Who this list is for
Young engineering teams can use this balloon car challenge supply list to build cars powered by escaping air. It keeps the work centered on one clear floor-lane challenge rather than a large collection of unrelated craft materials.
How to use this list
Give each team a small cardboard rectangle, four plastic bottle caps, two blunt-ended wooden skewers, and two plastic drinking straws for the car base and axles. Use a latex balloon and flexible drinking straw for the air-powered design. Mark race lanes with painter’s tape, measure each run with the measuring tape, and record distance on the distance recording sheets.
Common mistakes
Do not set up the car before checking that the bottle caps can turn freely around the skewers. Keep the floor lane clear and use the same starting line for every run. Teams should test one change at a time, such as tape placement or balloon position, rather than rebuilding every part at once.
What is on this list
Each team needs cardboard rectangles, bottle caps, skewers, plastic straws, latex balloons, flexible straws, rubber bands, rulers, and scissors. Shared supplies include masking tape, painter’s tape, a measuring tape, recording sheets, and pencils. Cross off supplies already in the classroom.
Before you go
Scale cardboard, wheels, axles, straws, and balloons to the number of teams. Check the floor space for a straight, clear race lane. Keep extra balloons available because a balloon may tear or be hard to inflate during testing.
