The amount of space that matter takes up
Volume
Multiply the height times the length times the width.
What is the difference in density between 5 cubic centimeters of water and 100 cubic centimeters of water?

100 cubic centimeters
How does temperature affect density?
When something is heated, its density decreases.

Temperature
How would you find the density of a substance?
Divide its mass by its volume.
Which is denser, ice or liquid water? Why is this important?
Ice is less dense than water. This is important because ice floats on top of water allowing animals that live in water to survive in winter.
