In the two images above, we can see the COMPACTNESS of molecules. The image on the left depicts molecules in a liquid. The image on the right depicts molecules in a solid. WHICH HAS A HIGHER DENSITY, THE LIQUID OR THE SOLID?

In class today, we measured the mass of a rock using a TRIPLE BEAM BALANCE.
The rock's mass is 189g.
Then we measured the volume using a beaker of water containing 200ml of water.
The rock's volume is 100ml. We convert this to 100ccm (cubic centimeters) because
WHAT DO THE GREEN STARS REPRESENT IN THE PICTURE ABOVE? They are next tokg, g, and mg, the most commonly used labels in metric measurements.
1ml = 1ccm
We know the following:
mass = 189g
volume = 100ml
Remember that our formula is density = mass over volume. d= m d=189 g
v 100 ml
The density of the rock is 1.89 g/ccm.

Here we have examples of the CAUSES for the changes in density.
Density is written in black.
Mass is written in blue. When mass increases, density increases.
Volume is written in orange. When volume increases, density decreases.
When mass and volume increase at the same rate, here it is a rate of 10, then the density stays the same.

There is a lot going on in this picture. There is the NEMONIC, King Henry Died By Drinking Chocolate Milk. This helps you to learn the prefixes for the metric system. REMEMBER the metric system has a base for each measurement.
GRAMS - solid weight
LITERS - liquid weight
METERS - distance

The most important notes here are:
The formula for density is
density = mass
volume
Remember that all measurements must have the correct LABELS.
Mass is measured in grams
Volume is measured in ccm, cubic centimeters
Density is measured in g/ccm, grams per cubic centimeters
