1. Aim: What is density and how can it be measured
Aim: What is density and how can it be measured? Do Now: What is the difference between something being dense and something being heavy?

2. Heavy
Dense

3. Matter
Matter is anything that has mass and occupies space. In other words, matter is anything that has mass and volume.
The main three states of matter: solid, liquid, and gas. The particles are arranged differently in each state of matter.

4. What is mass?
Mass is a measurement of how much matter is in the object.
Units
English vs. Metric
Which is Larger?
1 Pound or 100 Grams
1 Kilogram or 1 Pound
1 Ounce or 1000 Milligram

5. Mass

6. Measuring Mass

7. What is Volume?
Volume is a measure of the space occupied by a sample of matter
Basic Unit is a liter (L or l)
1 Liter (l) = 1000 milliliter (ml)
1milliliter (ml) = 1cm3 (1c.c) = 1 gram
Which is larger?
1 liter or 1500 milliliters
200 milliliters or 1.2 liters
12 cm3 or 1.2 milliliters

8. Measuring Volume

9. Measuring Solid Volume

10. Density Density is ratio of mass of an object to its volume.
Density is an intensive property that depends only on the composition of a substance, not on the sample.
An intensive property is a property that depends on the type of matter in a sample, not the amount of matter.

11. Sample Problems
Your teacher gives you a little square block metal which is exactly 1 centimeter cubed. It is small, but weighs 4.5 grams. What is its density?
A piece of metal weighs 3 grams and has a density of 2.70 grams per cubic centimeter. What must be its volume?
