COURSE PREREQUISITES: Algebra 2, Physical/Earth Science
COURSE DESCRIPTION: This course teaches the nature of matter, matter’s chemical
and physical properties, chemical bonding, chemical reactions and equilibrium,
chemical quantities and solutions, acids, bases, and buffers, and oxidation-reduction
chemistry. The objective of the course is to build on the student’s existing knowledge
of chemistry, to explore chemistry as it applies to examples in and out of the
classroom, and to integrate chemical principles with other areas of science including
physics, biology, environmental science, biochemistry, and chemistry in society.. A
scientific calculator is required for this course. The calculator should have an
exponent key (EE or EXP) and a log key (LOG). The math prerequisite for this
course is Algebra 2 (or taken concurrently with this course).
COURSE OBJECTIVES (The objectives for the LAB COMPONENT of Chemistry

Requirements and Expectations for Class
1. Students are expected to bring to class: textbook, laboratory notebook, pencil or pen, and
when requested a scientific calculator with an EE key and a LOG key.
2. Students are expected to make up work in a timely fashion.
3. Homework assignments, lab reports, pre-labs and post-labs are due on the assigned date.
4. Students are expected to show respect and responsibility during class time.
5. Attendance is very important. The student will be at a distinct disadvantage when a
topic is missed – it will be his or her responsibility to make up missed class work.
6. Homework is very important to understanding chemistry concepts. AP Lab Experiments will
require preparing a pre-lab in your journal to identify disposal and safety consideration.
The procedure for the lab experiments should be pre-read and recorded in your journal in your
own words. It is essential that students complete the pre-lab to obtain an understanding of
logistics and safety aspects of the experiment.
7. Make-up for missed experiments can be completed at a time pre-arranged between student and
instructor.
Expectations for Students Absent from Class
Students are advised that absence does not excuse them from meeting course
requirements. All written assignments are to be submitted the day they are due.
 If an emergency arises, and a student must be absent from class, the student is
requested to send an e-mail before class begins with attached assignments that are
due that day.
 A student may e-mail assignments (if absent) by midnight the day of class without
having a letter grade deducted from that assignment. In addition, the student must
provide the instructor with a hard copy of the assignment at the next class. The
instructor is not responsible for printing out student assignments.
 If a student missed a class and has late work, the student assumes the
responsibility to make arrangements with the instructor when and where the
makeup work will take place.
6

If a student knows of an upcoming absence, the student must conference with the
instructor (before the absence) for work that will be assigned.
Note on laboratory investigations – AP Experiments:
All labs listed, activities and experiments, are conducted by students - usually in lab
groups of three. The AP laboratory experiments are borrowed largely from the Flinn
Manual for AP Chemistry Experiments. Each experiment introduces at least one new
concept (usually more than one) and it’s the student’s goal through the investigation to
grasp the concept(s) after collecting the data and writing a post-lab to the investigation.
Students are required to keep a separate laboratory journal. Before the experiment is
conducted, students are asked to do a pre-lab - this involves reading over a copy of the
laboratory procedure and rewriting the procedure in their laboratory journal in their own
words. The pre-lab includes the title of the lab, date, objective or objectives, materials,
chemicals and equipment, safety and disposal considerations, and the students own
interpretation of the laboratory procedure in a step-by-step approach so that the student
will be able to conduct the experiment successfully without the original copy of the lab
procedure. The pre-lab should also include room for data collection and/or expected
observations. For example, if the experiment involves conducting a titration, then the
student should have a prepared data table in their journal to collect the titration data.
After the investigation is complete, students are asked to analyze their data. I will either
prepare instructions for analysis of data, or ask the students to follow the discussion
questions as outlined in the original procedure. To complete the post-lab, the student
analyzes the data according to guided questions provided, carries out necessary math
calculations, calculates a percent error if the experiment involves a quantitative analysis,
and identifies at a minimum three sources of error. The student is also asked to conclude
the post-lab with five new ideas the student can take away from the lab – the new
ideas/applications should be a reflection of the objective(s) of the lab. The completed AP
Experiments (as noted in the WEEKLY READINGS/LAB ASSIGNMENTS/EXAM SCHEDULE above)
are worth 25 points. Non-AP Experiments are worth 10 points.

