Car Project
Vroom, vroom, vroom.  Did you lose your car project?  Well, I suppose you could just fudge it, build the car any way you like and take the "F" like a toughguy.  Or, you could build the car out of rolled up fifty dollar bills, which would guarantee that I would give you an "A", even if you didn't follow any of the directions.  Or, I guess you could download another copy of the rules and data sheets. (Although I would much prefer the car made of fifty dollar bills.  Really.  I'm serious.  I can use the money.)

The Car Project is in a pdf format.  If you can't read it, you need to download Adobe Reader.  It's free and you can get it here:
