Note: the very last day to hand in a lab report is Thursday, May 1 (reading day).
Lab handouts will be provided for you.
The goal is to develop good laboratory technique, which yields accurate and precise results quickly.
Grading: 100% lab results (7 experiments); grade primarily based on accuracy & precision, as well as significant figure mistakes and calculation errors. An example of the grading scale is given in the laboratory handouts. The late penalty is 10% per weekday.
Three "good" trials are required for each result. If a result is rejected and a calculation error cannot be found, the experiment must be repeated. Once all seven experiments are completed, you may go back and repeat an earlier lab to better your grade.
