2) Abstract: Can’t exceed 250 words

a. background information

b. procedure description – not specific

c. Results – must include at least one statistic from each section (sowbug, (and brine shrimp if used for the lab)  (chi square value, degrees of freedom) significant or not significant.

d. conclusion – relates to results (includes taxis and kinesis)


3) Introduction/Background: Must include background on behavior/habitat/characteristics, must include parenthetical citations (ex.... (Smith, 2005). (key concepts and words; isopod, crustacean, terrestrial, marine, behavioral characteristics, habitats...)

8 (4)

4) Results: (note number each data table example Figure 1: Sowbug Moisture and Light Preference)

8 (4)

(note number each graph example Figure 1: Sowbug Moisture and Light Preference)

b. Two graphs – If x-y scatter used, must show trend line and equation, y = mx +b, titles descriptive, axes labeled with units (one sowbug; one brine shrimp... can be either group or summary class) Equations need to be labeled also (click on equation and then enter label in front of equation in text box).


c. Trend paragraph – must include info that describes what is in data tables and graphs. Include chi square and/or slopes


d. Chi square calculations - should be last page as an appendix, handwritten includes whether or not results are significant and degrees of freedom Chi Square Tutorial  Chi Square Chart     (ex. is 3.14< or = to 3.84 (df=1, p=0.05) yes, no significant difference between observed and expected values, the null hypothesis Ho is supported) 


5) Conclusion/Discussion: Explanation of results – must relate background info and results; includes parenthetical citations, statistics (with degrees of freedom), includes significance of results, support or rejection of either hypothesis or null hypothesis, discussion of taxis and kinesis.  (how to write a Power Conclusion)


6) References – use primary sources (Wikipedia is a secondary source and can only be used as a 3rd or higher reference).  Wikipedia references found at the bottom of the topic pages are usually a good place to find reliable source materials.
