Zip-Line Racers Science Kit
This activity kit challenges students to create a propeller-powered device that travels along a string. The essential pieces—propellers, rubber bands, craft sticks, and string—are provided; it’s up to the young scientists to determine the best materials to use in order to effectively propel their racer. Using the engineering design process, students will create, evaluate, ad redesign their simple machine until their objective is met. Includes enough materials to begin 6 racers.
CHOKING HAZARD. Not for under 3 yrs.
