Prerequisites: Chemistry I Honors, Algebra II
GRADES: 11, 12
Rationale
ACC Chemistry is designed to be equivalent to a first-year college chemistry course, preparing the student for further
study in the physical or life sciences. . Foundational concepts from Chemistry 1 will be used as the starting point for
the study of acids and bases, solutions, kinetics, equilibrium, thermal, and electrochemistry. Advanced laboratory
experiences are included, and help students learn important aspects of the work of scientists, combining content with
inquiry and reasoning skills. Supplemental reading selections will be assigned to reinforce and establish connections
between chemistry and its application to solving practical problems throughout history. Emphasis will be placed on
developing effective communication skills with greater depth required in written work, and proper use of chemical
calculations will be stressed. Five (5) hours of Advanced College Credit are available through the University of
Missouri Saint Louis.
Goals-- Students taking this course will:
Gain a greater appreciation of the glory of God as they increase in understanding of his created order.
Become scientifically literate as they study the application of chemical knowledge to the solutions of critical problems
in history.
Gain a greater depth of chemical understanding relating to causes of reactions and behavior of chemical systems in
their environment.
Improve laboratory skills and apply inquiry processes to gain understanding.
Analyze experimental data, verify hypotheses, draw generalized conclusions about the system being studied, and to
predict its behavior.
Become effective communicators of their results and conclusions reached.

Format—
Class meets for 80 minutes a day, 5 days a week. A minimum of 20% of instructional time will be devoted to student
laboratory activities.
Requirements—
Regular class attendance and appropriate behavior.
Be prepared with paper, pencil, graph paper, and a simple scientific calculator.
Timely and neat completion of assigned work.
Strict observance of all established laboratory safety rules.
A bound laboratory notebook, to contain all supporting graphs, data tables, and conclusions, will be kept and be
returned to the student to assist placement in a college program.
Grading Policy-Performance will be based on a percentage of total points earned. Class grades will be based on the following types
of assignments, weighted as shown:
Quizzes and Tests
Lab Reports
Classwork / Participation
Supplemental Reading
55%
25%
10%
5%
Comprehensive Semester Exam = 15% of final semester grade
Letter Grades are assigned according to the following scale:
A
100 -– 93%
B
92 -- 85%
C
84 -- 76%
D
75 -- 70%
Assignments-Students can expect one quiz each week, based on material covered (so far) in that unit.
Laboratory work will be due no later than one week after the laboratory procedure is completed. Late work will
receive a 50% deduction; no credit will be given after reports have been returned, except in extenuating
circumstances. ** Students will work in groups, but each turn in their own report.
Homework is to be completed before the next class period after it is assigned. Since students are required to
present homework solutions on the board and explain calculations to the class, it is to the individual’s advantage to
have his work completed before class. Additionally, the tests and quizzes are drawn from the material in the
homework.
Supplemental reading assignments will be summarized, in paragraph form, around assigned questions focused on
the method behind chemical discoveries and their impact on society.

Laboratory Format
NOTEBOOK: You will maintain a bound notebook solely for experiments. It should be filled with graph paper and
contain at least 90 pages, with first two pages left blank for the index.
--Each lab report will start on a new page.
--Skip a line between sections of your report, and between calculations.
--Each section should have a title which is underlined.
--Use the lab manual as a guide for the title, introduction, calculations, and conclusions.
Your report should contain the following parts, in the following order:
TITLE:
Write full title of the experiment at the top of the first page of your report. Be sure to capitalize and include
the number of the experiment. This information will also be included on the index page of the notebook.
INTRODUCTION & BACKGROUND:
Here you will explain the ideas behind the experiment. Start with the purpose or objective of the experiment,
stated in one or two sentences. Include the hypothesis the experiment is designed to test. Then, explain the theory
behind the method you will use to accomplish the purpose, including major chemical reactions that will occur.
Remember, this is an overview, not a detailed procedure.
PROCEDURE & OBSERVATIONS:
A description of the procedure you followed, including the critical steps in the experiment. Also include
observations you made during the course of the procedure. Be sure to include the names & formulas of chemicals
you used and the equipment involved. Draw a picture of the apparatus.
DATA:
Make a data table to organize your data. Box in the data-- use a ruler to make straight lines. Write neatly
and include units on measurements with correct precision.
ANALYSIS / CALCULATIONS:
Show your calculations, including units. Place a title/ explanation beside each calculation. Remember, you
are trying to explain how you got your answer. This section will include any graphs required to explain the data
which must be on graph paper, titled, with axes labeled. Calculate the percent error (if applicable). Make sure you
answer any questions in the laboratory manual thoroughly, numbering and including the question in the answer.
CONCLUSIONS:
Explain what you have learned--your reasons should be based on the observations and measurements you
made while you were doing the experiment. Write your conclusions in complete sentences, including the following:
1) Using supporting details, explain how the hypothesis is or is not supported by the data.
2) Explain what you have learned by performing the experiment, giving evidence for each conclusion.
3) You should explain any differences between your results and the expected outcome with reasons based on
observations you made. Describe the specific errors you committed (in following the procedure) while in the lab, and
how they affect the outcome.
