In this activity, learners build large-scale structures and cantilevers in a series of "building out" challenges with garden poles and tape.

In this inquiry-based activity, learners investigate the basic forces of flight as they construct their own paper glider that represents a rainforest creature from Borneo (large, tropical island in So

In this activity, learners explore the design of tall structures such as skyscrapers and telecommunication towers.

In this activity, learners build rockets and shoot them into the air by stomping on the plastic bottle launchers.

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

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 activity (Lesson 1), learners work in groups to create tide simulations.

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 activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up.

In this goopy activity (page 2 of PDF under GPS: Glaciers Activity), learners will model glacial movement with “gak,” a white glue and liquid starch mixture.

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

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

In this activity, learners will build ramps and test how the laws of physics apply do different objects. Learners will explore physics and cause and effect through this activity.

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

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 create air cannons out of everyday materials. Learners use their air cannons to investigate air as a force and air pressure.

In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.

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

Learners discover that soap can be used to power a boat. Learners make a simple, flat boat model, put it in water, and then add a drop of detergent at the back of the boat.
