Just like all matter water has physical properties that can be measured and calculated. To find the mass of water you will need a beaker and a scale. First find the mass of the empty beaker. Next, fill up the beaker to your desired amount. Then use the scale to find the mass of the filled beaker. To find the mass of just the water, subtract the mass of the empty beaker from the full beaker. Our sample is 100 grams.
The volume of water can be measured using a graduated cylinder. Our sample is 100ml.
Density is calculated by dividing the mass by the volume. Plug in our measured mass at 100 grams and divide that by our measured volume of 100 ml. Water's density is 1 g/ml.
Objects with a density greater than 1g/ml will sink when placed in water. Objects with a density less than one will float when placed in water. If a block has a density of 0.1g/cm3 it will float because it's density is less than 1. Another block with a density of 0.5g/cm3 will also float because its density is less than 1. Notice that more of the block is below the waterline. A block with a density of 0.9g/cm3 is more dense so more of the block will be below the waterline. We can see that as density increases more of the block is below the waterline. Scientists have discovered that the blocks density will tell us exactly where the block will come to rest. If the density is 0.1g/cm3 then 10% will be below the waterline. To calculate where a block will come to rest just convert the density to a percent.
Density explains why ice floats. If you freeze water it expands. The black dots represent the atoms in water. No new atoms were are added to the water so because of the expansion there is more room between the atoms. Compared to the atoms in liquid water, the atoms in the ice are not as tightly packed together causing the ice to float. Try calculating density of ice for yourself. If you get a number less than one it will float. You can also predict how much of it will be below the waterline.

In this video Paul Andersen explains how density measures the compactness of a material. You can calculate the density of a material by measuring the mass and dividing this by the volume. Water displacement is an effective way to measure the volume of an irregular object.

The video explains density and some density facts. Learn why diet cola floats and regular cola sinks in water. Also see why hot air balloons stay in the air. Then hear that if you cut an object in half the density stays the same. Next, see where objects come to rest when placed in water. Lastly learn why ice floats.

Other useful things to know:
-The higher the temperature, the less dense something is.
-Comparing the solid and liquid forms of the same substance, it is a general rule that the solid is more dense.
-Temperature and pressure are directly proportional. If we compress a gas, it gets more dense.

Density
The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume. The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume:
where ρ is the density, m is the mass, and V is the volume. In some cases (for instance, in the United States oil and gas industry), density is loosely defined as its weight per unit volume, although this is scientifically inaccurate – this quantity is more specifically called specific weight.
For a pure substance the density has the same numerical value as its mass concentration. Different materials usually have different densities, and density may be relevant to buoyancy, purity and packaging. Osmium and iridium are the densest known elements at standard conditions for temperature and pressure but certain chemical compounds may be denser.
To simplify comparisons of density across different systems of units, it is sometimes replaced by the dimensionless quantity "relative density" or "specific gravity", i.e. the ratio of the density of the material to that of a standard material, usually water. Thus a relative density less than one means that the substance floats in water.

016 - Density
In this video Paul Andersen explains how density measures the compactness of a material. You can calculate the density of a material by measuring the mass and dividing this by the volume. Water displacement is an effective way to measure the volume of an irregular object.

Other useful things to know:
-The higher the temperature, the less dense something is.
-Comparing the solid and liquid forms of the same substance, it is a general rule that the solid is more dense.
-Temperature and pressure are directly proportional. If we compress a gas, it gets more dense.

Against The Spirits
There is a God and I bow and you will hate me for it!
Duty to humble my soul to a speck of dust and you'll hate me for it!
Ageless understanding of love from the heavens and you'll hate me for it!
Serenities balance is my innermost peace and you will hate for it!
Your world is against the spirits! This is day is against the spirits!
I gladly detach my soul from the lies that sicken this day.
Disregarding the metric wickedness that decays my inner space.
There is something inside myself that can't become this "sickness."
Reminded once more that the quest for the top is coldness!
I will love God of "Zion" with all my heart and you will hate me for it!
Intentions will be so helples and you will hate me for it!
I will love through resurrecting eyes and you will hate me for it!
Self exultation is the opiate of the masses.
