We read the book WHO SANK THE BOAT?, and experimented with boats made out of aluminum foil (tin foil). We filled the boats with paper clips, pebbles, glass stones and elastics. Some boats sank right away! :( Other boats capsized! :( And some held a lot of stuff before taking on water and sinking! :) Ellie and Jozee made canoe shaped boats. They were the strongest of the girls! Gabe made a boat shaped like a kiddie pool and it was the strongest of the boys! Great job, everyone!
