INSTANT CHALLENGE CABLE CAR
There are many ways to solve a problem. Sometimes it is as simple as applying a piece of duct tape. Other times it takes months or years for a product to progress from an idea into full-scale production. Often engineers and designers use a specific set of steps (called a design process) to find the best solution to a problem. In this activity your team will quickly design the solution to a problem using a design process that progresses from brainstorming to presenting a final design.
In a team of three, using only the materials provided, design and build a device or vehicle to move a small figure (or other object) as far as possible across the room on the fishing line cable. A team member may initiate the motion of the vehicle or device but may not provide forward momentum.
Brainstorm (5 minutes). As a team, brainstorm as many ideas for your device/vehicle as possible as the recorder documents your ideas. You may handle and inspect the materials, but you may not alter or connect any of the materials in any way during this phase. Select one of your sketched ideas to pursue.
Build (10 minutes). Build your device. Make changes to your original ideas as necessary.
Test (1 minute). Each team will have one minute to test their device on the fishing line cable.
Brainstorm, sketch, annotate, design, build, test, redesign, build and test again! Write your reflections in your engineer's notebook!
