Concept of density. This YouTube video will provide information about the concept of density. It’s great to use as an introduction to the topic or as a way to summarise the topic.

Outcomes:

• Describe how the concept of density relates to an object's mass and volume.
• Explain how objects of similar mass can have differing volume, and how objects of similar volume can have differing mass.
• Explain why changing an object's mass or volume does not affect its density (ie, understand density as an intensive property).
• Measure the volume of an object by observing the amount of fluid it displaces.
• Identify an unknown material by calculating its density and comparing to a table of known densities.
