Topic: Understanding structures and mechanisms (pulleys and gears)
Students will research, design, and build (using the materials and tools provided) a geared crank fan. The gears must be arranged so that they are driven by an elastic fan belt, and the fan rotates faster than the crank. The fan can be hand held or stand on a flat surface. Students will record their results, make modifications and re-test (if time permits), and complete a report on the steps they took to solve the design challenge.
