Part 1: Investigating the Responses of Pill Bugs to Moisture (8 points) In this part of the lab, you will explore the responses of pill bugs to moist and dry environments. You will begin by preparing a habitat for pill bugs and a choice chamber for an experiment. A choice chamber provides an organism with two distinct environmental conditions. You will place a moist paper towel on one side of the chamber and a dry paper towel on the other side. You will place the pill bugs in the middle and count the number that have moved to each side after a certain amount of time.
