I want to do this one the month before the Pinewood Derby, so we can do a demonstration at Pack Meeting. This is for part of requirement #4—Pinewood Derby Experiments (see p. 383 in handbook). We are going to do this to see what makes the best Pinewood Derby car. We’ll have a number of different cars ready to test where the best place is to put weight, shape, graphite on the wheels, etc. After determining the best options, we’ll give a demonstration at Pack Meeting, with the hopes that it will help everyone get ideas of how they want to build their own cars.

You could do parts of requirements #3 and #4 in conjunction with a space derby (see notes on Build My Own Hero).
