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 investigate stress and strain by designing, building, and testing beams made from polymer clay.

In this activity, learners are challenged to design a wind-powered car using only a handful of household materials.

In this activity, learners will test the strength of different brands of paper towels.

In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.

In this activity, learners will use household items to design and build an elevator that will carry 2 passengers to a height of 16 inches...or higher!

In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.

Using simple materials from around the house and recycled materials, learners will engineer a grabber device to pick up and put down objects that are at least 12 inches away.

In this activity, learners explore the engineering design process and the basic mechanics behind building bridges as they build one themselves using gumdrops and toothpicks.

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

In this activity, learners are challenged to design and construct a windmill to harness the power of wind.

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

In this activity, learners are challenged to create a parachute using easily sourced materials in order to transport a LEGO figure safely to the ground.

In this activity, learners construct hail-proof houses using recycled materials to discuss storm readiness and safety.

In this genetics activity, learners extract DNA from an onion, using detergent solution, a food processor, and rubbing alcohol. They will also discuss genetic engineering of plants.

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 use a variety of household and/or natural objects to design a sculpture that balances from a single point.

In this activity, learners are challenged to build a bird feeder using recycled materials from home and are encouraged to problem solve during the extensions.

Make a model city happier with LEDs, circuits, motors, and batteries! Groups can think, discuss, design, and build what would make a community happy. Kids can work as part of a team or on their own.

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