An example of this type of observation might be to record the arthropod occurrences in a clear cut on sunny days in a 10 meter diameter area. Perhaps you wish to document changes in arthropod activities as average temperature changes through the term. So you mark out a 10 meter circle in a clear cut. You go out on sunny Saturdays to this 10 meter circle and make detailed field notes of the arthropods you see and when you see them. You make drawings, with dimensions noted, of some of your observations.
Expectations concerning a term paper probably seem more obvious.
Some less obvious possible combinations might include a small component of field observation along with typical library research, combined in a term paper format. Most of the support for your conclusions would come from your library research, but it might be tempered by some of your own field observations. Since this is a biology class, please use citations consistent with those found in scientific journals. If you do a web page , please take extra care in the accuracy of your content, and the quality of your writing, grammar, and spelling. Be sure that you have several people proofread your potential web site before you link it and consider it complete.
