Required Materials

Our textbook for the quarter is General, Organic, and Biological Chemistry by H. Stephen Stoker (7th Edition).


There are several formats available from the bookstore & other retails (hardcover, loose-leaf, eBook, rental, used, etc.) Any format is fine - pick whichever format will be most convenient and affordable for you.

Course Components & Grading

Grades will be assigned at the end of the quarter using these course components:

Category % Description Breakdown
8% 10 Weekly Recap Quizzes 1% each, drop 2
45% 4 Midterm Exams 15% each, drop 1
20% Final Exam
Disc. Sections
8% 10 Weekly Meetings/Wksts 1% each, drop 2
2.5% 5 Pre-Lab Assignments 0.5% each
2.5% 5 In-Lab Participation 0.5% each
10% 5 Lab Reports 2% each
Sapling HW
4% 12 Assignments 0.4% each, drop 2

Historically, the average student in CHEM 220 has earned a grade between a 2.6-2.9. In general, students obtaining more than 95% of the course points earn a 4.0.

Synchronous Practice Sessions (Lecture)

Synchronous course lecture times (M-Th, 8:30-9:20am) will be used to discuss the material, allow for Q&A with Dr. R, give an overview of upcoming assignments, and work through practice problems together. These Zoom sessions are not required and attendance will not be monitored. They will be recorded to allow for asynchronous viewing.

Online Homework

Sapling Learning. Practice is an important part of learning. This quarter, we will be using Macmillan's Sapling Learning platform for our homework practice problems. Assignments will be available for approximately 2 weeks prior to their deadlines. Due dates are noted in Canvas and in Sapling. To make sure your account is appropriately linked to the course gradebook, you should register through the link on the Canvas site (registration is $26/quarter when purchased directly through Sapling).

Scoring & Late Assignments. To receive full credit, you must submit the correct answer on the first attempt prior to the deadline shown in Sapling. If your initial submission is incorrect, you may resubmit answers for partial credit. Should unexpected circumstances arise that you are unable to complete your assignment by the due date, you will be able to submit responses in Sapling for an additional week for half of earned credit.

Discussion Sections

Every Friday, you will meet with your discussion section synchronously on Zoom. During this time, the teaching assistant will review some of the week's topics, provide time for questions, and guide the group through some practice problems. We encourage you to sign into the Zoom call with your video enabled when possible and on a device where you can access Google G-Suite functionalities to facilitate group work. There are 10 meetings of the discussion sections throughout the quarter, and participation credit will be given each week for your contributions to your breakout groups on worksheet questions. Two discussion sections participation scores will be dropped to allow for absences. No make-up assignments will be offered.

Weekly Recap Quizzes

The quiz assignments will be available for 24 hours from 8:30am on Thursday mornings until 8:30am on Friday mornings. You should expect 5 short questions (multiple choice, select all that apply, true-false, etc.). Once you open your quiz, you'll need to work alone to complete it within 20 minutes.


CHEM 220 includes five laboratory exercises during the course. You only need to attend the 3-hour lab section during the experiment weeks (see the lab schedule document). Each experiment has one pre-lab assignment, an "in-lab" participation component, and one lab report assignment. See the lab policies for more information.

Midterm Assessments & Final Exam

We will have 4 midterm assessments and a cumulative final exam this quarter. The lowest midterm score will be dropped from your course grade to minimize the impact of illness, absence, or technical difficulty on your grade. The assessments will be posted as PDFs and available for download at 8:30am on exam days. You will then be able to work through the exam (either filling in your answer on a printed copy, on a tablet/device, or on blank paper numbered according to the exam file). At the end of the exam time, you will create a PDF of your completed assessment and upload it to Gradescope. A practice upload and more specific instructions will be provided prior to the first exam.

Regrade policy. Exams are graded using specific rubrics within the Gradescope platform. If you would like a grader to revisit your exam, you may place that request through Gradescope within 1 week of the midterm scores being published to you.

Access & Accommodations

Your experience in this class is important to us. It is the policy and practice of the University of Washington to create inclusive and accessible learning environments consistent with federal and state law. If you have already established accommodations with Disability Resources for Students (DRS), please communicate your approved accommodations to Dr. Robinson as soon as possible, so we can meet your needs and support your success in this course.

If you have not yet established services through DRS, but have a temporary health condition or permanent disability that requires accommodations, you are welcome to contact DRS at 206-543-8924 or DRS offers resources and coordinates reasonable accommodations for students with disabilities or temporary health conditions (mental health, attention-related, learning, vision, hearing, physical, or health impacts).

Washington state law requires that UW develop a policy for accommodation of student absences or significant hardship due to reasons of faith or conscience, or for organized religious activities. The UW's policy, including more information about how to request an accommodation, is available at Religious Accommodation Policy. Accommodations must be requested within the first two weeks of this course using the Religious Accommodations Request form.
