Science Practice 4:The student can plan and implement data

AP Chemistry Syllabus
School year of 2013-2014
Course Description:
The Curriculum for AP Chemistry is representative of a first-year college Chemistry course.
Students will cover in depth a wide range of concepts important in the typical College
Chemistry classroom. Students will be challenged to develop critical thinking skills during
the course of this class. Laboratory experiments and analysis will be a very important
section of this course as well. Students will spend 25 % of the total instructional time in the
laboratory on hands-on laboratory work. Students will perform a minimum of 16 labs and
at least 6 of these labs will be inquiry –based labs.
There are 6 big ideas and 7 science practices that must be addressed in this course:
Big Idea # 1: The chemical elements are fundamental building materials of matter, and all
matter can be understood in terms of arrangements of atoms. These atoms retain their
identity in chemical reactions.
Big Idea # 2: Chemical and physical properties of materials can be explained by the
structure and arrangement of atoms, ions, or molecules and the forces between them.
Big Idea # 3: Changes in matter involve the rearrangement and/or reorganization of
atoms and/or the transfer of electrons.
Big Idea # 4: Rates of chemical reactions are determined by details of the molecular
collisions.
Big Idea # 5: The laws of thermodynamics describe the essential role of energy and explain
and predict the direction of changes in matter.
Big Idea # 6: Any bond or intermolecular attraction that can be formed can be broken.
These two processes are inn a dynamic competition, sensitive to initial conditions and
external perturbation.
Science Practices 1: The students can use representations and models to
communicate scientific phenomena and solve scientific problems.

phenomena and systems in the domain.

phenomena and systems in the domain.
1.4 The student can use representations and models to analyze situations or solve
problems qualitatively and quantitatively.
1.5 The student can re-express key elements of natural phenomena across multiple
representations in the domain.
Science Practice 2:The student can use mathematics appropriately.
2.1 The student can justify the selection of a mathematical routine to solve problems.
2.2 The student can apply mathematical routines to quantities that describe natural
phenomena.
2.3 The student can estimate numerically quantities that describe natural phenomena.

thinking or to guide investigations within the context of the AP course.
3.1 The student can pose scientific questions.
3.2 The student can refine scientific questions.
3.3 The student can evaluate scientific questions.

scientific question
4.2 The student can design a plan for collecting data to answer a particular scientific
question.
4.3 The student can collect data to answer a particular scientific question.
4.4 The student can evaluate sources of data to answer a particular scientific question.
Science Practice 5:The student can perform data analysis and evaluation of
evidence.
5.1 The student can analyze data to identify patterns or relationships.
5.2 The student can refine observations and measurements based on data analysis.
5.3 The student can evaluate the evidence provided by data sets in relation to a
particular scientific question.
Science Practice 6:The student can work with scientific explanations and theories.
6.1 The student can justify claims with evidence.
6.2 The student can construct explanations of phenomena based on evidence produced
through scientific practices.
6.3 The student can articulate the reasons that scientific explanations and theories are
refined or replaced.
6.4 The student can make claims and predictions about natural phenomena based on
scientific theories and models.
6.5 The student can evaluate alternative scientific explanations.
Science Practice 7:The student is able to connect and relate knowledge across
various scales, concepts, and representations in and across domains.
7.1 The student can connect phenomena and models across spatial and temporal scales.
7.2 The student can connect concepts in and across domain(s) to generalize or extrapolate
in and/or across enduring understandings and/or big ideas.

Grading:
Students’ grade will be calculated from the following:
Test and quizzes: 50% of the total grade. The format of the test will be similar to the
format of the AP exam.
Midterm and Final Exam: 20% of the total grade.
Lab activities/ Lab reports: 20% of the total grade. Students will be expected to
participate in group lab experiments and to write individual lab reports in a composition
notebook. The lab report must include title, purpose, materials, procedures, Pre-lab
questions (if applicable), data, graphs, data analysis, conclusions, discussion of theory,
sources of error and post-lab questions.
Homework: 10% of the total grade. Students will be expected to complete homework
assignments at home. In order for students to receive credit for the homework assignment
the homework must be turned in at the beginning of each class period. Students will be
expected to be prepared to share and discuss answers to their assignments in class for
class discussion. Students are expected to show all of their work for the calculations.
Make up work:
Students who have excused absences will have the number of days missed plus an
additional day to turn in missed assignments. Test or quizzes missed must be made up
during the next available ESS session. It is the responsibility of the student to contact the
teacher before or after school to ask for missed assignments. No late work will be graded.
Students with excused absences will have to do an alternative assignment during ESS or
Saturday School because chemicals have to be tossed after a certain period of time.
Parents please encourage your child to attend class on the regular basis. Students who
come to class regularly do better than students who have a lot of absences. Please try to
schedule doctor’s appointments, college visits and other types of appointments after school
if at all possible.
Study Suggestions/ Strategies for Success:
1. Be willing to put effort and time: Just putting in time in the classroom alone is not
enough to do well in this class. Students must be willing to spend time outside the
classroom to devote AP Chemistry (about 1-2 hours a day). Students should give
their best effort to try to grasp some of the difficult concepts that we have to cover
in this class.
2. Practice, Practice, Practice: In order for students to master a skill practice is
imperative. If you were a basketball player you would not give up playing
basketball just because you missed the first basket. Instead you would to go the
gym and practice shooting the basketball several times until you managed that skill.
Same principle applies here, you can get the skill if you are willing to practice.
3. Be a team player: You can learn a great deal of information from your peers. Let’s
create an atmosphere in which we help one another and encourage one another
instead of competing against each other. We can get a lot more accomplished that
way.
4. Become a self-learner: Remember with the large curriculum that we have to cover
and the limited amount of time I can’t possibly teach you all you need to know so
you need to learn to rely not only on what you can learn on your own but also on
what you can learn from your peers.
Availability for Extra Help:
I will offer help sessions every Tuesday and Thursday from 7:55 to 8:25 for students who
need extra help, would like to check their homework with me before class or to study for a
test or quiz.
I strongly suggest that if you find yourself struggling in this class that you take advantage of
these help sessions. I also strongly suggest that you form study groups with your peers to
help one another learn and study.
