This document provides a year-long plan for a chemistry class offered to sophomores and juniors. The plan incorporates 14 units taught over the school year, with 7 units before winter break and 7 after. Each unit ends with a review day and test. There is also a mid-year cumulative exam after Unit 7 and an end of year exam after Unit 14. Buffer time is allocated for units running long or for optional additional units on hydrocarbons, life chemistry, or nuclear chemistry.

1. Year-Long Plan: Chemistry
This year-long plan represents a Chemistry class that would be offered to sophomores and juniors
at a high school in the Columbus City School District. Dates in this plan are estimated based on the
Columbus City School calendar for the 2014-2015 school year. In this plan, I estimated three snow days,
two assembly days, two weeks of state testing, two SAT/ACT testing days, and two PD days. Days when
there is no school are shaded in dark green and days when there is reduced instruction time are shaded in
light green. The planned progression of units is a combination of the Arizona State Modeling Curriculum
that I plan on using in my future classroom and the Columbus City School Pacing Guide and Content
Alignment. I have made some modifications in the order of units since students do not take a state or
graduation test for Chemistry.
This year-long plan incorporates 14 separate units. Seven will be covered before winter break
and seven will be covered after winter break. Each unit ends with one review day and one test day. Tests
are scheduled for either Wednesday or Friday and never occur after a break. Unit 5 ends on the same day
as the end of a grading period, but it would be explained to students that grades for that unit would be
included in the 2nd
grading period rather than the 1st
. All other units end at least two days before the end
of a grading period. After Unit 7 and Unit 14 there will also be a Cumulative Exam that covers the
previous 7 units. This exam can be used as either a make-up test for students who missed a unit test, or
extra credit to replace their lowest test score.
Unit Outline
First three days of school: These days will be spent covering student, teacher,and class introductions.
After this, we will do a content introduction activity and a review of lab safety. Student should be
introduced to lab protocols and procedures.

Unit 6 – Internal structure (20 days total)
This unit is larger and covers more topics. I have split the unit into three smaller sections with a quiz at
the end of each section rather than a test. At the end of Unit 6, students will take their cumulative exam.
This exam will focus mainly on Unit 6 rather than having a separate test devoted to Unit 6 alone.
Unit 6.1 – Atomic Structure (Allotted Time: 8 days)
o Review parts of the atom, charges,and the Thompson cathode ray experiment (2 days)

Unit 6.3 – Chemical Names and Formulas (Allotted Time: 8 days)
o Naming binary ionic compounds (3 days)
o Giving formulas for ionic and molecular compounds (3 days)

Review of Unit 6 (1 day)
Mid-year Cumulative Exam (1 day) – This test will be offered to students as either a make-up test for
missed tests or an extra credit exam to replace their lowest test score. The exam will focus mainly on
Unit 6 topics to help sum everything up, but will also include other topics from the year. The aim of this
exam is to help students build and add to their knowledge instead of learning units in isolation and then
forgetting about them.
6.5 days (yellow on the calendar) of buffer space - I plan on using this time to compensate for units that
take longer than planned. If this is not necessary then I plan on using the time to review past topics so
that students are ready to move on to chemical reactions. If there is still significant time left over before
winter break, then I may supplement with one of the three possible “Additional Units” that will be
detailed at the end. They include Hydrocarbons, Life Chemistry, and Nuclear Chemistry.

End of Year Cumulative Exam: This will be a cumulative exam that covers the second half of the year
(Units 7-14). It will be a make-up or extra credit test opportunity for students much like the Mid-Year
exam.
Potential time at the end of the year (There are three extra days indicated on the calendar): This time is
allotted for the following possibilities:
1. The previous units took longer than expected and overflow into this time
2. Three potential “Additional Units” could be covered depending on student interest.
a. Unit 15 – Hydrocarbon Compounds
i. Combustion reactions
ii. Polymers
iii. Fossil fuels
b. Unit 15 – Life Chemistry
i. Cellular Respiration
ii. Biological Molecules
c. Unit 15 – Nuclear Chemistry
i. Types of radiation
ii. Radioisotopes
iii. Radioactive Decay
iv. Fission, Fusion, and Energy Considerations
