Students design and create their own air-powered rockets, in this hands-on activity.

In this activity, learners design, build and test a model suspension bridge for sturdiness and strength.

In this project, students explore how levers work, by making a puppet with moving limbs.

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

In this design challenge, learners build a boat that paddles itself using a rubber band as its power source.

In this hands-on activity, learners use the steps of the design process to create a hook to rescue a "space capsule" from the water.

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 will build a roller coaster for a marble to run on using everyday household materials such as paper towel or toilet paper rolls, cups, boxes, books, buckets, chairs, etc.

In this activity, learners design wind-powered cars out of simple household materials. Students have fun designing and then racing their vehicles around the room.

In this design challenge activity, learners build a boat that can hold 25 pennies (or 15 one inch metal washers) for at least ten seconds before sinking.

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

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

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 dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.
