1. Do Now
Skim through lesson 1.1 and write down 2 new facts that you want to learn more about.

2. Matter has mass and volume.
Matter & Energy 1.1
Matter has mass and volume.

3. Describe what matter is and demonstrate how to measure mass
Learning Goal:
Describe what matter is and demonstrate how to measure mass

4. I. All objects are made of matter.
Anything that has mass and takes up space
solid, liquid, and gas
Made of atoms (too small to see)
Light & sound are not matter – does not have mass or take up space

5. Physical properties describe a matter.
Characteristics of a substance that can be observed without changing the identity of the substance
Use all 5 senses
Qualitative (Quality)
Deals with descriptions.
Observed but not measured.
Colors, textures, smells, tastes, appearance, beauty, etc.
Quantitative (Quantity)
Deals with numbers.
Data which can be measured.
Length, height, volume, mass, speed, time, temperature,

6. Qualitative vs. Quantitative

7. II. Mass is a measure of the amount of matter
Measuring mass compares the mass of the object to a standard unit
Weight – the downward pull on an object due to gravity
standard unit is kilogram (kg)
base unit is gram (g)
Use a (triple) beam balance to measure mass
Gravity – force that pulls objects together
measured by using a scale (spring scale)
standard scientific unit – newton (N)
common unit – pound (lb)

8. Mass & weight are related but not the same
The moon has less gravity than Earth,
so you weigh less but have the same mass.

9. Learning Goal: Describe what matter is and demonstrate how to measure mass
Time to Self-Assess 5 – Mastered it! 4 – Own it! 3 – Getting there! 2 – Confused! 1 – No clue!

10. Learning Goal:
Describe what matter is and demonstrate how to use different methods to measure volume

11. III. Volume is a measure of the space matter occupies
All matter takes up space
air takes up the space inside a basketball
Volume of regularly shaped objects can be calculated using a formula
Volume = length x width x height (V = lwh)
Units of volume – centimeters cubed (cm3)

12. Volume of a liquid – how much space it takes up in a container
use graduated cylinder
measure in milliliters (mL)
1 mL = 1 cm3

13. Irregularly shaped objects cannot use formula – use displacement
1. Use a graduated cylinder to measure a volume of water
2. Place object in water, note the new volume of the water
3. Subtract the original volume from the second volume, the difference is the volume of the object

14. Learning Goal: Describe what matter is and demonstrate how to use different methods to measure volume
Time to Self-Assess 5 – Mastered it! 4 – Own it! 3 – Getting there! 2 – Confused! 1 – No clue!

15. Density
a measure of the amount of matter present in a given volume of a substance
unit – grams per cubic centimeter (g/cm3)
Density equals mass divided by volume
(D = m/v) M D V
A block of metal has a mass of 12 grams and a volume of 8 cubic centimeters.
What is the density of the block?
M = ______g ____ / ____ = ____
V = ______ cm3 D = ______ g/cm3
