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 construct a simple game to test their hand-eye coordination and steadiness of hand.

In this hands-on engineering project, kids use two simple machines, levers and inclined planes, to construct their own pinball machines.

This fun and simple hands-on astronomy activity lets learners explore model planets (that they or an educator will create), using methods NASA scientists use to explore our Solar System.

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

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

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

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

In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.

In this activity, learners explore the engineering design process and the basic mechanics behind building bridges as they build one themselves using gumdrops and toothpicks.

In this activity, learners explore physics by building a catapult that launches marshmallows with household objects.

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

Learners make their own paper. They start by shredding old newspaper, clean toilet paper, and clean paper towels.

In this activity, learners create night lights using a plastic cup, programmable PICO Cricket, tri-color LED, and sensor.

In this activity, learners create painting machines that can paint moving forwards and backwards.

This activity shows learners how computers use numbers to represent pictures. A grid is used to represent the pixels (short for picture elements) of a computer screen.

Create airplanes from straws and geometric shapes. Test them out to see how far they can fly, or how accurately they can be aimed.

In this activity, learners will learn how to knit using only their hands. Learners will explore patterns and fabrication as well as develop fine motor skills and patience through this activity.

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.
