Given a 15 x 15 cm square of aluminium foil build a barge that will support the most weight.
Students come up with many great designs but surface area is key here. A simple square barge usually emerges as the winner.
The barge captain must take care to not over load his barge and send it to Davey Jones’ locker. Knowing when to say when and not getting greedy are the traits of a skilleed barge captain.
Pennies are added one at a time until the captain makes the call to stop or the ship is sunk. Classroom record is 89 pennies but be careful if you sink your ship you have to bring treats for the class.
