to place.

To learn how friction affects motion, learners build a measurement tool from a rubber band and other simple materials.

Learners explore the concepts of equilibrium and center of mass by seeing how non-symmetrical objects balance.

Learners build a simple hovercraft using air from a balloon to levitate a craft made from a compact disc (CD).

Learners construct a rocket from a balloon propelled along a guide string.

Learners build at least two different spinners (tops) to investigate how mass distribution, size, and shape affect the length of time the spinner spins.

In this activity, learners determine whether thermal energy can be used for work.

What's a more compelling problem to solve than being stranded on a deserted island?

If you have 3-foot dowels and rubber bands, you can can started on this fun and open design challenge. You can make structures big and small: make it so you can fit your parent into it!

In this activity, groups cut out and sort cards showing items recovered from a crash landing on the Moon. The 12 items range from food and water to rope and matches to a self-inflating life raft.

This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.
