In this design challenge activity, learners use a balloon and other simple materials to design an air-powered rocket that can hit a distant target.

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

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.

In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

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

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

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 design challenge activity, learners build a device to carry a Ping-Pong ball from the top of a zip line to the bottom in four seconds (or less!).

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 design challenge activity, learners build a car that can travel at least four feet using rubber band power and use the design process to debug problems.

In this puzzle, learners investigate the decisions involved in linking a network between houses in a muddy city.

In this activity, learners will use household items to design and build an elevator that will carry 2 passengers to a height of 16 inches...or higher!

In this outdoor activity, learners use pegs (like tent pegs) and string or elastic to simulate drill sites and roads in Northern Canada.

Build a pinwheel that works without wind! This activity contains steps on how to build a parachuting pinwheel out of paper, a film canister, and some brads.

In this design challenge activity, learners build a car that uses a battery-operated motor to "drive" at least ten feet.

Experiment with force and pressure by building a balloon rocket. When launched, the balloon will run a track wherever you place the string.
