General Chemistry Syllabus
Course Description
Chemistry is the study of matter, the way in which particles of matter interact and the energy changes that occur. Laboratory investigations that include the use of scientific inquiry, research, measurement, problem solving, laboratory apparatus and technologies, experimental procedures, and safety procedures are an integral part of this course.
Academic Grades
Nine weeks grades will be weighted and calculated as follows:
- 50% Performance Grade Average*
- 15 % Quiz Grade Average
- 15% Assignment Grade Average
- 10% Participation Grade Average
- 10% Nine Week Test Grade
*A student must have a passing grade in Performance before the other grades will be averaged into the nine week grade. (If a student has an F in Performance, s/he has an F for the nine week grading period.)
Performance - Students are given a list of learning goals for each unit. Mastery of these goals can be shown through completion of lab activities, answering test questions, writing reports or completing projects. For complete mastery of a goal, the student will earn 4 points. Students may receive partial credit for each goal.
Quizzes – Students will have pop quizzes over homework or lab concepts. Scheduled quizzes over specific topics will also be given.
Assignments -This includes work done in class and homework assignments that are not learning goal assessments (performance grades). Homework is to be completed before coming to class and should be turned in to the assignment box when entering the classroom. Late homework will not be accepted. Students who have an excused absence on the date an assignment is given will be exempt from a grade for the assignment; students who have an unexcused absence will receive a “0” for the assignment. Any extra credit a student earns during the nine weeks is averaged into the assignment grade. Students may earn up to 50 points of extra credit each nine weeks.
Participation -Students can earn a maximum of 10 points each day for participation. Students will earn points if they are on time to class, cooperate and behave, work all period and bring to class their planner, paper, pen/pencil,notebook and word-up book. When students have an excused absence they will be exempt from a participation grade on that day. When students have an unexcused absence they will receive a “0” for a participation grade on that day. On days when a substitute is present,students must turn in their work to the assignment box or receive a “0” for participation for that day.
Nine Week Test - At the end of the nine week grading period, a test will be given on all the material covered during the nine weeks. The nine week test also provides an opportunity for students to improve their test grades.
Make-up Work - Students may make-up labs and tests missed due to an excused absence. Students have time equal to the number of days absent to make-up tests missed to due to an excused absence. The last day to make-up a lab missed due to an excused absence will be posted on the board but will be no more than two weeks. If you are absent, please check the assignment folder to see what you have missed in class and get the homework assignment. It is the student’s responsibility to make-up lab work and tests on time. Students may make-up work during lunch every day but Friday, during 4th or 5th period with teacher permission or after school on Monday, Wednesday or Friday.
Behavior and Class Procedures
As stated in the section on participation grades, students are expected to be on time to class, cooperate and behave, work all period and bring to class their planner, paper, pen or pencil,notebook and word-up book. When a student finishes class work for the day, s/he may work on an assignment from another class or read the word-up book until the rest of the class is finished.
Please respect yourself and the other students and teachers in the classroom. No put-downs are allowed, not even as a joke. Please watch your language; only school-appropriate language should be used in the classroom. Do not interrupt the speaker in the classroom; raise your hand and wait to be called on if you have a question, comment or answer for a question. Keep your desk and work area clean; throw garbage in the garbage can and paper in the recycling bin. Because we have restrooms in the classroom, you may use the restroom without asking permission.
Food and drink, except for clear water, are not permitted in class and paybacks will be given. No electronic devises except calculators are allowed in class. Cell phones should not be visible during class; students who have cell phones visible in class will receive a payback and the phone will be confiscated for the day.On the second cell phone offense, a parent will have to come to school to pick up the phone.
Cheating will not be tolerated. Cheating includes but is not limited to access to any test or quiz information whether written on paper, on your skin or clothing or any electronic device. A student in possession of any electronic device during a test or quiz will be assumed to be cheating. Any student caught cheating will receive a zero on the test or quiz and a payback. Parents will be notified.
Students should be ready to begin class when the bell rings. Materials for class should be on the table and backpacks stored. Students who have an excused tardy must bring a note which includes the student’s name, date and time and it must be signed by a staff member. Students will receive a payback on their third unexcused tardy in a nine week period and on any subsequent unexcused tardy during the nine week period. On the fourth unexcused tardy for the nine week period parents will be notified.
Conduct Grades
Conduct grades are based on a student’s attitude and behavior in class. The following criteria will be used toassign conduct grades:
- Shows respect to others.
- Cooperates and behaves in class.
- Works safely in labs.
- Participates in class discussions and activities.
- Comes to class prepared and on time.
