About This Product
The cylinder is weighed in air and then in water, and filling the bucket with water shows that the loss of weight equals the weight of liquid displaced. This gives students a direct check of Archimedes’ principle and a basis for work on density and flotation.
Frequently Asked Questions
How does the Archimedes Principle Kit show the principle?
The cylinder fits the hollow bucket exactly, so the bucket holds a volume of water equal to the cylinder; this lets students compare the loss in weight of the cylinder in water with the weight of water it displaces.
