Density Drill
Some objects tend to be “heavy,” while other objects seem “light.” But unless you are comparing the same volume
of each object, these descriptions have little value. And that is where the concept of density comes in. For density refers
to how much mass an object has in a particular volume. Scientifically, density is described as mass per unit volume, or
Density = mass/volume. Because mass is measured in grams and volume is measured in cubic centimeters, the unit for
density is grams per cubic centimeter.
If the mass and volume of an object are known, its density can be determined by dividing the volume value into mass
value. Similarly, if the density and mass are known, the object’s volume can be determined by dividing the density
value into the mass value. Finally, if an object’s density and volume are known, its mass can be found by multiplying
these two values.
You can see how density, mass and volume are related by doing this activity. In each situation, you are given enough
information to determine the unknown value in the formula D = M/V
