Inform students that their challenge is to design a vehicle from the supplied materials and that they will be calculating the speed at which their vehicles can travel. Students will have several trial runs and time to alter their car. On the last day of the activity a race will be conducted. The goal is to design a car that will travel as far as possible. Students work on design of vehicle and begin construction when plans are agreed upon within the team.
