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

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 construct three quick and simple mechanisms to start building a pop-up book. Learners fold, cut, and glue paper to make a bird beak, parallelogram, and V-fold.

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

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

In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers.

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

No glue is needed for learners of any age to become marshmallow architects or engineers.

In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.

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

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.

Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.

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 build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

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.

In this activity, learners construct wands that play different notes depending on information from light sensors programmed via a PICO Cricket.

In this activity, learners build mini-basketball courts using cardboard and measuring spoons. Use this activity to introduce learners to catapults, forces, and levers.

In this activity, learners build a racecar using only a rubber band, spool, straw, and paper clip! This racer is a classic toy that zips across a flat surface.

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

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