Laboratory Organization

- There will only be two hours of regularly scheduled lab time per week, but your activities must extend beyond this class time in order to achieve a desirable outcome.

-The laboratory is designed to offer you the flexibility to choose the work you want most to do. That is, you may choose to pursue a set of ideas, reading about them, testing them out experimentally, and perhaps even extending them in ways that are of interest to you. You may wish to look through peer-reviewed sources (such as texts or the journals listed above), to find experiments that you would like to reproduce or apparatus to build.

In grading your notebooks, I am looking for clear evidence of thought and analysis - and the degree to which you pursue ideas.


Prepare For Each Lab:

Seek out appropriate reading materials!

(The very act of seeking is one of the most important habits to develop at this point in your education)

Your laboratory notebook should contain thorough sections covering each of the following areas, most of which require time outside of the regularly scheduled meetings (i.e., consider these tasks to be your homework for the laboratory portion of the course):


Grading notes:

Written work will be assessed according to whether or not it compellingly presentsclearapplication of physical and experimental principles.

Clearly conveying understanding is key!

Final course grades will heavily very weight your laboratory performance.
