2B40.10 - Buoyancy - Bowling Ball and Spring Scale

Code Number:
Demo Title:
Buoyancy - Bowling Ball and Spring Scale
Area of Study:
Heat & Fluids
Spring Scale, Bowling Ball, and Water.

Video Credit:  Jonathan M. Sullivan-Wood.

Hang the bowling ball from the spring scale.  Slowly lower the ball into the tank of water until it is completely submerged.  Observe the change in the spring scale readings.

A block of known mass may be used in place of the bowling ball.  Place a beaker of water on the digital scale and then tare.  Pick up the block with the spring scale and lower it into the water until it is completely submerged but not touching the bottom of the beaker.  The mass shown on the digital scale should be equal to the mass lost by the spring scale.
