Remember Matter? 0 Matter – anything that has mass and takes up space

Physical Properties 0 Characteristics of materials 0 Color, shape, texture 0 VOLUME and DENSITY

Volume 0 Amount of space that matter takes up

Density 0 Amount of mass in a defined amount of space 0 If you know mass and volume of an object, you can calculate density.

Compare Density of 2 Blocks 0 Wood and aluminum 0 Same size 0 Same volume 0 Take up same amount of space 0 Different materials 0 Different masses

Compare Density of 2 Blocks 0 Heavier block more dense 0 Greater mass in the same volume

Compare Density of 2 Blocks 0 Place blocks in water to compare densities 0 Sink or Float 0 If it floats, its LESS DENSE 0 If it sinks, its MORE DENSE
