Review Study Guide
Give yourself a +, -, or 0 for each topic in the study guide. 

Make Study Plan
Based on your self-rating, what do you need to review? What 3 things can you do to re-learn?

Study
Here are some resources:

• Haiku Practice Test
• Quizlet Flashcards
• Your Science Journal

Self-Score

Give yourself a self score on your science journal using the science journal rubric. 

Periodic Trends

Goal:
Describe the trends in the periodic table. Relate the atomic radius of an atom to its electronegativity.

Agenda
Warmup
Notes
Practice
Quiz

Warmup
Create a new entry in your journal entitled "Periodic Trends." Answer the following question as a CER: 
Are valence electrons more important than other electrons? Use evidence from the labs and activities we have done over the past two days to support your argument. 

Notes
We will take notes on these slides in your science journal. 




Practice
Copy these questions into your science journal and answer them. We will go over the answers in class.

Quiz
Log in to Socrative. 

The Periodic Table

Goal:
Construct an argument based on evidence describing patterns in reactivity on the periodic table.

Agenda:
Warmup
Lab Conclusions
Card Sort

Warmup
Check your journal entry from yesterday. You should have two things completed:

1. Questions from the Bohr model card sort completed.
2. Analysis questions from the lab completed. 

If you haven't finished the questions, do it SILENTLY now. 

If you have finished the questions make sure your elbow partner is finished, then discuss your answers with your elbow partner. We will be sharing out in a few minutes. 

Lab Conclusions
Using the NGSS Crosscutting Concept of Patterns, we need to construct an explanation about how an element's position in the periodic table relates to its properties (i.e. appearance, reactivity). Come up with the following with your group:

1. A hypothesis for how the element's position on the periodic table (both row and column) relates to its properties.
2. A description of evidence from your lab that supports this hypothesis. 

Card Sort
We are going to do another card sort! Arrange the cards based on their properties (without looking at the periodic table).

Directions: Find Be, Mg, Ca, and Sr from the cards. Arrange them in a column like Mendeleev did. From the placement of these elements, arrange the cards in a table (columns, and rows). Elements in each column must have as many things in common as possible. You will observe at least four patterns for each column.

Questions (Science Journal Entry Title: The Periodic Table)

1. What do the sticks represent about these elements?

2. What were the two most significant properties of the elements that helped you form your groups and arrange your table?  Explain.
3. What characteristics did you use for sorting the cards?  Record at least 5 observations of patterns such as colors, shapes, sizes, etc… that are in each column and each row of your table.  
4. Below are 4 possible cards for the element Germanium. Where does Germanium belong in the periodic table? Which card seems most accurate to you? What is your reasoning?
   

   
5. Pick one element in the table below that you think does not belong together in the same group?  Explain your thinking with specific information provided in the table about each element.
   
   

   Cadmium Cd	Moderately soft, silvery solid, metal.	React very slowly with water.	Found in CdCl2 (s)
   Zinc Zn	Moderately hard, silvery solid, metal.	Reacts very slowly with water.	Found in ZnCl2 (s)
   Iodine I	Purple solid, nonmetal.	Reacts slowly with metals.	Found in ICl(s)
   Mercury Hg	Silvery liquid metal.	Does not react with water.	Found in HgCl2(s)

Periodic Table and Valence Electrons

Goal:
Evaluate the argument that valence electrons are more important than other electrons.

Agenda:
Warmup
Metals in Water Lab

Warmup

1. Finish your Bohr Model Cards from yesterday and try to use patterns to figure out how they would be arranged WITHOUT using the Periodic Table. 
2. Create a new journal entry entitled Periodic Table and Valence Electrons. Copy the questions ONLY from this document into your journal and answer them using the Periodic Table you made.

Metals in Water Lab
NOTE: This lab involves EXTREMELY reactive materials. Any indication of poor choices and I will SHUT. IT. DOWN.

1. Copy the Procedures/Observations and Analysis from this lab into your science journal.
2. Complete the lab and analysis in your groups of 2.

Homework

Finish the analysis questions from the lab.

The Bohr Model

Goal:
Be able to draw a Bohr model for any atom and use it to identify the number of valence electrons.

Agenda:
Warmup
Bohr + m&m's
Make Model Cards
Exit Ticket

Warmup
Create a new entry in your Science Journal entitled "Bohr Model" and answer the following questions about the three models shown below:

1. Which model do you think is the most useful? Why do you think that?
2. Which model do you think is the most accurate? Why do you think that?
3. Are the most accurate models always the most useful? Give an example. 

Bohr + m&m's

Work in partners.

1. Copy these questions into your science journal. 
2. Get an expo marker, Bohr model paper, and m&m's from me.
3. Use the model and the m&m's to complete the questions in your science journal.

Make Model Cards

Using what you now know about Bohr models, work with your partner to complete the Bohr model cards I give you.
