These questions have now been answered, at least in part, through the experiments of the day. On one end of the string: the vehicles created from a technical drawing. On the other end of the string: a hook on which hangs washer weights. When the number of washers is increased, the vehicles move quicker. When weight (wooden blocks) is added to the vehicle, more washers must be used. Students timed their experiments and recorded their findings.
