Over the last 3 weeks we have been working on a challenge with our buddy class. First we had to design something using recycled materials that would float on water and also hold at least 5 marbles. The challenge was to make it look like a boat and hold as many marbles as possible. The buddies drew detailed designs and listed materials they would use. Over two lessons they made their creations and tested them in water as they went. Many had to adjust their design and make changes as it didn’t float! Students were really engaged in the process and used great team work and problem solving skills. Here are the finished creations tested in a tub of water:
