Lecture: You will receive copies of
my lecture notes and the guided inquiry workbook throughout the
course of the semester. These notes plus the textbook should
allow you to solve homework problems on your own. Because you
have already received the lecture notes, the lecture periods will usually be
group problem-solving sessions involving the POGIL
exercises from the Guided
Inquiry workbook. The critical thinking questions are
worked in class by your group. Your team work must work together on these
questions, so that every member of the team understands the team
answer. There will also be some group assignments which
don't come from the workbook.
Homework sets will be due each week on Friday at the end of the business day. All the exercises from each activity in the Guided Inquiry covered by Wednesday are due on Friday. That's the exercises interspersed throughout the chapter and at the end of each chapter -- but not the critical thinking questions. Don't confuse them. There will also be some additional computer exercises. Some homework sets will be group projects.
You should plan to work all the exercises and problems in Guided Inquiry. This text is a workbook, it is not a textbook, thus it is not a complete description of the course content. My lecture notes should help you, but you should also read the textbook by Atkins, or refer to chem libre text online, which has both exercises and problems at the end of each chapter. The exercises are relatively simple "plug and chug" calculations that are based directly on the text. (The problems at the end of the chapter are more difficult.) I encourage you to work with the members of your group on the homework problems. While you are studying the text, you should look at the exercises. You should read all the exercises at the end of each chapter in Atkins because they closely follow the presentation of the text, and therefore aid comprehension of the material. If you really want to learn from the Atkins book, try to work about half of the exercises at the end of the chapter. That will get you ready for my tests!
Tentative Schedule: Our goal this semester is to cover calculus, thermodynamics, thermochemistry, and chemical kinetics.

Evaluation: Twelve
tests will be given to you on Tuesdays through out the
semester. You are required to work on the quizzes alone, without
assistance from anyone but me. No assistance from other
students or other chemistry faculty or any online tutoring services.
These tests are scheduled for Sept 5, 12, 19, 26, Oct. 10, 17,
24, 31, Nov 7, 14, 28, and Dec 15. Note that there are no tests
scheduled on the week of Fall Break or the week of
Thanksgiving.
The two lowest test grades will be dropped from your average;
however, you may only drop tests that you actually take.
An unexcused absence from a test will result in a grade of
zero which cannot be dropped. If you
anticipate an excused absence, such as for sports, you
should arrange to take the exam before its date.
Each test will contain a bonus question; points from the bonus
question may be retained in your average even if the test
grade is dropped.
Tests can be picked up in science office on Tuesday mornings or received by email from me. Return the tests to office or to me before the start of Wednesday's class.
The Final exam is scheduled for 10:30 am Monday, Dec 11. The final exam is cumulative, covering the entire semester's material. You may bring with you one sheet of paper with handwritten notes on both sides.
Homework sets including computer
projects will be due at the end of each week. See the schedule of
topics for assigned problems. You should attempt all the
exercises at the end of each chapter because they closely
follow the presentation of the text, and therefore aid
comprehension of the material.
No homework may be submitted after 5 pm, Friday Dec 8, the last
day of class.
Two short reaction essays are also included
in your homework grade:
DUE Friday Oct 6.
Phillip Morrison Ring of Truth,
Episode 2 "Change". I also have this on DVD. Just the second half
of the episode on energy (at time 21:00 - it starts when you see
bicycles!)

Policy on the use of AI: AI tools can assist you in providing explanations and suggestions, but they should not be used for direct answers to graded assignments, quizzes, or examinations. Students should not submit AI-generated content as their own work; this will be viewed as a form of cheating or plagiarism. Be wary of AI-generated content – the information provided by AI can be inaccurate or incomplete. Students are encouraged to meet with the course instructor, PASS leader, or peer tutors for clarification on course content.
Lab reports are an important part of
this course. Lab reports for each lab experiment will be due
one week after the completion the experiment. You must turn in all
lab reports to receive a passing grade in the course. Unacceptable lab reports
will not be accepted! You
will be required to resubmit an unacceptable lab report.
You are required to work with your lab partner--the two of you
must read and evaluate lab reports before they are turned in to
me. An extensive list of online advice about lab report format, style, and content is
available on my web site. The lab report evaluation
form is also on my web site. During the semester there
will be lab report writing workshops during lecture--it is crucial
that you bring writing assignments to class on those days.
No resubmitted lab reports will be accepted after 5 pm, Tuesday
Dec 13, the day after the final exam.
The final grade will be determined as follows:
Comprehensive Final exam 20%
Homework and computer projects 15%
Tests
40%
(N.B. Because of the bonus points, it is possible
to earn up to 50% from the tests.)
Lab reports
25%

Laboratory: The laboratory course gives you the opportunity to measure physical and chemical constants. I will emphasize the importance of statistics in determining how precisely you have measured these constants. In fact, the early experiments are designed to teach you the use of statistics in evaluating experimental data.
Some form of eye protection, either plastic glasses or goggles, is required whenever you are in lab, except when you are working at the computer. You are also required to wear a face mask. There are no restrictions on the clothing you wear in lab.

The lab instructor will determine the groups and partners for all lab experiments.
You will find that I do not provide detailed lab handouts that tell you exactly how to do an experiment. In the lab you will find general information about the goal of the experiment, but it is up to you to decide how to do your experiment. And it is your experiment; you should have the pleasure of deciding how you want to do it. If I tell you how to do the experiment, you won't have as much fun because you'll be trying to get results that please me. All I care about is that you design an experiment that really measures what you want to measure, and that you estimate the precision of your measurement. Of course, I'll be there whenever you want to talk to me about your experiment. And in that regard, let me warn you that I am very opinionated and hold very definite ideas about the way things should be done in the lab. This is an inevitable consequence of spending twenty five years of my life doing chemical research. My job is to use my experience to help you avoid bad ideas and mistakes. Nevertheless, if you believe an idea you have is right, don't drop it just because I say it's wrong. Stick with it until you understand why it is wrong, or until you can prove to me that it is right.
You should keep some organized record of the work you do in lab, but I want you to decide how you want to do that; I am not going to grade your personal notebook. I will from time to time call you into my office and ask you to answer questions about your lab work; you can bring in your notebook and refer to it during these interviews. Therefore you need to record information in your notebook so that several weeks later you will be able to look at it and know what you did in the lab. By the way, you do not need to write down a detailed experimental procedure in the notebook; instead, refer to the lab textbook where you found the procedure. If you modify the procedure or apparatus, be sure to record the modifications in your notebook and lab report.

Groups will be rotated every two weeks on Monday. On the Monday before the new groups are assembled, there will be an in-class quiz with one problem based on homework. If every member of the group gets the problem right, one additional bonus point will be added to the previous week's quiz for every member of the group.
