ABSTRACT Pill bugs live in an outside environment where they are able to get the necessary amount of energy from organic matter. This environment is where water and organic matter is plentiful. In there natural habitat, pill bugs are found in dark, damp places. Living in moist places is important for pill bugs so they can take in enough water, and if water is not available, they group together to prevent water loss. Pill bugs most often live in dark places because they have a negative photo taxis. Darker places also tend to be cooler and damper. Each experiment connected to how the pill bugs would behave in a certain environment. We were able to test these experiments in a laboratory way to see if the natural environments were also true.…show more content…
Kinesis occurs when the animal moves in a random motion in response to the stimulus. Throughout this lab, we put the pillbugs through four different tests. These experiments are to test to see if these animals will prefer a certain habitat rather than another and how they show this is through either kinesis movement or taxis movement. MATERIALS AND METHODS In all labs, a lab book and a pen or pencil are essential to record the number of pillbugs. The times come up fast so you have to make sure you are watching the clock or stop watch. Obviously, do not poke the pillbugs or try and force them into a certain chamber aggressively, this will aggravate them and cause unreliable results. When you are trying to get your pillbugs, use a paintbrush to sweep them onto your brush and then carefully place them into the choice chamber dish that is provided for you. Make sure to get 10 pillbugs so you can have five in each chamber. If they look dead, they are most likely just curled up. During the various tests, make sure to take notes on the appearance, the types of movements (kinesis or taxis) and the interactions between the animals. The first experiment is to find out if the pillbugs prefer dark or light environments. The choice chambers have a little passageway between the chambers. Make sure to gently place five pillbugs on each side and then block off that doorway with a cardboard barrier of some sorts. Pick one of the chambers and then cover that chamber with
