After eighth grade science students successfully applied their knowledge of energy and forces to complete their mousetrap cars, they took their engineering skills up a notch and incorporated an alternative energy source to power electric model cars. Students had to work through the challenges of minimizing friction on the car axles and figuring out how to transfer the torque from the motor to the drive shaft. In addition, they figured out a way to make a movable mount for their solar panels to optimize the output of the solar cells. Preliminary trials indicate that they have met the challenge with good focus and skill, and are ready for the Solar car race!
