1. Bell Ringer: On the blank side of a notecard create A,B,C,D sides
Write your name at the top on the back side
Homework: Classify Matter Table

2. Everything that has mass and volume is called matter
What is matter?
Everything that has mass and volume is called matter
It cannot be created or destroyed

3. Kinetic Molecular Theory
all matter is made up of small particles that are always in motion.
The kinetic energy (speed) of these particles increases as temperature increases.

4. Phases of Matter
Solid
Liquid
Gas
Plasma

5. Solids- (s) Kinetic Molecular Theory very low KE - particles vibrate
but can’t move around
fixed shape
fixed volume
Kinetic Molecular Theory
Molecules are held close together and there is very little movement between them.

6. Kinetic Molecular Theory:
Liquids-(l)
low KE - particles can move around but are still close together
variable shape
fixed volume
Kinetic Molecular Theory:
Atoms and molecules have more space between them than a solid does, but less than a gas (ie. It is more “fluid”.)

7. Kinetic Molecular Theory:
Gases-(g)
high KE - particles can separate and move throughout container
variable shape
variable volume
Kinetic Molecular Theory:
Molecules are moving in random patterns with varying amounts of distance between the particles.

8. QUICK CHECKS: Classify the following image as
a. (s) b. (g) c. (l) d. (aq)

9. Classifying Matter- Pg 18 & 19
Atoms
Compounds
Mixtures

10. Atoms Building blocks of matter- cannot be divided
Made up of protons (p+), electrons (e-), neutrons (n0)
Also known as an element Li Li Li Cl Cl Cl

11. Diatomic Elements BrINClHOF
Atoms that must be bonded to something due to their instability
When alone they bond to themselves Cl Cl Cl Cl

12. Compounds 2+ elements chemically bonded together
Must undergo a chemical change to break apart Li Li Li Cl Cl Cl

13. QUICK CHECKS: Classify the following image as
a. Element b. Diatomic Element c. Compound d. Mixture

14. Homogeneous Mixtures
2+ elements or compounds that are evenly mixed together
There is no visible layer
Can be separated through physical means Li Cl Al Al Li Cl Cl Al Li

15. Heterogeneous Mixtures
2+ elements or compounds that are unevenly mixed together
There is a visible layer
Can be separated through physical means Li Cl Al Al Li Cl Cl Al Li

16. QUICK CHECKS: Classify the following image as
a. Element b. Heterogeneous Mixture c. Compound d. Homogeneous Mixture
