Step 1: Between the start of your school year and the AP Chemistry Exam (usually early May) you must develop a plan to cover a full year of college-level Chemistry – including the AP recommended labs. It starts with pulling out your school calendar. What I like to do is block out all Sundays, holidays, no class days (block scheduling), and … notice I do not block out Saturdays. These may be used for review and labs. What you should be left with are the ‘teaching’ days that you have between the start of school and the exam.
Step 2: Next decide the sequence that you want to teach. Traditionally, you follow the textbook/flash drive that you have. Begin with Chapter 1 and plan to go thru the chapters that the author has laid out. This approach has been successful for many teachers and their students.
Alternatively, a new approach has been growing in popularity. After beginning with the Gas Laws, do the second half of your book first.
Let me give you the sequence of each:
| Traditional | Alternative |
|---|---|
| Review Nomenclature and Stoichiometry | Review Nomenclature and Stoichiometry |
| Reaction Products | Gas Laws |
| Thermochemistry | Kinetic |
| Atomic Structure | Equilibrium |
| Periodic Table | Acid-Base Equilibria |
| Chemical Bonding | Solubility Equilibria |
| Molecular Geometry and Hybridization | Thermodynamics (include Thermochemistry) |
| Intermolecular Forces | Electrochemistry |
| Solution Properties | Atomic Structure |
| Gas Laws | Periodic Table |
| Kinetic | Chemical Bonding |
| Equilibrium | Molecular Geometry and Hybridization |
| Acid-Base Equilibria | Intermolecular Forces |
| Solubility Equilibria | Solution Properties |
| Thermodynamics | Reaction Products |
| Electrochemistry | Review |
| Review | Exam – May — |
| Exam – May — |
Let me first start by stating that AP CHEMISTRY SHOULD BE A SECOND YEAR COURSE. This comes directly from the latest College Board publications. I am aware that there are many ‘interesting’ schedules that have been devised by schools to have AP Chemistry be the first course, but for the most part, Chemistry is such an abstract topic that most students need the time to fully grasp the concepts.
The topic can be broken into two categories – Memorization and Mathematical:
| Mathematical | Memorization |
|---|---|
| Review Nomenclature and Stoichiometry | Review Nomenclature and Stoichiometry |
| Gas Laws | Atomic Structure |
| Kinetic | Periodic Table |
| Equilibrium | Chemical Bonding |
| Acid-Base Equilibria | Molecular Geometry and Hybridization |
| Solubility Equilibria | Intermolecular Forces |
| Thermodynamics (include Thermochemistry) | Solution Properties |
| Electrochemistry | Reaction Products |
The traditional sequence may be easier for the new teacher and for many students to follow, but starting with the Mathematical topics allows for more review throughout the year and places the Memorization topics where they belong. The Memorization topics are basically a review of the first-year course.
One should also look at what happens at the end of the school year, just before the test. State testing, students visiting colleges, spring sports, and other courses take your students out of your class.
If you feel comfortable with ALL of the AP Chemistry topics, I recommend looking at the Alternative sequence.
When planning out the school year, I suggest that if you are following the Traditional sequence, be ready to start Kinetics after the Christmas (Winter) break. If you are following the Alternative sequence, be ready to start Atomic Structure.
Two topics are not found in either sequence – Nuclear and Organic Chemistry. These are great topics for the Christmas (Winter) Break and Spring Break.
Finally, I like to put Reaction Products at the end. With the new format of Question 4, this becomes a great review of the course.
One final thought. Leave time for lab. In recent years, the AP Chemistry test is requiring more lab knowledge and skill. Do not shortchange your students. Give them a rich lab experience. The two lab manuals that I use:
For this first unit, I recommend the following labs:
How to Utilize High School Chemistry for A.P. Achievement
If at all possible, each student should be given or be required to purchase a copy of the online video eBook. Within the first 2 weeks of class, Inorganic Nomenclature and Stoichiometry should be reviewed and tested. This is true if you use the Traditional or the Alternative sequence. This should be a time of review. It is important that your students have a solid background going into the upcoming AP Chemistry topics. The recommendations are the minimum that your students should do for each of these topics. I think you will find that your students will do more after they see the interactivity of the online homework.
Inorganic Nomenclature –
Chapter 1: Atoms, Molecules, and Ions
Begin with 1.17 Concept of Ion (Part 1)
Students should work thru section 1.47 Periodic Table (Molecular Compounds with Polyatomic ions and Hydrogen)
Stoichiometry –
Chapter 3: Mass Relations in Formulas and Chemical Reactions
Be sure students go thru 3.11 Percent Composition, 3.13 Empirical Formula, and 3.17 Molecular Formula
Chapter 4: Amounts, Stoichiometry, and Reactions in Aqueous Solutions
I recommend the students review the entire chapter.
As the instructor, during class, you should review Inorganic Nomenclature and Stoichiometry topics. Teacher-generated worksheets and an exam should be included in your overall lessons.
Good luck and enjoy the upcoming AP Chemistry year.
