In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

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

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.

In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

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

In this design challenge activity, learners build a tower that’s at least 12 inches high with two or more parts that move (spin, sway, or flap) in the wind.

In this activity, learners make bridges using an oil-based modeling clay (plasticene). The instructions include discussion questions for both before and after bridge building.

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

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

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

In this design challenge activity, learners build a tower that can support a tennis ball at least 18 inches off the ground while withstanding the wind from a fan.

In this Bob the Builder(TM)-themed activity, learners explore what it means to work together as a team.

Learners will build and experiment with their own windmills made from simple household materials.

In this activity, learners explore how the shapes, sizes, and distances of land masses appear differently on two different models of Earth: an icosahedron and a flat map.

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

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

In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.

In this activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.
