 Scientific Method
Students will investigate the food preferences of garden slugs (Arion subfuscus) using simple equipment including margarine tubs, graph paper, scissors, and common plants, both wild and cultivated. The exercise is genuine scientific research in that: a) the student devises his/her own research question about slug feeding behavior, and b) the results are truly unknown to the student-experimenter (and possibly to the instructor) prior to the experiment. In carrying out the complete set of experiments described below, students learn that one way to achieve precision and accuracy is by designing experiments with many replicates.
