When Will It Sink?

Each student had to predict how many bears would fit into their boat that they made out of a piece of foil. Our predictions ranged from 1 to 28, most of the class said 10. After their predictions they go to test to find out the real answer and man were we in shock when everyone began testing their boats because their predictions were no where close to their outcome. The lowest number of bears that we had was 60 and our highest was 163!! They were so excited!
