Kiwi DIY it's in our DNA
The task was to create a balloon car using recycled materials.  We first drew our designs, then put them all together.  We ran several tests on them and then changed parts of our car in order to build a car that went the furthest and fastest.  We raced them and then evaluated our design.  We also looked briefly at the science behind our cars - Newton's 3rd law of motion, for every action there is an equal and opposite reaction.
