AP Bio gives pillbugs a choice

Science teacher Erica Everett’s E block AP Biology class is investigating kinesis behavior in pillbugs. Students designed experiments to see whether pillbugs preferred moist or dry environments, using petri dishes that are connected with a passageway “choice chambers”.
Students decided that the ‘ultimate’ cause for this behavior is natural selection favoring those pillbugs that move towards moist environments. They are land dwelling crustaceans, and depend on their gills to be moist in order to function properly.
Ap Bio combines their lunch with class on day 6 so that they can have longer times for lab, and these become “Lunch Labs.”
