Use your lab notebook for pre-labs, laboratory reports and discussion questions, and post-labs. Never tear out the original pages from your notebook. If you made a mistake, cross it with a single line. If there is any unused space left on the page, cross it out with a single diagonal mark. Tear out and submit the copy pages for grading. Be nice to your TA
Write neatly and legibly. Always start the PRE-LAB on a new page. REPORT on a new page. POST-LAB on a new page. Number the Discussion Question answers. Don’t forget the insert page! 5 Turning in pre-labs and lab reports
Must be written on pages torn from your lab notebook. TA’s are not allowed to accept loose sheets of paper. Pre-labs are due during the first five minutes of lab Preon the day of the lab. Everything else (reports, discussion questions, postpostlabs, unknown summary sheets) are due during the first five minutes of lab one week after the experiment is performed. Late reports
Reports that are not turned in during the first five minutes of lab are late and will be penalized 10% per day. Turn in late reports to your TA, to me, to another 204 TA, or to the stockroom at any time. They will sign and date them and give them to your TA. 30% Quizzes

Let me know ASAP via e-mail. New labs estart on Wednesday morning. You can’t just get the data from someone, you must actually do the experiment to receive credit. Make-Up Labs
There is ONE make-up week at the end of the makesemester for doing missed labs. If you let me know of an absence far enough in advance, you might be able to make up the lab during the week and not fall behind. If you wait to tell me, all the spots will be gone. The Double Whammy
IF YOU ARE ABSENT AND MISS A LAB 1) You will get a 0 on that week’s quiz, and 2) you still have to take the quiz on the lab you missed when you return next time. 7 If you miss a week...
Check the lecture slides online to see if I said anything about what to expect on the quiz. Read the introduction to the experiment you missed. Do the post-lab problems for the experiment postyou missed. Scholastic Dishonesty
We take precautions to discourage people from cheating, and we make efforts to catch them. If you are caught cheating, we will submit all the evidence to the Dean’s office and you will get an F in the class. Don’t copy someone else’s work in order to turn something in on time. The late penalty is small on purpose. If you need help or feel overwhelmed, let me know and I will help. Today in Lab
