Section IV: Grading Policy

I. Components of the Marking Period Grade

a. Summative Assessments (80% of Marking Period Grade)

i. Marking Periods 1, 2, and 3 – during each marking period, four (4) summative unit

exams will be given to assess student understanding. Each of these unit exams will be

weighted equally in the marking period grade. All exams are cumulative and may draw

upon any material that has been previously covered in the course.

ii. Marking Period 4 – during the fourth marking period, shorter review quizzes and/or

simulated A.P. Exams will be given in place of unit exams. Unit exams may also be given

on material that is covered after the A.P. test, as time permits. Together these assessments

will constitute the summative portion of a student’s fourth marking period grade.

b. Formative Assessments (20% of Marking Period Grade)

i. Laboratory – lab assignments will typically assess a student’s ability to accurately analyze

data, identify sources of error, and draw conclusions. Some labs may also include

performance based components as part of the grade. All work will be submitted through

the Schoology course page. Late work will not be accepted.

ii. Homework and Classwork – homework and classwork may be included in the formative

portion of the grade for each marking period. Not all assignments will be formally graded

by the instructor, however the solutions to all assigned work will be reviewed in class

and/or provided on Schoology for students to review. Late work will not be accepted.

II. Calculation of Final Grades − the final grade for the course will be calculated using a weighting of twenty

percent for each marking period and twenty percent for the final exam, as summarized in the table below.

III. College Level Expectations – The accelerated pace and level of difficulty involved in mastering two

semesters of college chemistry content will require a serious commitment from each student. Students in

A.P. Chemistry will be held to higher expectations that they would in a typical high school course. The

following policies will be in effect throughout the course:

a. I will not accept late work.

b. I will not allow test retakes.

c. I will not curve test grades.

d. I will not curve marking period grades.

e. I will not offer extra credit assignments.

Section V: Course Policies

I. Absence Policy - if a student is absent, it is his or her responsibility to obtain all make-up work, including

any class notes. For excused absences, the student will have one day for every day absent to make up the

missed work as per the Appoquinimink School District attendance policy. Make-up work that is not

completed within the allotted time frame will be assigned a grade of zero.

II. Use of Electronic Devices - all students are expected to have their Chromebook available for use in class

on a daily basis. Cell phones and other electronic devices are not to be used during class time. A cell

phone is not an acceptable substitute for a calculator and may not be used as such. When an exam is

administered, cell phones, Chromebooks, and other electronic devices may not be used and should remain

out of sight. Any unauthorized usage of an electronic device during an exam will be treated as an act of

academic dishonesty and will result in the student receiving a grade of zero on the assessment.

III. Academic Dishonesty - any student who participates in an act of academic dishonesty will receive a score

of zero on the assignment in question and may also be subject to disciplinary action. As described in the

Student Code of Conduct, academic dishonesty includes “Fraudulent deception in preparing, or presenting

coursework or class assignments as a student’s own work when it is not. This includes, but is not limited to:

(1) copying another student’s work, (2) unauthorized use of notes or sharing answers during a test, (3)

presenting another person’s work as one’s own, or (4) presenting quotations, words or ideas without proper

references or credit.”

Appendix A: Overview of Course Content

Section I: The Big Ideas

The big ideas serve as the foundation of the course and allow students to create meaningful connections among

concepts. They are often abstract concepts or themes that become threads that run throughout the course. Revisiting

the big ideas and applying them in a variety of contexts allows students to develop deeper conceptual

understanding. Below are the big ideas of the course and a brief description of each.

Big Idea 1: Scale Proportion and Quantity

Quantities in chemistry are expressed at both the macroscopic and atomic scale. Explanations, predictions, and

other forms of argumentation in chemistry require understanding the meaning of these quantities, and the

relationship between quantities at the same scale and across scales.

Big Idea 2: Structure and Properties

Properties of substances observable at the macroscopic scale emerge from the structures of atoms and molecules

and the interactions between them. Chemical reasoning moves in both directions across these scales. Properties are

predicted from known aspects of the structures and interactions at the atomic scale. Observed properties are used to

infer aspects of the structures and interactions.

