In this article, I'll take an in-depth look at the components of a successful AP Chemistry syllabus, including content coverage, lab work, and overall curriculum requirements. I'll also give an example of a full syllabus (based on a sample from the College Board) and provide some helpful tips for both students and teachers!

AP Chemistry is a wide-ranging course. The curriculum is divided into nine units that encompass long lists of smaller topics. I'll list the units along with the smaller themes within them.

There are also seven Scientific Practices that students are expected to master in the course, which I'll list after the Big Ideas. This is a part of the new inquiry-based model of AP science courses that encourages independent thinking. Finally, there are some overarching Curricular Requirements that every AP Chemistry class must fulfill, which I'll go over after the Scientific Practices. For the full course description with even more details, consult this link!

These six "scientific practices" represent skills that students are expected to learn in AP Chemistry. Many of these relate to correct implementation of the scientific method in a lab context. They're especially tied to the "Guided Inquiry" labs, where students work independently to plan and conduct experiments.

The curricular requirements are concrete statements of expectations for the AP Chemistry course. These include requirements for the types of materials teachers must use in class, the structural framework of the course, the opportunities students should receive, and the percentage of class time devoted to labs.

The following is a summary of a sample syllabus supplied by the College Board that goes through all the units that would be taught in a standard AP Chemistry course. It also provides the number of class periods allotted for each unit. This syllabus is based on the pre-2019 updates to the course, but College Board has stated class syllabi don't need to be updated as a result, so it still covers all up-to-date information. (The course materials below have been updated.) Check out the AP Chemistry course description for more information on how many class periods to spend on each of the new units.

Students learn how to measure mass and volume with varied pieces of equipment and focus on the accuracy of those pieces of equipment in their calculation and determination of significant figures. Students also determine the identity of an unknown organic liquid using density determination.

Students are given the materials to conduct various procedures. They construct a procedure for each of the eight changes to be observed, have their procedures approved by the instructor, and then carry out the procedures. The data collected is used to develop a set of criteria for determining whether a given change is chemical or physical.

Students perform a titration and then determine the concentration of an HCl solution by using a potentiometric titration curve and finding the equivalence point. Data is graphed in a graphing program.

Students examine a demonstration size model of DNA or an alpha helix, and use their fingers to identify which atoms / base pairs are particularly involved in hydrogen bonding within the molecule, causing the helical structure. Students then discuss how the increased UV light because of ozone depletion can cause chemical reactions and thus mutations and disruption of hydrogen bonding.

Students find the reduction potentials of a series of reactions using voltaic cells/multi-meters and build their own reduction potential table. Dilutions will be made, and the Nernst equation will also be tested.

A series of labs completed over a 4-week period. Students work at their own pace in pairs. The goal of this lab is to determine the empirical formula of a ferrioxalate crystal. It includes the following experiments:

These are some tips I came up with for AP Chemistry teachers based on my experiences as a student in the course. I struggled a lot with chemistry in high school (partially because my teacher wasn't very good), so here are a few things that I think would have helped me out at the time.

When I was in AP Chemistry, I had a hard time understanding how to solve complex multi-step problems. I often couldn't figure them out on my own, even when I had read examples in the textbook and seen my teacher go through similar examples. I'd advise teachers to do as many sample problems as possible in class.

It's important to give students background information, but walking through sample problems step-by-step is the most valuable practical instruction you can provide. You should also go through homework problem sets in class so that students can see exactly where they made mistakes and why. Encourage students to try redoing the problems with the new information they've learned to reinforce the correct methods.

Because AP Chemistry is such a challenging class, it's likely that many students will be interested in extra help outside of the designated class period. Although students should be encouraged to take the initiative in asking for help, I think it's also a good idea to set up a designated time when you'll be available after school.

Block out a couple of after-school hours one or two days a week, and encourage students to come to you with any questions or concerns they have about the class. You can also set aside times for review sessions before each exam that all students are encouraged to attend. These could even include chemistry-themed review games and competitions (if your students are true nerds they will love this).

To prepare effectively for the AP test, students need to get used to the format and timing. As you get closer to the exam, administer a few mock AP tests. Translate grades to where they would fall on the AP scale so that students have a better idea of where they're scoring and how much they need to study to reach their goals. This will help give them more motivation to study and force any stragglers to get serious about improving their scores.

Obviously, right? Well, not necessarily; zoning out during lectures is something that we're all guilty of doing because we're human beings. However, this is a class where you really, really need to pay attention to your teacher's explanations. It's hard to self-teach chemistry because you're not just memorizing facts, you're learning how to do different types of calculations and navigate a bunch of new terminologies. If you can only pay attention to one thing, make it the example problems that your teacher does in class. Take notes on the solution steps so you can refer to them in the future and refresh your memory.

If you don't understand something, get clarification as soon as possible. AP Chemistry isn't a class where you can let a few things fall by the wayside and still get by. The information builds on itself, so it's critical that you have a strong understanding of every concept. Gaps in knowledge will come back to bite you in the end! If you don't feel like you're getting enough of an explanation in class, don't be afraid to ask your teacher for extra help.

It will be tempting to say "oh, I don't actually need to do this problem set" or "eh, I'll read this chapter later." But if you do that too many times, before you know it you'll have no idea what's happening in class. This course moves very quickly from one complex concept to the next, so you can't afford to fall behind. As I mentioned, concepts build on one another. If you find yourself slipping and losing touch with what's going on in the course, ask your teacher for extra help as soon as possible to resolve the issue.

Review books can be very helpful for AP Chemistry because they're well-organized catalogs of all the different concepts you will learn in the course. There's so much packed into the curriculum that I'd recommend buying a book so you have something to ground yourself as you're looking back through the material.

You can use the review book for practice problems and AP review sessions throughout the year. Every couple of months, do a review of everything you've learned so far to keep the information at the front of your mind. Here's my list of the best review books for AP Chemistry to give you a lil head start.

To recap, the AP Chemistry syllabus revolves around six "Big Ideas," which are main themes that cover more specific concepts called "Enduring Understandings." Each AP Chemistry course is expected to give students the skills they need to understand these larger themes and connect them to a basic factual knowledge of the ins and outs of chemistry.

Additionally, an effective course syllabus provides assignments that enable students to master the seven "Scientific Practices" established by the course guidelines. It will also adhere to the rules established by the Curriculum Requirements.

AP Chemistry is a fast-paced class that covers complex concepts, but with a logically formatted syllabus and a concerted effort from both students and teachers, the course can be an enlightening introduction to a fundamental aspect of how the world works!
