Density is how tightly packed atoms are to one another in a solid, liquid or gas.For

example an oak log is more dense than a pine log. This means that the atoms are

more tightly packed in an oak log than they are in a pine log. If you had 2 logs, one

pine and one oak that were the same size (volume), the oak would be heavier (have a

larger mass), because it has more atoms in it than the pine does for the same volume.

Density is a relationship between mass and volume and can be found by dividing the

mass of a liquid, solid or gas by its volume.

This experiment was done to figure out the density of the following three solids:

Aluminum, Silicon, and Zinc. The procedure to calculate the density of the above

metals was as follows. The three different metals were weighed separately on the

scale. The mass of the metals in grams was noted and recorded (see chart below).

Ten milliliters of water was placed in a glass measuring cup. The metals were placed

in the cup with ten milliliters of water one at a time and the amount of displaced water

was calculated and recorded (see chart below). The amount of water displaced by each

metal is equal to its volume. The density of the metals was then calculated by dividing

their mass by their volume.


It was hypothesized that Zinc was the most dense.


Metal Mass Displaced Water / Density


Aluminum 1.4 grams 0.6 ml 2.3 g/ml

Silicon 1.0 grams 1.0 ml 1.0 g/ml

Zinc 2.4 grams 0.5 ml 4.8 g/ml

This experiment, accurately calculated the density of Aluminum, Silicon, and Zinc.

Aluminum has a density of 2.3g/ml. Silicon has a density of 1.0g/ml. Zinc has a

density of 4.8g/ml.

The hypothesis that Zinc had the greatest density was found to be correct.
