Extra Credit Homework! This is worth 10 points added to your lab grade, which comes out to a 1% boost to your overall course grade. If you're borderline or think you will be, make sure you do this and turn it in on time. Borderline cases that blew off the opportunity for extra credit won't receive a lot of sympathy when grades are assigned.

Here is a sample preliminary writeup. It includes
1) your name, section number, TA's name and the date
2) the title and objective of the experiment
3) spaces for any data collected, including blank copies of
all the data tables in the lab manual
4) a place for sample calculations.
And here is a sample report. It shows the data tables filled in, the sample calculations, the final calculations. You will also include answers to the discussion questions and printouts of the graphs we make in lab as part of your report.
Remember that all your work for lab should be written directly in your notebook, so although these examples were done on computer, you should handwrite the preliminary writeup and the final report in your notebook.
Here is a point breakdown that tells you how many points each part of the lab reports are worth. You can use this to keep track of your grade over the course of the semester. (This table is also available for download on the Grading page.)
What do the quizzes look like? Here's a sample quiz from last semester.
EXPERIMENT 1: An explanation of standard deviation as experimental error, courtesy of the chemistry department at the University of the West Indies in Jamaica.
MORE ON EXPERIMENT 1: One way to determine the error in the slope of a line is called the box method. We didn't bother with this in Experiment 1, but it's not hard, and Excel can even calculate it automagically for you. Our Jamaican friends have a page on that, too; just click the link and take a free etrip to Jamaica!
EVEN MORE STILL ON EXPERIMENT 1: Our procedures in Experiment 1 didn't really allow us to compare the accuracy of the three types of glassware, but it can be done, and it's worth knowing how they compare. For your own edification, here's a brief, onepage comparison of accuracies of the three types of glassware we used in Experiment 1.
