2B40.11 - Weight in Water




Code: 2B40.11


Demo Title: Weight in Water


Subject: Density and Buoyancy


Description:
Showcase the the buoyant force by weighing an object with a spring scale, then weighing it again when it is submerged in water. Use the change in weight and volume to determine the material of the object.


Procedure:

  • First, use scale on the 1 kg mass.
  • Then, se the scale on the unknown mass cylinder and note the reading of the scale.
  • Submerge the unknown mass cylinder into the water and note the reading of the scale.
  • Explain volume, buoyant force, and density to tell us what the material of the cylinder is.
