AP Chemistry Syllabi/Prospectus
2015-2016
Mr. Niedenzu
AP/IB Exam Policy:
As you are aware, CMS pays the exam fee for students to take AP and IB exams
- Students must take the AP exam or take a teacher made exam at the end of the year that will count as 20% of their final grade
Overview: The AP Chemistry course meets daily for one 90 minute period. Labs are conducted during the week on alternating days. This course is designed to provide a solid, first-year college chemistry experience, both conceptually and in the laboratory. The labs serve to supplement the learning in the lecture section of the course. Problem-solving skills, both on paper and in the lab, are emphasized. There are weekly labs and during the last quarter three full practice AP tests are taken and graded according to AP grading scale.
Laboratory: Students are required to submit a complete report for each lab experiment, including a hypothesis, procedure, observations/data, calculations, sources of error, and a conclusion. All reports are kept in a lab notebook. The students are also called upon to make a presentation to the class about their hypotheses, calculations, and conclusions – in this way students can collaborate on the objectives and design of an experiment, and assist each other in reaching conclusions, and gain insights into variance and sources of error. Lab descriptions are listed at end of syllabus after the resources.
Reaction sets: Are no longer part of the AP exam specifically but a good knowledge thereof is essential to answer some questions.
Class rules
Students need to have access to the internet to access my website and other resources we will use during the year.
Cell phone use is not allowed during the school day – if I see it or hear it, it will be confiscated and turned in to the front office.
No food is allowed in class. Only clear, colorless water bottles containing water will be permitted.
Cheating will not be tolerated.
Late work will have a letter grade deduction for each day late (unless there is some extenuating circumstance).
Behavior issues will be dealt with “in house” – the administration has many other things to deal with and I will handle these issues as they arise. Also, be forewarned, I DO call parents at home and at work, and I will call you at home if you have been absent or are absent to check on things.
Required materials:
materials for taking notes
scientific or graphing calculator
graph paper
colored pencils
Absences: I will follow the CMS guidelines on absences, please recheck your handbook on this.
If you are absent and want to stay current – email me immediately at school
I will respond immediately!!!
Lab safety:
All students will undergo a review of lab safety rules and have to sign (along with the parents) that they have read the safety rules, watched the safety video, know where all the safety equipment in the room is located and the proper way to use it.
Homework:
I do not assign a lot of homework at once – the problems I do assign are carefully selected – some of the assignments are already on my web page, some will have answers with the questions.
Assignments/quizzes:
BEWARE: I will give short quizzes in class almost every day!!! I do give retakes on these if needed.
Missed assignments:
CMS allows you 5 days to schedule a time/due date to turn in missed assignments – remember it is your duty to take care of this!
Grades:
I operate on the point system and generally most classes will have over 1000 points accumulated for each quarter. Assignments will be listed as either formal (70% of the quarter grade) or informal (30% of the quarter grade) I will follow CMS guidelines on grade distribution which this year is on a ten point scale where 100-90 is an A, 89-80 is a B, 79-70 is a C, 69-60 is a D, below 60 is an F. Point distribution is as follows:
Quizzes: anywhere from 5 – 20 points
Homework: from 10 – 20 points
Lab reports: from 20 – 50 points
Tests: from 30 – 70 points
We will go over lab report format in class – be aware that this area is usually where many student’s grades suffer because they do not turn in reports on time! In general you will have a week to turn in reports after the lab is done.
Tutoring:
The chemistry department will have weekly scheduled tutoring availability – the schedule will be given to you during the first week of school. In the fall I have limited availability for tutoring due to coaching responsibilities. In the winter and spring I will be available after school each day for help. Before school is an option this year since I have first block planning all year.
