Overview
Model car races are a common science and engineering activity for youth groups because they are engaging, open-ended and have the excitement of competition. This gives us the chance to work in some great science concepts and engineering practices. The level of presentation can also be modified for different audiences. The Pitsco Sunzoom Lite ($8.95) and Ray Catcher Sprint Kit ($59) have all the materials for an extremely basic solar powered model car.
Procedure
In modeling good scientific experimental practice and engineering design methods its good to start with a basic "control" version of the car just as the kit instruction describe and then try to optimize various factors. As a leader you can guide students through this process with a "socratic" dialogue. For example ask "What could you do to make your car go faster, and win the race?" If they suggest adding more solar cells then "How would you connect the additional solar cells?" , "How would you support them?", and "What do you predict the result will be?
