Cherrywood Community Primary School
Stem Day 7.2.24 Building Castles
Challenge for Elm Class:
Help! We’re under attack! We need to build a castle fort to protect ourselves from the cannonballs.
Children to experiment with building castles out of paper straws, newspaper, toilet rolls or cards. The competition is to find the most stable fort that can withstand the most tennis ball attacks before it falls over.
Questions – will shorter straws mean more stable?
Will layers of straws add stability?
How can you make paper strong? (folding, concertinaing etc).
How can we create stability?
