Float a Boat

Today's science lab was all about buoyancy. The girls had a boat building contest. Each, using the same amount of clay, had to design and build a boat. The goal is to make the boat that will hold the most pennies while floating. They were given a half hour to design and test their boats to make sure they float before the penny holding contest starts.

And the winner is... KATRIANA'S GREEN LEAF BOAT!
