This Demo demonstrates Archimedes' Principle which states that any body submerged in fluid is acted on by an upward force. This is known as buoyancy. The first step is to show the spring scale's measurement simply holding the mass, beaker with water in it. The beaker below sitting in top of a lab jack has  water in it right at the hole in the side of the beaker. Raise the lower beaker so the mass is slowly lowered into the beaker of water.  The water displaced is collected.  Nite how the weight measured by the Spring Scale decreases as the mass is submerged due ti the buoyant force. Once the mass is fully submerged, pour the displaced water into the bucket above the mass and see that the spring scale returns to the original weight.  The weight of the displaced fluid is equal to the buoyant force.

Description:

This Demo demonstrates Archimedes' Principle which states that any body submerged in fluid is acted on by an upward force, the buoyant force. The first step is to show and record the spring scale's measurement simply holding the mass of the bucket and mass system. The beaker below sitting on top of a lab jack has water in it right at the hole in the side of the beaker. Raise the lower beaker using the lab jack so the mass is slowly lowered into the beaker of water. The water displaced is collected. Note how the weight measured by the Spring Scale decreases as the mass is submerged due to the buoyant force. Once the mass is fully submerged, pour the captured displaced water into the bucket above the mass and see that the spring scale returns to the original weight. The weight of the displaced fluid is equal to the buoyant force.
