Explore the basics of gears with the Gear Car kit. The cars come in sets with two different gear ratios that allow students to investigate the effect of gear ratio on the car's performance (speed and power). This tool comes with curricula that includes a powerpoint, a video link, and an investigation and can be used as is, or modified for your class. The lessons and cars can be used as a stand alone investigation or to prepare students for designing a Solar Car.
