1. Warm Up You Decide on which one you want to do!
You have a half sheet of paper on your desk and a pink “Warm Up Options” paper.
Put your name on the half sheet of paper and read your options.
Decide which warm up you want to do and complete it on the half sheet of paper.

2. 8.P.1 Understand the properties of matter and changes that occur when matter interacts in an open and closed container.
8.P.1.1 Classify matter as elements, compounds, or mixtures based on how the atoms are packed together in arrangements.
8.P.1.2 Explain how the physical properties of elements and their reactivity have been used to produce the current model of the Periodic Table of elements.

3. TLW Students will explain the organization of the periodic table by drawing and finding patterns in Bohr Models and Lewis Dot structures, completing the first part of a LINK activity and answering an inquiry question using evidence from text read in class.

4. How are subatomic particles arranged?
Bohr Model of the atom:
All of the protons and the neutrons
The 3rd ring can hold up to 8 e-
10P
11N
The 1st ring can hold up to 2 e-
The 2nd ring can hold up to 8 e-
The outermost ring/level of electrons are the
valence electrons

5. Draw Bohr models (atomic models) for

Draw Bohr models (atomic models) for
As a class: “get ye to a white board”
B (Boron element 5)
Na (Sodium, element 11)
On your own:
O (Oxygen, element 8)
Li (Lithium, element 3)

Complete the first two rows, the rest is homework.

7. Determine it’s reactivity (how easily it bonds with other elements.)
Valence electrons
Determine the how an atom bonds with other atoms (or if it will bond at all).
Determine it’s reactivity (how easily it bonds with other elements.)
Atoms with a complete set of valence electrons are stable. They don’t bond with other atoms: menaing they don’t gain/lose electrons, don’t share electrons.
Word origin/stem
late Middle English: from late Latin valentia ‘power, competence,’ from valere ‘be well or strong.’
P 12

8. (because the other e- are in full rings and aren’t going anywhere)
Lewis Dot Structures
The behavior of an atom is determined by the VALENCE ELECTRONS…so wouldn’t it be easier to just draw those??
(because the other e- are in full rings and aren’t going anywhere)
Write the symbol for the element
Calculate the number of valence electrons (Use dots to represent the electrons.)
Place electron “dots” around the symbol, starting on the left and moving clockwise.
Begin by placing only one electron dot per side of the element symbol.
More than 4 valence electrons? Add the second dot to each side (clockwise)
Max of two electron dots per side

9. Lewis Dot Side…complete the first two rows, the rest is homework.

17. Turn & Talk
Talk to your seat partner about everything you have learned about: Atoms Periodic table Subatomic particles Atomic Models

19. Warm Up Option 1: Metacognitive reading of the standard.
Copy the standard and objective onto your half sheet of paper, as well as the table below it:
Understand the properties of matter and changes that occur when matter interacts in an open and closed container.
Explain how the physical properties of elements and their reactivity have been used to produce the current model of the Periodic Table of elements.
Read and annotate the standard (“talk to the text”).
Complete the table while or after you have read and annotated the standard.
Warm Up Option 2:  Organizational Brainstorm
Copy the table onto your half sheet of paper
In each column, list the different ways each type of item can be organized:  (clothing in a closet or food in the kitchen.) 
Be sure to include WHY you have organized the items that way
I thought, noticed, inferred
Connections, questions I have
Clothes in the closet
Food in the kitchen
