(2B40.20) Archimedes’ Principle
In this demonstration, first find the initial weight of the can/weight system that is being submerged in the beaker of water by using the scale. Once the system is fully submerged there will be a drop in the reading on the scale. This is due to the buoyancy force opposing the force of gravity. The displaced water can later be poured into the empty can to show that its weight is equivalent to the bourancy force.
