Purpose: The purpose of this lab is to observe the behavior of the Armadillium vulgare (roly- poly bug), as well as hypothesize whether it will be attracted to, repelled by, or unresponsive to certain substances.
1. Observing the pillbug: examine the pillbug’s shell and body, shell shape, color, texture, number of legs, number of antennae, motion, speed, and sex after close examination.
2. Formulate hypotheses: choose substances (powders and liquids) and suggest whether the pillbug will be attracted to, repelled by, or unresponsive to each substance.
3. Perform an experiment: using a control, test the pillbug’s reaction to the substances
