This years senior class science challenge was to build a raft that could float and hold as many marbles as possible. The only materials they could use were lollipop sticks and rubber bands. We had great fun experimenting with different designs in school before the challenge in the McWilliam with all the other schools from South Mayo. Our two teams did really well and their floats held alot of marbles one team being very close to the winning score of 31 marbles! Well done everyone!
