Draggin' Boats
Source Institutions
Learners design, build, and test models of "dragon boats" made from up to three milk cartons.
Stomp Rocket
Source Institutions
In this activity, learners build rockets and shoot them into the air by stomping on the plastic bottle launchers.
Blow It Away
Source Institutions
In this activity, learners design wind-powered cars out of simple household materials. Students have fun designing and then racing their vehicles around the room.
Watercraft
Source Institutions
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.
Fly a Hot-Air Balloon
Source Institutions
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.
Zip Line Zoo
Source Institutions
In this activity, learners build a stuffed-animal zip line. Learners hold a cord against a wall, hook a cute stuffed animal onto it, let the animal slide down, and records its travel time.
Rubber Band Car
Source Institutions
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.
The Muddy City: Minimal Spanning Trees
Source Institutions
In this puzzle, learners investigate the decisions involved in linking a network between houses in a muddy city.
Zipline
Source Institutions
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.
Pop Can "Hero Engine"
Source Institutions
In this activity, learners build water-propelled engines from soft drink cans.
Elevator Engineering
Source Institutions
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!
Build a Bridge
Source Institutions
In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.
Ice Roads: Steiner Trees
Source Institutions
In this outdoor activity, learners use pegs (like tent pegs) and string or elastic to simulate drill sites and roads in Northern Canada.
Puff Car
Source Institutions
In this activity, learners are challenged to design a wind-powered car using only a handful of household materials.
Target Practice
Source Institutions
In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.
Parachuting Pinwheel
Source Institutions
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.
Motorized Car
Source Institutions
In this design challenge activity, learners build a car that uses a battery-operated motor to "drive" at least ten feet.
Balloon Rocket
Source Institutions
Experiment with force and pressure by building a balloon rocket. When launched, the balloon will run a track wherever you place the string.
