Course Description
The AP Chemistry course at Granbury High school emulates the first year of college chemistry in breadth and rigor. The
goal of this course is to prepare the student to become an independent thinker functioning in a scientific, technological
society with an appreciation for the natural world. Through discussions, lecture, and laboratory experimentation, the
aim of AP Chemistry is to sharpen the student’s ability to think critically, solve problems and communicate effectively.
The student will be expected to demonstrate development of these abilities through completing assignments, class
presentations, assessments, informal and formal written reports and ultimately an acceptable score on the AP Chemistry
Examination in May.

Requirements and Expectations
Students are expected to be in class on time with the required materials. The AP Chemistry class meets five 55-minute
periods each week.
To be successful in this class, it will be necessary for students to study and practice problems in chemistry outside of
class, at the very least, one hour per day. Homework assignments will be assigned to provide students with
opportunities for study and practice. Most of the time, homework will not be graded. Mastery of process skills and
concepts will be assessed based on performance on quizzes and tests. The AP chemistry student is expected to seek help
outside of class if he/she is struggling with a particular concept or problem-solving process. I will be available before and
after school if a student needs help or needs a quiet place to work. I have an open-door policy to all my students, so it is
advised NOT to wait until the day an assignment is due or the day before a test to get help.
In each laboratory experiment, students will physically manipulate equipment and materials, make observations, collect
and analyze quantitative and qualitative data, use the data to form conclusions and verify hypotheses. Also, students
will communicate and compare lab results and procedures through collaboration, presentations, and formal written
reports. Students will be expected to keep a formal laboratory notebook. Each student will be provided with a carboncopy lab notebook. The lab experiments will come from sources equivalent to labs encountered in a first-year college
chemistry course. Approximately 1-2 periods per week will be devoted to time in lab; however, students will be required
to spend time outside of class time in the lab completing practical portions of labs and data collection in many cases.
Test and quiz corrections are encouraged for all students, but are required for any student making a failing grade on an
exam. Points will be awarded on the test grade for corrections completed correctly.
Grading Guidelines
Minor Grades
Daily work
Homework and daily work is self-checked and may sometimes count as a minor grade. It is expected to be on
time, and any late work will only be granted half credit.
Laboratory grade
Labs will be graded with each lab and count as one or two minor grades. Lab work is assessed in many ways,
such as formal/informal lab reports and class presentations of data and results. Any late reports will be docked
10 points per day late.
Quizzes
Quizzes count as a minor grade, and are designed for students to spot areas that need special attention before a
major exam.
Major Grades
Tests
Major tests will count as a major grade. The tests will follow the AP exam format, and questions will come from
previously released AP exams. Generally, students can expect an exam 2-3 times per six-weeks depending on
material being covered.
Projects
Projects may count as two minor grades or one major grade depending on the nature of the project.
