Ok, so I just found this great set of powerpoints slides done by a HS teacher.

You might find them as a good additional aid to your studying…

For our next phase

There is a typo in the syllabus. Labs will be accepted up to 72 hours after they are due, not 36. Sorry.

For the many of you who are having issues with unit coverversion stuff, I HIGHLY recommend you print out this 2 page worksheet and plow through it. It was written partly by me and should help, but you actually have to do it. Let me know if it helps or if it can be improved.
Unit Conversion (aka DImensional Analysis) Worksheet

The Monday quiz is really the closest thing to a test that I have. Even though the questions will be slightly changed, their essense is the same so the questions being posted on Thursday represent a psuedo take-home test.

Because of that, I will not be providing you with the answers to the questions nor helping you do the problems except to answer questions like ‘I do not understand what the question is asking’. Clarification questions are prefectly fine. “Is this the rigth answer” kind of questions are not.

If you want to know if you did it right, I strongly suggest you search for answers from the crew of people you consult with for in-class problems, each other.
