Density Density= Mass/Volume Physical property of matter amount of matter in a given amount of space. (amount of matter is called “mass,” and amount of space an object takes up is called “volume”) Density= Mass/Volume http://www.youtube.com/watch?v=FSupQZQqaPk

Density How do we find mass? How do we find volume?

Density How do we find mass? How do we find volume? 1 mL= 1 cm3 triple beam balance, scale How do we find volume? multiply length, width, and height use displacement method 1 mL= 1 cm3 (centimeter cubed/cubic centimeter= cc)

Density Water has a given density of 1g/mL Things that are less dense will float on water. Things that are more dense will sink.
