In this activity, learners explore how engineering has impacted the development of bridges over time, including innovative designs and the challenge of creating bridges that become landmarks for a cit

In this activity, learners explore how engineers have developed big wheels or Ferris wheels.

In this activity, learners create a working model of a nail clipper. This activity helps learners learn the basic principles of simple machines, engineering design and model building.

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

In this engineering activity, learners construct sturdy geodesic structures out of gumdrops and toothpicks. Use this activity to explore engineering principles as well as sturdy shapes and triangles.

In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).

In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.

In this activity, learners are invited to imagine the park of their dreams!

In this activity, learners explore rocketry and the principals of space flight.

In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

In this activity learners will build roller coasters and test them using small balls or marbles.

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

Learners act as engineers and design mini submarines that move in the water like real submarines.

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

In this activity, learners work in teams to build and test paper airplanes. Learners try to fly their airplanes directly on the runway and earn points for accuracy.

In this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.

In this activity, learners build bridges and cantilevers in a series of "building out" challenges with straws and pins.

In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.

In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

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