LECTURES

DISCUSSION/LABORATORY SECTIONS

---

Please note that currently, all sections are full and have wait lists. There is no preferential enrollment; no PTEs will be issued for any sections. Concurrent Enrollment students are NOT guaranteed enrollment in this course.

Please note that if you are dropped for any reason (usually a late fee payment), you will NOT be able to immediately re-enroll in a section that has a closed or wait-listed status. You will have to get on an open wait list; you will not be given preferrential enrollment. This includes students dropped due to registrar/computer error or other administrative problem.

You must attend the section in which you enroll because of (a) limited seating in the classroom and (b) the in-class quizzes that may take place in the discussion sections. Please check your Official Study List to ensure that you are attending the correct section, since you will not get quiz credit if you are attending the wrong discussion section.

There will be NO makeup and NO alternate-scheduled (i.e., "early") exams, unless otherwise required by OSD and California Education Code Section 92640(a). Please note that Exam #2, taking place during final exams week, is non-cumulative and is scheduled for only two hours, not three.

Examinations are multiple-choice and short-essay. Please bring your photo identification, either student ID, driver's license, or passport. The exams are closed book unless otherwise noted beforehand.

LABORATORIES

The 1-unit lab section is an optional add-on to the 4-unit lecture/discussion.

If you entered UCLA before Fall 2002, you will get credit for one Physical Science GE with lab/demo component without needing to enroll in the lab section. If you want to get 5 units of credit for this course, you can enroll in the lab section.

If you entered UCLA during and after Fall 2002, you will get 4 units of Foundations of Science GE credit if you take just the lecture/discussion component. If you need to fulfill the requirement for one Physical Science GE with lab component (5 units), you need to be enrolled in both the 4-unit lecture/discussion and the 1-unit lab section.

In any case, if you are going to take the 1-unit lab course, you need to be enrolled in it during the same quarter you are enrolled in the lecture/discussion. The lab section takes place both in and out of our departmental computer lab, so there should be no scheduling conflicts. For labs that require use of our computer facilities, you will sign up for 2-hour blocks of time on a workstation during regular business hours.

QUIZZES

Instead of long homework assignments, we will have three “take-home” quizzes. These are fill-in-the-blank questions related to lecture material and the textbook (if you have one), and probably will take you 30-60 minutes to complete. These will be given out at the end of a lecture (and also posted on the web site) and is due at the beginning of the next lecture. Late quizzes are not accepted for any reason. This means if you walk in late, your quiz will not be accepted. If you have a regularly occurring situation where there is a good chance you will be late to class when a quiz is due (for example, you commute and this is your first class of the day), you should probably email or fax the quiz to me sometime beforehand. Email or faxes must be received before class begins (3:30 pm on the due date). You can be excused from one of these quizzes if you miss it or are late due to some unforeseen circumstance; this means that discretionary travel does not excuse you from a take-home quiz, since you can plan to email your quiz.

There will also be several in-class quizzes. These will be given either at the beginning or end of lectures, or at the beginning or end of discussion sections. They are open-book, open-notes, and you can work with other people in the room. They are just like the take-home quizzes, but should only require 10 minutes to complete. Only five of the seven in-lecture quizzes are formally scheduled (Thursdays of odd-numbered weeks); the other two may be given at any time without prior warning. It is therefore imperative that you attend as many or all lectures and discussions as possible, since you will not be able to make up an in-lecture quiz for any reason, including emergencies and illness, and you cannot get credit for in-discussions quizzes taken in any discussion section other than the one in which you are enrolled, unless you got prior authorization from Dr. Lew . You are only required to complete 5 of the 7 in-lecture quizzes and all 4 of the in-discussion quizzes (see the lecture schedule for the specific weeks) in order to get full credit for the quizzes. You may do more of the quizzes if you like--if you do more than five in-lecture quizzes, one lowest score will be dropped and the points from the rest of the quizzes will be added together; if the total is above 100 points, the excess will be considered extra credit. Because you are not required to do every quiz, there will be no excused in-lecture quizzes.

Section hops, which is when you attend a section in which you are not enrolled in order to take a discussion quiz, are only allowed once per quarter, and these need to be arranged with Dr. Lew before the section hop takes place. Otherwise, the hop will be unauthorized and your quiz will not count for credit. This only needs to be done for the weeks that an in-discussion quiz takes place. Any other week, you are free to go to any discussion section you please.

If you have some outside obligation that conflicts with more than one of the scheduled quizzes, you are highly discouraged from taking the course at this time, because there cannot and will not be any quizzes given outside of class and at times other than when they are given to the class as a whole.

All quizzes (take-home and in-class) are to be written by the person submitting the quiz. This means you cannot have someone else write up your quizzes on your behalf (you must be present to take an in-class quiz), and quizzes cannot be copied/pasted into multiple e-mails. These kinds of behaviors may be referred to the Dean of Students for prosecution.

READING

Suggested reading assignments from the text will be announced in lecture and tabulated on the web site. Readings are intended to provide additional reference for lecture material. You are not required to learn and/or memorize everything in the reading material, since exams are based on the lectures. It would be helpful if you read through the assignments before the relevant lecture, in order to become somewhat familiar with terms and definitions.
