In this engineering activity, learners investigate the differences between the strength of bridges made from flat and round building materials.

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

In this activity, learners examine baking powder, a combination of three powders: baking soda, cream of tartar, and cornstarch.

Based of the The Tech Challenge 2015, learners will engage in two mini-design challenges related to seismic engineering.

In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

In this activity, learners build small animated toys that move.

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

What's a more compelling problem to solve than being stranded on a deserted island?

In this activity, learners cut out and fold their own collapsible origami starshade, an invention that shields a telescope's camera lens from the light of a distant star so that NASA scientists can ex

In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

Learners work in groups to construct bridges using stale marshmallows and toothpicks.

In this design challenge, learners will create their own roller coaster using household objects for the track and a marble or small ball as their cart.

In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.

This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.

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

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

In this design activity, learners create a vehicle that can transport a load, like a favorite toy or as a recycled object, from the top of a zipline to the bottom using only gravity.

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

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.
