LECTURE WORKSHEETS Lecture Worksheets The purpose of the lecture worksheets is to make you aware of some of the basics that will be covered in Chem 110 lecture, in the hopes that you will get more out of lecture through this kind of preparation. It can also serve as a guide in reading the text, increasing your understanding of what you read. Lecture Worksheets are to be turned in at the beginning of the Chem 110 lectures. There will be a box in the front of the lecture hall marked: Chem 108 Lecture Worksheets . Early lecture worksheets will be accepted. Anything past the indicated due date (the date of the Chem 110 lecture to which it corresponds) will not receive credit! In general, Lecture Worksheets will be graded based on effort rather than results, i.e., if the assignment is done on time and with reasonable care, full credit will be given, even if there are some mistakes in the work. PLEASE: do not disturb the lecture to turn in your Lecture Worksheet. Be considerate of your peers and Chem 110 lecturer. Turn in the worksheets prior to the beginning of lecture or immediately afterward. THANK YOU!
