Density: 1599, from L. densus "thick, crowded.”
Less dense More dense
-physical property of a substance that describes the degree of compactness of a substance

Calculating density:
Density = mass / volume
D= m/v
Find density of a ball of aluminum that has volume of 32.4 mL and mass of 87.48 grams.
Find density of a ball of gold that has mass of 38.6 grams and volume of 2 mL.
Which is more dense aluminum or gold?

SINK OR FLOAT? What pattern do you see for those objects that are less dense than water and those that have more density than water?

Density is affected by temperature. Water density decreases as temperature increases and vice versa.
