Physical Propertiesare used to identify objects.

Can be measured or observed.

• Appearance• Color• Size• Shape• Odor• Weight• Density• Solubility

Volume measured by displacement

Volume = L X W X H

Volume – amount of space an object occupies

Each box has the same volume. Which box has the greatest density?Density is the amount of mass in an object.
