San Rafael High School physics academy's race is anything but a drag

Physics teacher Steve Temple leaned low over the running track at San Rafael High School, counting down the last few seconds before the next round of competition would begin.

"Ready ... Set ... Go!" Temple shouted, stepping back from the track — and allowing his shadow to fall away from the tiny, solar-powered car in front of him. The plastic dragster lurched, then rolled forward as Temple and the two dozen students, teachers and parents gathered for Friday's race filled the air with cheers.

The students who took part in Friday's competition are members of the Academy of Physics and Technology, a school-within-a-school at San Rafael High that incorporates mathematics, Advanced Placement physics and an introduction to engineering into a demanding two-year program.

Friday's race, in which the students' solar-powered vehicles had to roll up and over a hill at the end of an improvised track, was technically part of the final exam for second-year students in the academy. Yet the sometimes cheering, sometimes gasping, always enthusiastic audience for the competition scarcely felt like a group of test-takers.

How do you make solar panels work better?

Well, we're having a solar car competition tomorrow at school, and since my car's motor and belt drive don't work too well, I need a way to make the car go faster.


Add some small mirrors around the cell to direct more light on it. If the weight of the mirrors is too much, try foil paper, or using a couple large mirrors held by yourself and classmates, directed at your car.
