Density

Density is a measure of......

• How much mass is in an object

• How much space and object takes up

• How tightly packed the matter is

We test for density by seeing if an object will ______________ in water.

• sink/float

• dissolve

• heat up

• cool off

Objects that are buoyant

• float

• sink

Look at the picture. The ices cubes float, so the water is more/less dense that the ice cubes.
