2. Agenda Catalyst Paired Reading Mini-Lab Exit Ticket

3. Paired Reading One partner reads while the other partner annotates. Switch off reader and annotater so that both partners do both roles. Answer three questions at bottom. You have 15 minutes!

4. Mini-Lab All materials at lab stations EXCEPT: – Alum – come get this from Ms. Kline Record observations in the table while you are doing the lab. When you have finished, rinse out the beakers in the sink at the back of the room, and leave your beakers there.

5. Exit Slip Tell me: 3 – things you learned today 2 – things you want to learn about this unit 1 – fun thing you are going to do this weekend.

10. Mini-Lab All materials at lab stations Record observations in the table while you are doing the lab. When you have finished, rinse out the beakers in the sink at the back of the room, and leave your beakers on lab tables.

11. Lab You will have 5 minutes per station. ALL materials are at your station. You will rotate two stations each time you rotate. Dump all solutions into the WASTE beaker, rinse out containers, and leave at station.

12. Exit Ticket What are the four indicators of a chemical reaction? What is an indicator of a physical change? Which station did you find most interesting today, and why?

13. Wednesday, March 4, 2015 Catalyst: According to Figure 1, over the 12 month period, the monthly precipitation at the urban site was maximum in February and minimum in July. According to Figures 2 & 3, which ion was also maximum in February and minimum in July? a.Cu 2+ b.Zn 2+ c.Cl - d.SO 4 2- Classroom expectations: 1.Wear Kenwood ID. 2.Cell phones, music players, and headphones are put away. 3.Food is disposed of or put away. 4.Dressed appropriately. 5.Notebook is out and you are ready for today’s class.

17. Groupwork You MUST use your role cards! Indicate your role at the top of the page. The recorders is the ONLY one that will be submitted and graded. Grade: completed packet, using role, participating in discussion after.

18. Discussion Protocol 1 st responder: Answer question with explanation. 2 nd responder(s): Agree or disagree with explanation. 3 rd responder: Summarize what all previous responders have said.

19. Discussion Questions Where can you find reactants and products in a chemical equation? How many of each type of atom were in the reactant side? How does that compare to the type of atom on the product side?

20. Discussion Questions What happens to the molecules on the reactant side to form the molecules on the product side? If you are given 4CO 2, how many: Carbon atoms are present? Oxygen atoms are present?

21. 3/5/2015 Catalyst: Suppose there had been no precipitation during 1 entire month of the 12-month period. Based on the information provided, during that month, there would have been: a.significant wet deposition of all 4 substances. b.significant wet deposition of Cu2+ and Zn2+, but no wet deposition of Cl- and SO42-. c.no wet deposition of Cu2+ and Zn2+, but significant wet deposition of Cl- and SO42-. d. no wet deposition of any of the 4 substances.

27. Catalyst: Is the statement “The values for Cl- were greater during the winter and early spring when road salt is typically applied” supported by the results of Study 2? a.Yes, because Cl - wet deposition values were, on average, greater from November to April than they were from May to October. b.Yes, because Cl - wet deposition values were, on average, less from November to April than they were from May to October. c.No, because Cl - wet deposition values were, on average, greater from November to April than they were from May to October. d.No, because Cl - wet deposition values were, on average, less from November to April than they were from May to October.