Rubric for Post-lab Write-ups (AP Labs)
The following grading scheme for post-lab write-ups will be used for evaluation.
4 The lab write-up includes a completed pre-lab Title, Objective(s), Materials,
student’s interpretation of the Laboratory Procedure, room for observations or
a data table, safety and disposal considerations. The post-lab includes an
analysis section (section that evaluates the observations or data collected), the
observations and/or data are interpreted correctly and thoroughly tying the objective(s)
to the results of the experiment. Equations or chemical formulas are used to help
with explanations during evaluation. When necessary, mathematical calculations
are shown to interpret results. When the investigation is a quantitative analysis,
a percent error is completed, is accurate, and a minimum of 3 sources of error are
identified. Conclusions are drawn from the evaluations section (5 new ideas that the
student learned) that demonstrate the student has a good understanding of the
7
objective(s) of the lab and can now apply them.
Note: Since post-labs are worth 25 points, the actual score of the post-lab will be weighed
on thoroughness and accuracy. A score of a 4 can actually lead to a possible point score
of 25-22 depending on attention to detail of the sections mentioned in the explanation
above.
3 The lab write-up should include a completed pre-lab Title, Objective(s), Materials,
student’s interpretation of the Laboratory Procedure, room for observations or
a data table, safety and disposal considerations. One or more of these sections may
have been left out. The post-lab includes an analysis section (section that evaluates the
observations or data), the observation and data are interpreted but the understanding
may be correct in some cases but vague or incorrect in others. One or more
of the opportunities for evaluation may have been only mentioned or left out. The
student attempts to tie the objective(s) during the evaluation of results. Equations or
chemical formulas are used in part to help with explanations during evaluation. When
necessary, mathematical calculations are shown to interpret results. When the
investigation is a quantitative analysis, a percent error is completed, but may not be
accurate, and less than 3 sources of error are identified. Conclusions are drawn from
the evaluations section (5 new ideas that the student learned) that demonstrate the
student has a good understanding of the objective(s) of the lab but one or more
conclusions is not clear, or is not tied in with the objective(s).
Note: Since post-labs are worth 25 points, the actual score of the post-lab will be weighed
on thoroughness and accuracy. A score of a 3 can actually lead to a possible point score
of 21-18 depending on attention to detail of the sections mentioned in the explanation
above.
2 The lab write-up does not include a completed pre-lab Title, Objective(s), Materials,
student’s interpretation of the Laboratory Procedure, room for observations or
a data table, safety and disposal considerations, or includes only part of these sections.
The pre-lab has no mention of safety and disposal considerations. The post-lab
includes an analysis section (section that evaluates the observations or data), the
observations and data are interpreted but the understanding is not correct or consistent
as one idea is discussed after the next. One or more of the opportunities for evaluation
may have been only mentioned or left out. The student through their discussion does
not have a clear idea of the objective(s) of the laboratory procedure. Equations or
chemical formulas are used in part to help with explanations during evaluation, but one
or more have been left out. When necessary, mathematical calculations are shown to
interpret results but the math or interpretation is not correct. When the investigation is
a quantitative analysis, a percent error is completed, but is not accurate, and less than 3
sources of error are identified. Conclusions are drawn from the evaluations section (5
new ideas that the student learned) that demonstrate the student has a good
understanding of the objective of the lab but two or more conclusions are not clear, or
are not tied with the objective(s).
Note: Since post-labs are worth 25 points, the actual score of the post-lab will be weighed
on thoroughness and accuracy. A score of a 2 can actually lead to a possible point score
8
of 17-14 depending on attention to detail of the sections mentioned in the explanation
above.
Long-term assignments are assignments of more than five days in duration. Failure to
hand in work by the last acceptable due date will result in a grade reduction of 10% per
day.
