1. DATE A/B Day
LEQ: As matter changes states, how does
the movement and arrangement of the
particles change with it?
1. What does the atomic number tell us?
2. What does the atomic mass tell us?
3. How can we figure out how many neutrons are in a
particular atom?
4. How can we tell how many electrons are in an
atom?
6. Energy Levels: hold electrons with the same
amount of energy
1st Energy Level
2nd
3rd
DRAW THIS IN YOUR NOTES!
7. Drawing Electrons and Energy Levels: Helium
Protons: 2 WHAT NUMBER
Neutrons: 2 ROW IS IT IN?! 1
Electrons: 2
8. Drawing Electrons and Energy Levels: BORON
Protons: 5 WHAT NUMBER
Neutrons: 6 ROW IS IT IN?! 2
Electrons: 5
9. DRAW YOUR OWN!
Pick TWO elements and draw models of each of them.
You must choose ONE element from the first energy
level and ONE from the second energy level
BE SURE TO:
LABEL each element you draw
DRAW “+” signs in your protons
INCLUDE the correct number of protons,
neutrons, electrons
DRAW electrons in their correct energy
level
10. Summarizer:
In 3-5 sentences, EXPLAIN how we can use the
periodic table to determine the structure of an
atom.
YOUR ANSWER MUST INCLUDE THESE WORDS:
PROTON ATOMIC MASS
NEUTRON ATOMIC NUMBER
ELECTRON ENERGY LEVEL
11. Today’s LEQ: As matter changes states,
how does the movement and arrangement
of the particles change with it?
By the end of today, you should be able to…
1. Describe the three types of matter
2. Explain how the movement and arrangement
of the particles change as the state of matter
changes.
15. Matter: anything made of atoms

16. 1. Which state of matter is
MOST compacted?
2. Which state of matter is
the LEAST compacted?
3. Which state of matter is
the MOST DENSE? Why?
4. Which state of matter is
the LEAST DENSE? Why?
17. In your notebook…
1. Use the periodic table to list all of the
elements that naturally occur as gases
2. Use the periodic table to list all the elements
that naturally occur as liquids
3. Use the periodic table to list 5 elements that
naturally occur as solids
HOT Q: WHAT DO YOU NOTICE
ABOUT THE GASES?
18. THINK-PAIR-SHARE
1. PICK AN ELEMENT
2. Use your knowledge of the different states of
matter to describe some characteristics of the
substance you chose
19. HOT Q:
Which state of matter has a definite
volume but NO definite SHAPE?
Hint: it can change it’s shape based on
the container it is in
20. • Video – Brainpop (matter of changing states)
What causes matter to change states?
When matter changes states, do the
chemical properties or the atoms
change?
21. HOT Q:
When matter changes states, do
you think this is a chemical change
or a physical change? Why?
(HINT: Think about chemical vs.
mechanical weathering!)
22. Finish the paragraph…
A student is doing an experiment with a substance
called X. The substance is naturally found in solid
form. Once X is heated, it forms a liquid and the
particles 1. [get closer together/spread further
apart]. Once X is in its liquid form, it is 2.
[more/less] dense than its solid form. After X
becomes a liquid, the student heats it more until it
becomes a 3. [solid/gas]. In this last state of
matter, the particles 4. [are not packed together at
all/are loosely packed together]. In this final
state, the particles in X 5. [move past each other
freely/have limited movement].
