Sink or Float? P5 STEM
22nd Jun 2026
Our P5 children took on the challenge of building boats out of tin foil to see how many marbles they could hold before sinking.
Through trial and error, they discovered how shape and surface area impact buoyancy.
A fantastic experiment and great fun was had by all!
