Pillbug Lab Report Hypothesis

864 Words4 Pages

Description of Experiment: Hypothesis Actual Hypothesis: If the majority of the pillbugs are on one side of the choice chamber, regardless of the conditions (wet or dry) of that area, then the rest of the bugs will move to that area. Null Hypothesis: The majority of the pillbugs being on one side of the choice chamber does NOT affect where the rest reside to. Alternative Hypothesis: If the majority of the pillbugs are on one side of the choice chamber, then the minority will control/convince the majority to come over to that side. Materials 10 Isopods (Pillbugs) Isopod choice chamber Paper towels Stop watch Graph paper Methodology We will put 9 out of the 10 bugs on the dry side of the choice chamber by hand, leaving one in the middle of the choice chamber to make a decision. If the bug walks over to the dry side, as opposed to the wet side, where the bugs are known to be attracted to those conditions, then it will give us the possible theory that pillbugs are communal animals, swayed more by majority rather than their familiar habitat. We will repeat the experiment multiple times to see how many of the bugs can be swayed by the majority, starting with 1, and ending the experiment with 4. Independent Variable: Bugs placed in dry habitat (starting with 9, ending with 6) Dependent Variable: Bugs that move over to the majority's habitat (starting …show more content…

Our hypothesis was proven because throughout our experiment the pill bugs continuously chose the side with more bugs on that side no matter the condition (wet/dry). I was unable to find any viable sources that stated that they have conducted an experiment with the same or similar hypothesis to what we had in our experiment and there are also no viable sources about pill bugs that said that they were in fact social. This makes our hypothesis unique in that as far as the internet goes, nobody has performed an experiment like

    Students started off with a population of ten Skittlefish (skittles) on an orange reef (construction paper). The skittles had varying colors, and the adaptive trait being examined was the ability to blend in with the reef so the predators would not find them. The hypothesis that was thought up was that individuals’ survival was based on their location and coloring. The first year began with two of each color, and 5 Skittlefish were eaten that “year”. The ones eaten were two green, two purple, and one red.

    In this experiment, the question that was asked was, are elephants afraid of mice? The hypothesis is if a mouse is placed near an elephant, then the elephant will be frightened. The experimenters traveled to an African safari to perform the experiment with their test subjects (an African elephant and a white mouse). They hid the mouse in elephant dung and rolled over the dung whenever elephants passed by. At first there was speculation that the elephants might have been startled by the moving dung.

When police and medical examiners got to each crime scene, they learned that all of the hostages were given drugs and had overdosed on them. Some of the pills, in powder form, were found near the victims. One of the victims was stable enough to tell the investigators that the power on the floor were the drugs they were forced to take. The medical examiner found out each hostage was given either unknown A or unknown B.

  • Isopods Vs Pillbugs

    1003 Words  | 5 Pages

    In this experiment, we are testing whether or not the Isopods' have more of a preference for an environment with syrup or with water. The alternative hypothesis we devised is that if the Isopods are placed in between a syrup and a water chamber, then they will go towards the syrup chamber. This is believed because we believe the Isopods may have an attraction to the sweet scent and taste of the syrup. My group and I observed 10 pillbugs behavior over the span of 5 minutes, recording the number of pill bugs found in each chamber every 30 seconds. We fail to reject the null hypothesis because the chi squared value is 3.6 which is less than 3.84 (critical value at .05).
