Homework: LAB REPORT!!!!Objective: We will differentiate between physical and chemical changes.

Agenda• Catalyst• Paired Reading• Mini-Lab• Exit Ticket

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!

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.

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.

6 3/2 Lab: Signs of a Chemical Reaction

12

Agenda• Catalyst• Lab work – chemical changes• Discussion• Exit Ticket

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.

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.

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?

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. Cu2+

• b. Zn2+

• c. Cl-

• d. SO42-

Number6 3/4 Groupwork:

Introduction to Chemical Equations

13

Agenda• Catalyst• Discuss Lab from Monday• Groupwork: Intro to Chemical Equations• Discussion

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.

Discussion Protocol• 1st responder: Answer question with

explanation.• 2nd responder(s): Agree or disagree with

explanation.• 3rd responder: Summarize what all

previous responders have said.

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?

Discussion Questions• What happens to the molecules on the

reactant side to form the molecules on the product side?

• If you are given 4CO2, how many:• Carbon atoms are present?• Oxygen atoms are present?

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.

• 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.
