The density of a stick of butter is calculated to determine if it will sink or float in water.
This lesson teaches students about density, how to calculate it, and how it is related to determining whether an object will sink or float.
Properties of matter (density)
Density can be calculated using the mass and volume of an object. If an object is denser than the water it displaces, it will sink.
If an object is less dense than the water it displaces, it will float.
