The following experiments are required. Since we have limited equipment, you will sign up fo a date to begin each experiment. The report for an experiment will be due the week following your scheduled completion of the experiment. Make sure you coordinate your use of any equipment with the other students who may need it. The total amount of time needed for the experiments is 8.5 weeks so you will also need to do more than one experiment at the same time (multitasking) to finish before October 23. All reports for assigned experiments are due no later than October 23.
