Start by allowing each team to have a trial run. The teams can then have some time to carry out any improvements to the design of their vehicles.

Then hold the final race run. How far did the furthest vehicle travel? Did they all make it past a certain distance? Which vehicle travelled the fastest? Which vehicle won?

After the race, get the different teams together and see if you can think about why some of the vehicles did better than others. What improvements could you make to the various designs? Can you combine the best of each design to build a super-vehicle?
