Lectures are Monday and Wednesday at 1:00 PM in CNS-204. Laboratory is on Tuesdays 9:25 AM to 12:05 PM, also in CNS-204.
There will be a problem-solving and tutoring session on Fridays at 1:00 in CNS-204. Details will be announced in class. Your laboratory work is central to the course. Attendance in lab is mandatory and will be taken in the first minute of lab. Your attendance over the semester will count as one lab. Complete lab reports and homework are due at the beginning of the next lab (i.e. you have a week to work on the lab), otherwise they are late. Staple your lab separately from your homework when you hand them in - they will be graded separately. 10% will be deducted for each school day a lab or homework is late, for a maximum of five days, after which you will receive a zero. Note that "late" begins one minute after the start of the lab when assignments are due. Although you may discuss the course material and labs with others, all written material handed in for grading (e.g. lab reports, calculations, answers to questions, and homework) must be your own work. If you discuss material with someone else, then you should go off and do the solution completely on your own. This is a good way to test your understanding. Also remember that I am frequently available and welcome questions at my door most anytime I’m in the office. | ||||||||||||||||
| Notes: |
This is a hands-on course. You will get the most out of it if you think about and question what you are doing while you are doing it in lab.
I’ll be in lab to answer any questions you have. I do not grade you on your questions. Those that seem the simplest are as important as any others, so let ’em fly.
You have plenty of time in the lab to work on more than just getting the data. As you are working, do a preliminary analysis and ask yourself if the data make sense. If they don’t, you can make the measurements again. This is easy to do while you are still in the lab, but hard from your dorm room. The laboratory is a great time to get a lot of your work done and to ask me questions on sticky parts. All units should be expressed. We will generally use engineering units in the course. This is scientific notation with the extra requirement that the exponents are powers of 3. You will see the value of this as we go along. All calculations from theory should be done with 3 significant figures. All those from data require you to consider the accuracy of the measurements you have made. In most (but not all!) cases in this lab you will be making measurements to at least 2 significant figures. Guidelines for making good graphs will be handed out later. What I like: • Questions during lab - even ones like “Does this look right?”
• Questions on Monday about work due Tuesday and after you have worked on it over the weekend.
• Questions after you have looked at the solutions and still don’t understand.
What I don’t like: • Questions by people who are late to class about material I have just covered.
• Homework that shows no effort.