Big Idea 3: Transformations

At its heart, chemistry is about the rearrangement of matter. Understanding the details of these transformations

requires reasoning at many levels as one must quantify what is occurring both macroscopically and at the atomic

level during the process. This reasoning can be as simple as monitoring amounts of products made or as complex as

visualizing the intermolecular forces among the species in a mixture. The rate of a transformation is also of interest,

as particles must move and collide to initiate reaction events.

Big Idea 4: Energy

Energy has two important roles in characterizing and controlling chemical systems. The first is accounting for the

distribution of energy among the components of a system and the ways that heat exchanges, chemical reactions, and

phase transitions redistribute this energy. The second is in considering the enthalpic and entropic driving forces for

a chemical process. These are closely related to the dynamic equilibrium present in many chemical systems and the

ways in which changes in experimental conditions alter the positions of these equilibria.

Section II: The Science Practices

The AP Chemistry science practices describe what a student should be able to do while exploring course concepts.

The table that follows presents these practices, which students should develop during the AP Chemistry course.

These practices are categorized into skills, which form the basis of the tasks on the AP Exam.

Practice 1: Models and Representations – describe models and representations, including across scales

Practice 2: Question and Method – determine scientific questions and methods

Practice 3: Representing Data and Phenomena – create representations or models of chemical phenomena

Practice 4: Model Analysis – analyze and interpret models and representations across scales

Practice 5: Mathematical Routines – solve problems using mathematical relationships

Practice 6: Argumentation – develop an explanation or scientific argument.

Appendix B: Laboratory Safety

Appoquinimink School District

Science Safety Rules and Contract for Secondary Students

PURPOSE

Science is a hands-on laboratory class. You will be doing many laboratory activities which may require the use of

potentially hazardous materials. Safety in the science classroom is the #1 priority for students, teachers, and

parents. To ensure a safe science classroom, a list of rules has been developed and provided to you in this student

safety contract. These rules MUST be followed at all times. Two copies of the contract are provided. One copy

must be signed by both you and a parent or guardian and returned to your classroom teacher before you can

participate in any activity. The second copy is to be kept as a constant reminder of the safety rules.

As with any school activity, disruptive behavior during science labs falls under the Appoquinimink School District

Student Code of Conduct.

GENERAL RULES

1. Follow all written and verbal instructions carefully. If you do not understand a direction or part of a

procedure, ask the instructor before proceeding.

2. Never work alone. No student may work in the laboratory without an instructor present.

3. When first entering a science room, do not touch any equipment, chemicals, or other materials in the

laboratory area until you are instructed to do so.

4. Perform only those experiments authorized by the instructor. Never do anything in the laboratory that is

not called for in the laboratory procedures or by the instructor. Carefully follow all instructions, both

written and oral. Unauthorized experiments are prohibited.

5. Observe good housekeeping practices. Work areas must be kept clean and tidy at all times. Bring only

your laboratory instructions, worksheets, and/or reports to the work area. Other materials (books, purses,

backpacks, etc.) will be stored in a designated area.

6. Know the locations and operating procedures of all safety equipment including the first aid kit, eyewash

station, safety shower, fire extinguisher, and fire blanket. Know where the fire alarm and the exits are

located.

7. Know what to do if there is a fire drill during a laboratory period; containers must be closed, gas valves

turned off, fume hoods turned off, and any electrical equipment turned off.

8. Be alert and proceed with caution at all times in the laboratory. Notify the instructor immediately of any

unsafe conditions you observe.

Page 10: A.P. Chemistry Syllabusappohigh.enschool.org › ourpages › auto › 2019 › 9 › 9... · Marking Period 4 – during the fourth marking period, shorter review quizzes and/or

9. Dispose of all chemical waste properly. Never mix chemicals in sink drains. Sinks are to be used only for

water and those solutions designated by the instructor. Solid chemicals, metals, matches, filter paper, and

all other insoluble materials are to be disposed of in the proper waste containers, not in the sink. Check the

label of all waste containers twice before adding your chemical waste to the container.

