It is no secret that many high school students are fascinated with automobiles. The activities in "Fueling the Car of Tomorrow"--a free high school science curriculum, available online--(see "On the web")--capitalize on this heightened awareness and provide relevant learning opportunities designed to reinforce basic physics, chemistry, biology, and mathematics principles. The curriculum consists of 17 activities that can serve as a resource for science classes or as the basis of an entire course; each activity is also explicitly tied to state and national science standards (NRC 1996).
