Pill Bugs Lab Report

Introduction In nature most organisms cannot change the nature of their environment therefore they must position themselves in an environment with favorable conditions to themselves and their offspring. This behavior is called habitat selection. Many organisms will exhibit a tactic response to these environmental factors. This tactic response can be positive or in favor of a certain environment and negative or against a certain environment.

The purpose of this research was to observe the general behavior characteristics of Pill Bugs (Armadillium vulgare) and design experiments to determine whether Pill Bugs are adapted to sense certain environmental changes and how they respond to those changes or what their tactic response is. The behaviors

The Animal Behavior tray was used to create two different habitats for the Pill Bugs to choose from. The watch was used to time the experiment in order to take down data after every minute for ten minutes. The five Pill Bugs were the organisms used to create the habitat selection experiment. The hand lens was used to observe the Pill Bugs closely during the experiment. The two filter papers were used to help keep the behavior tray clean. The pipette was used to put the water into the behavior tray to create the wet environment in the second part of the lab. The water was used to create the wet environment. The procedure for the control part of the experiment starts by taking the Animal Behavior Tray and placing the filter paper in both sides of it. Next take the five Pill Bugs and place them into the behavior tray. Start the timer on the watch and observe the amount of Pill Bugs on each side of the behavior tray and how they are acting. Record this information at the end of every minute for ten minutes, in Table 1. For the second part of the experiment, using the pipette and water, place the water on the filter paper on one side of the behavior tray. Allow the filter paper to absorb the water therefore creating the wet environment. Next, place the Pill Bugs in the behavior tray and observe the amount of

At the end of minute one there were four Pill Bugs on Side A and 1 pill bug on Side B and the Pill Bugs were observed to be bunched together. At the end of minute two there were five Pill Bugs on Side A and zero Pill Bugs on Side B. At the end of minute three there were four Pill Bugs on Side A and one pill bug on Side B. At the end of minute four there were three Pill Bugs on Side A and two Pill Bugs on Side B and the Pill Bugs were observed to be active. At the end of minute fivc there was one Pill Bugs on Side A and four Pill Bugs on Side B and the Pill Bugs were observed to be very active. At the end of minute six there was one Pill bug on Side A and four Pill Bugs on Side B. At the end of minute seven there were three Pill Bugs on Side A and two Pill Bugs on Side B. At the end of minute eight there were four Pill Bugs on Side A and one Pill Bugs on Side B. At the end of minute nine there were three Pill Bugs on Side A and two Pill Bugs on Side B and the Pill Bugs were observed to be active. Finally at the end of minute ten there were five Pill Bugs on Side A and zero Pill Bugs on Side B. The wet and dry habitat data was collected second in Table 2. At the end of minute one there were zero billbugs in Side A or the wet side and five Pill Bugs in Side B or the dry side. At the end of minute two there were four Pill Bugs in Side A and one Pill Bugs in Side B. At the end of minute three there were four Pill Bugs in Side A
