1. Measuring Matter
Chapter 2 Section 2

2. 1/6 of what you weigh on Earth!
Weight
Weight is a measure of the force of gravity on an object.
Would your weight be the same if you were on the moon?
You would weigh about
1/6 of what you weigh on Earth!

3. MASS Measurement of the amount of matter in an object.
Does your mass change on the moon?
A physical property

4. 1,000 Units of Mass International Systems of Unit “SI”
SI unit of mass is the KILOGRAM.
How many grams are in a kilogram?
1,000

5. What is my mass?
= 150 grams
= 5 grams

6. Volume The amount of space that matter occupies.
Liquids, Solids, & Gases have volume.

7. Units of Volume 1 Liter bottle = 1,000 milliliters 1 milliliter =
liter (L)
milliliter (mL)
cubic centimeter (cm³)
1 Liter bottle =
1,000 milliliters
1 milliliter =
1 cubic centimeter

8. What is my volume?
= milliliters
= 355 milliliters

9. Calculating Volume
Volumes of solids are usually expressed in cubic centimeters
Volume = Length x width x height
Don’t forget to label the units!
How do you measure the volume of an irregular object?
If a penny makes the water go up 4 milliliters, what is its volume?
4 cubic centimeters
Water level rise = Volume of object in milliliters

10. Density Density relates the mass of a material in a given volume. NO!
Two materials have the same volume, do they have to have the same mass?
Density
Density relates the mass of a material in a given volume.
NO!
A kilogram of sand takes up much less space than a kilogram of feathers!
# of grams in one cubic centimeter
The volumes differ because they have different densities.

11. every gram of water has a volume of 1 cm³
Water at room temperature =
Density of Water
1g/cm³
This means:
every gram of water has a volume of 1 cm³
