Lab Policies
  • This is lab section M06, which meets Thursdays from 3.30p-5.30p in Walden Hall, room 232. There are 14 labs during the semester, and they are worth 20% of your final grade.
  • Attendance is mandatory. If you have to miss lab one week and let me know ahead of time, or if you are sick and have a doctor's note, you may be able to make up the lab with another lab section. You are still required to turn in the previous week's lab on time. If you miss a lab and you do not have an excuse, you will receive a zero for that day's lab.
  • Read the intro section of the lab before showing up to do the lab. Skim the rest of the lab. It will make your life (and mine) much easier.
  • Calculators are cool! Cell phones are cool, too, but they can't do scientific notation or cube roots, so bring a calculator.
  • Each team must turn in one copy of the team work, and each individual must turn in his/her own take home section. Any instances of plagiarism will earn a zero for all parties involved. See the class syllabus if you are unsure what constitutes plagiarism.
    • Make sure you put your name on the team work copy.
    • Please staple your lab and make sure the pages are in order.
  • Labs are due one week from when they are assigned unless otherwise noted.
    • Late labs will not be accepted unless you speak to me ahead of time (or during lab) and explain why it's late. In those cases, you will be allowed to turn in your lab one day late with no penalty. Repeat offenders will not be tolerated. You can turn in late labs directly to me (office 121 in the Astronomy Building) or to my mailbox (next to the Main Office in the Astronomy Building).

Suggestions
  • Show your work.   I'm a big fan of partial credit, but it's hard to give you points if the only thing you write down is a wrong answer.
  • Remember your units.   2 hours is very different from 2 seconds, and 26.2 miles is very different from 26.2 cm.
  • If you're confused, ask!   Talk to me, your team members, or other teams if you want to check your answer, if you're totally lost, or if you're somewhere in between.

 
If you have any questions about lab, class, astronomy in the news, or anything else, don't hesitate to ask me!

You can come see me during office hours, talk to me after class, send me an email, give me a call, randomly stop by my office, or (of course) talk to me during lab.
