Lectures
The course meets on Tuesday and Thursday at 1pm  2:20pm in Crow 204.
Inperson attendence is not required but is strongly encouraged, since the material presented in lectures defines the course (there is no required textbook) and we use regular inclass exercises to reinforce learning.
See the Grading section for information on inclass quizzes.

Grading
Grades will be determined by a combination of homework, a midterm exam, inclass quizzes, and the final exam.
The final grade will be a weighted average of
 homework (25%)
 midterm exam (35%)
 final exam + quizzes (40%)
 Contribution from Quizzes:
 If you do better on the final exam than on the quizzes, we
ignore the quizzes, and use your final exam grade as 40% of your course grade.
If you do better on the quizzes than on the final exam,
we use 30% final exam plus 10% quizzes.
So the quizzes can't lower your grade, but they can help compensate for a
weak performance in the final exam.
Your two lowest quiz grades will be dropped, to allow for occasional
absences.
 PASS/FAIL:
 A grade of C+ or above counts as a "Pass".


Homework
 Purpose and Format:
 Tests your understanding of material we have already covered
 Contains multiple choice questions, along with regular questions or a short report
 Must be submitted via Canvas by the due date and time.
 Late homework will only be accepted by prior arrangement with
the assistant or the professor
 Collaboration:
Students are encouraged to form study groups and
discuss the course material with each other, but each student must
independently formulate his or her own homework solutions.
Please make sure you understand the university's
policy on academic integrity, especially the section on
"Copying Or Collaborating On Assignments Without Permission".
 Partial Credit:
When answering a question (other than multiple choice),
you will usually only get partial credit
if you just write down an answer, with no justification. To get full
credit you need to give reasons why your answer is correct.
 Showing Units:
When giving numerical answers, always show the units (eg
100 kg, 500 Calories, etc).
Inclass Quizzes
 We will have one inclass quiz every week, on average.
 The quiz will end 10 minutes after the start of class, but students can (by prior arrangement with the professor) arrive early and start the quiz when they arrive, so there is no time limit.
 Answers will be collected via iClicker.
 Each students's two lowest quiz grades will be ignored in calculating
final grades.
Exams
 The midterm exam will be in class on Thurs Oct 10th, 2024
The final exam will be at 1pm on Tuesday Dec 17th, 2024
 The exams will have no time limit. Students can stay as long as they like,
or (by prior arrangement with the professor) arrive early. Students who
arrive early will have to stay until the official start time.
 Each exam will resemble a homework as much as possible: it will include
some multiple choice questions and some longanswer questions.
Rules for Quizzes and Exams
These rules apply to quizzes and the midterm and final exams.
 Each student may bring and consult a single lettersize
"crib sheet" of facts and formulas. Both sides of the sheet
may be used, but everything on the sheet must be written or generated
by the student themselves. It should not contain copies
of documents generated by other people.

For the exam you are expected to know (or write on the crib sheet)
important general numbers that you might need to answer a realworld question, such as the rough cost of domestic electrical power, the power in sunlight, the output of a large power station, etc. You do not need to record detailed numbers from tables in the book or lecture slides, such as the energy density of gasoline or the atomic number of Carbon. Those will be provided if needed.
 Each student is expected to bring a calculator to the exam.
Calculators that can graph or do algebra are permitted. Calculators
(e.g. cell phones) that can connect to the internet or other external
sources of information are not permitted.
 When answering a question (other than multiple choice),
you will usually only get partial credit
if you just write down an answer, with no justification. To get full
credit you need to give reasons why your answer is correct.