10. Keep hands away from face, eyes, mouth and body while using chemicals. Wash your hands with soap and

water after performing all experiments. Clean all work surfaces and apparatus at the end of the experiment.

Return all equipment clean and in working order to the designated area.

11. Students are never permitted in the science storage rooms or preparation areas unless given specific

permission by their instructor.

12. If you have a medical condition (e.g., allergies, pregnancy, etc.), check with your physician/school nurse

prior to working in lab.

13. Handle all living organisms used in a science activity in a humane manner.

CLOTHING

14. Any time chemicals, heat, or glassware are used, students will wear laboratory goggles. There will be no

exceptions to this rule!

15. Contact lenses should not be worn in the laboratory unless you have permission from your instructor.

16. Dress properly during a laboratory activity. Long hair, dangling jewelry, and loose or baggy clothing are a

hazard in the laboratory. Long hair must be tied back and dangling jewelry and loose or baggy clothing

must be secured. Shoes must completely cover the foot.

ACCIDENT AND INJURIES

17. Report any accident (spill, breakage, etc.) or injury (cut, burn, etc.) to the instructor immediately, no matter

how trivial it may appear.

18. If a chemical splashes in your eye(s) or on your skin, immediately flush with running water from the

eyewash station or safety shower for at least 20 minutes. Notify the instructor immediately.

HANDLING CHEMICALS

19. All chemicals in the laboratory are to be considered dangerous. Check the label on chemical bottles twice

and take only as much as you need. Do not touch, taste, or smell any chemicals unless specifically

instructed to do so. The proper technique for smelling chemical fumes will be demonstrated to you.

20. Never return unused chemicals to their original containers.

21. Acids and bases must be handled with extreme care. You will be shown the proper method for diluting

strong acids and bases.

22. Never remove chemicals or other materials from the laboratory area.

Page 11: A.P. Chemistry Syllabusappohigh.enschool.org › ourpages › auto › 2019 › 9 › 9... · Marking Period 4 – during the fourth marking period, shorter review quizzes and/or

HANDLING GLASSWARE AND EQUIPMENT

23. Never handle broken glass with your bare hands. Use a brush and dustpan to clean up broken glass. Place

broken or waste glassware in the designated glass disposal container.

24. Examine glassware before each use. Never use chipped or cracked glassware. Never use dirty glassware.

25. Do not immerse hot glassware in cold water; it may shatter.

26. When removing an electrical plug from its socket, grasp the plug, not the electrical cord. Hands must be

completely dry before touching an electrical switch, plug, or outlet.

27. Report damaged electrical equipment immediately. Look for things such as frayed cords, exposed wires,

and loose connections. Do not use damaged electrical equipment.

28. If you do not understand how to use a piece of equipment, ask the instructor for help.

HEATING SUBSTANCES

29. Exercise extreme caution when using a gas burner, hot plate, and candle. Take care that hair, clothing and

hands are a safe distance from the flame at all times. Do no put any substance into the flame unless

specifically instructed to do so. Never reach over an exposed flame. Light gas (or alcohol) burners only as

instructed by the teacher.

30. Never leave a lit burner, hot plate, or candle unattended. Never leave anything that is being heated or is

visibly reacting unattended. Always turn the burner or hot plate off when not in use.

31. You will be instructed in the proper method of heating and boiling liquids in test tubes. Do not point the

open end of a test tube being heated at yourself or anyone else.

32. Heated metals and glass remain very hot for a long time. They should be set aside to cool and picked up

with caution. Use tongs or heat-protective gloves if necessary.

33. Never look into a container that is being heated.

34. Do not place hot apparatus directly on the laboratory desk. Always use an insulating pad. Allow plenty of

time for hot apparatus to cool before touching it.

Chemistry Addendum to Appoquinimink School District
