Students will be able to recall information from semester one through performing practice questions with partners.

Chemistry is a complex area of study and it is crucial to spend time reviewing previously learned concepts prior to the final exam.

This lesson serves as a review of first semester through performing practice multiple choice questions with partners.

Because students are reviewing first semester this lesson touches on various performance expectations including:

:**HS-PS1-1***Use the periodic table as a model**properties of elements based on the patterns of electrons*in the outermost energy level of atoms.:**HS-PS1-2***Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.*:**HS-PS1-3***Plan and conduct an investigation to gather evidence**to compare the structure of substances at the bulk scale to infer*the strength of electrical forces between particles.:**HS-PS1-7***Use mathematical representations to support the claim**that atoms, and therefore mass, are conserved*during a chemical reaction. .

In this section of the lesson I introduce to students the goal of the lesson, "The goal of today's lesson is to review for our final exam through performing practice multiple choice questions with partners"

I make sure that students have the review packet and have them turn to the last page where I have a space for partner review appointments.

I then have students make partner appointments (*see reflection on partner appointments for more details*).

70 minutes

In this section students are working with their partners to complete questions. I have students do several multiple choice questions with each of their partners. I choose questions that I know are confusing for students or ones that are time consuming so that they are more likely to complete when doing in class. This is the list of appointments and the questions I have students perform:

Appointment 1- Questions: Unit 1 (6,7,11)

Appointment 2- Questions: Unit 2 (2,4,8,16)

Appointment 3- Questions: Unit 2 (23,25,26,27)

Appointment 4- Questions: Unit 3/4 (4,8,10,14)

Appointment 5- Questions: Unit 3/4 (17,23,26,31)

Appointment 6- Questions: Unit 5 (4,6)

Appointment 7- Questions: Unit 5 (8,9)

After each appointment I take one student's paper and spend a few minutes reviewing the answers. If a student does not have a correct answer I expect them to correct on their paper and ask questions if they do not understand why they got the incorrect answer. This video Reviewing questions in partner practice shows me going over answers to appointment #2 with students. Notice how I correct this student's answer as I am explaining.

After I have reviewed the answers with students I have them thank their partners and move to the next appointment. This Switching partners movie shows how I do this with students moving from partner #2 to partner #3 and then I give them the questions to complete with their next partner.

This is one student"s filled in paper.

20 minutes

For the last part of the lesson I have students continue to work on the practice questions either by themselves or with partners of their choice. I let students know that this packet will be due the day before the final at which point I will check for completion and staple an Answer Key to the packet for them.

The reason I give the answer key is that this allows me the time where I do not have to go over every answer in class, but students can check their own answers.

During the class where I check the packet for completion and give out answer keys I also give time for students to ask questions concerning the problems, especially ones which they got wrong.
