After working in teams to design and 3D print CO2 dragsters, seventh graders in Gregg Kleiman’s science class tested out their miniature racecars on a 30-foot track in the Rao Innovation Center. In this unit, students studied the relationship between friction, drag, and weight while considering the materials used for construction to design their own vehicles. CO2 dragsters must be built to certain specifications to avoid interference with the propulsion system, wheel placement, launch system, and guidance system, as well as the prevention of failure or destruction during testing.
A little friendly competition allowed students to compare and analyze the different designs for success and needed improvements. In today’s race, the team with the lightest weight dragster took home the win.
