Learning objectives

1. Define density as mass per unit volume; recall and use the equation:
ρ = m/V

2. Describe how to determine the density of a liquid, of a regularly shaped solid and of an irregularly shaped solid which sinks in a liquid (volume by displacement), including appropriate calculations

3. Determine whether an object floats or sinks based on density data

Success Criteria

• Density can be calculated using the equation: density=  mass / volume

• Taking a repeat measurement and calculating an average will give a more precise value

The mass of an object is the quantity (amount) of matter it is made of.

Mass is measured in kilograms, but density is a property of a material. It tells how concentrated its mass is.

​

Density

The easiest way to determine the density of a substance is to find the mass and the volume of a sample of the substance.
