Using the Solar Car Assembly is a great way to experiment with gear ratios and the angle and intensity of solar light. With three gear ratios, high speed (1.7:1), mid speed (2.2:1), and low speed (3.4:1), you can see the difference gear ratios make under different conditions. Experiment under a variety of conditions (sunny, cloudy, etc.). The ball-mounted solar panel allows you to angle the panel towards or away from the sun, showing how direct and indirect solar light can affect power. Solar panel provides power for the motor, which drives the rear wheels.
