 Volume
is the amount of space taken up by
an object
 Volume can also mean how much something
holds
 Volume can be measured in many different
units
 Volume can be calculated by using water
displacement!

Finally, find the difference
between the water level
before displacement and after
displacement.

 Density
refers to
“how crowded” the
particles in an
object are!
 Density can be
measured in grams

Find the volume of the object. You can use
water displacement for this or traditional
formulas (L x W x H). Let’s use the metal ball
again. It’s volume was 9.0 ml!
Now find the mass of the object. You can use
a scale for this. .
Mass = 54.0 g
Divide the mass by the volume!
54.0 g ÷ 9.0 ml = 6.0 g/ml
 Pure
water has a density of 1.00 g/ml
 If any material is denser than the fluid that
surrounds it, it will ___________
 If any material is less dense than the fluid
that surrounds it, It will __________!
