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.

In this activity, learners build water-propelled engines from soft drink cans.

In this engineering activity, young learners investigate multi-level buildings.

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

In this engineering activity (page 2 of PDF), young learners investigate how a wide base can make a building more stable. Learners use blocks or boxes of different sizes to construct stable towers.

In this design challenge activity, learners build a machine out of cardboard that runs smoothly and dependably. Learners must be precise to make sure their component works properly.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

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.

In this activity, learners will engineer three different parachutes to test how well each one works.

No glue is needed for learners of any age to become marshmallow architects or engineers.

In this activity, learners design and build a NASA rover using raw pasta and candy with a limited imaginary budget.

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.

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

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

In this activity, learners are challenged to design, build and test a birdhouse that will stay cool in the sun.

In this activity, learners design a therapeutic agent to image and/or cure various diseases in the respiratory system.
