Experiment B02    Density and Buoyancy

Objectives
  • Study the Archimedes' principle for a floating object
  • Study how the buoyant force is related to the weight of liquid displaced
  • Compare two methods in measuring the density of a liquid
  • Learn to use basic equipment to measure mass and volume of objects
Description
In this activity, you will study the buoyancy of an object in water.

In Experiment 1, you will measure the density of water and iron using simple technique.

In Experiment 2, you will verify the Archimedes' Principle.

In Experiment 3, you will compare the buoyant force and the weight of water displaced by immersing an iron cylinder into water.

In Experiment 4, you will measure the density of brine solution by comparing the buoyant forces.
