Floating boats graphs

Today we were learning about Thailand's  festival Loi Krathong. Part of this festival is the floating of boats down a river. The boats are made from leaves and have candles on them. In our class activity, we made boats from foil. Then we put marbles on the boats while they were floating to see which design held the most marbles without sinking. We also made graphs to show the amount of marbles for each child.
