Pillbug Lab Report

In our hypothesis we stated that if we have music on one side, and no music on the other, the pill bugs will all attract to the side with no music. A Styrofoam divider was placed into the shoe box, with 5 pillbugs on each side. One side was playing music, and the other side wasn't. This experiment was timed for 10 minutes, after every minute the pill bugs were counted on the side with music, and on the side without. In our experiment the independent variable was the music, our dependent variable was the pillbugs, and our controlled variable was the amount of pillbugs used. The side with the music averaged

A two-part study was recently done to show what natural habitat a Pill bug, Armadillidium vulgare, naturally prefers: wet or dry environments along with a light or dark environment. It was hypothesized that a Pill bug would prefer and wet and dark environment based on its natural habitat of soil. For the wet and dry experiment, a coffee filter and soil were placed in each chamber of a double petri dish with one being dampened before being placed in. For the light and dry experiment a light was hung above one chamber of another double-chambered petri dish while the other chamber was covered with aluminum foil, after placing soil in both chambers. An equal number of Pill bugs was placed in each chamber and a study was taken for

The hypothesis that was tested was pill bugs are use to the cooler temperature of the room and natural soil would travel a greater distance once they were in a hotter environment. The hypothesis is rejected on the basis that the p-value of .760 is greater than .05. Furthermore, figure 3 supports this rejection, since the averages are very close to each other and their error bars completely overlap. This rejection means that once the pill bugs where in the hotter environment there was not difference in their behavior compared to the cooler room temperature environment; they did not travel longer distances. However looking at bugs D, F G and H in figure 2, there is a difference in distance traveled that appears to be greater than

The purpose of our experiment is to test animal behavior and reactions to a change in environment. Our guiding question is, “Why do living organisms respond to environmental factors?” This is basically a question that is asking why living things will react a certain way to environmental changes. The task to answer this question is to experiment with changing environmental factors with pill bugs.

Background- This lab is being done to demonstrate the effects of stimulants on the circulatory system of blackworms. In this lab, the stimulant we have chosen to use is Nicotine. A stimulant is an agent that causes increased activity, especially in the nervous or cardiovascular systems. In this lab, we will put blackworms into the Nicotine to look at the differences in pulse rates when compared to a control. The proper name for blackworms is Lumbriculus Variegatus, they are freshwater worms most commonly found in North America and Europe. The blood in blackworms circulates from the dorsal blood vessel toward the head through a series of

The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

A Chi-square test was used for hypothesis testing. This is used to determine that the observed number of wins of the resident from the trials is different from what would be observed by chance. The null hypothesis was observed wins will be equal to that expected by chance. On the other hand, the alternative hypothesis was observed wins will not be equal to that expected by chance. The class’ hypothesis was proven correct that resident male crickets have a greater motivation to defend

The Mexican Jumping Bean is indigenous to Mexico and has a peculiar life cycle. The process begins when a moth (Cydia deshaisiana) lays its egg inside a plant (Sebastiania pavoniana) then the egg incorporates itself with the seed of the flower. When the larvae hatches it eats its way to the inside of the flower. It lives their until the spring rains come which separates the seed into 3 pieces (Each of those pieces harden and turn into a brownish color.) and one of those pieces is where the larvae is.

Each team started by taking an infrared thermometer and recording 5 temperatures of two microhabitats relatively close to one another that may have different temperatures, such as wet sand and a plastic cover adjacent to one another. It was then hypothesized that the fake organism, the marshmallow peep, would experience more thermal stress and greater/faster thermal rise on the plastic than in the opposing microhabitat the wet sand. Two packages of peeps each containing five fake organisms were opened up and tiny I-buttons were embedded on the inside of each peep to measure body temperature over time while in the respective microhabitat. After twenty minutes of having five peeps with five I-buttons planted in each microhabitat, the I-buttons were removed and the teams returned to the lab to extract the data from the I-buttons. Using the I-button software, data from each I-button was downloaded and then exported to excel where statistical analysis and graph work could be completed to see how the results lined up with the stated hypothesis. Inside of the software, it was simple to “start view”, click on the “wizard” tab, click “next”, and press “finish” to start up the mission, and then plug the I-button into the socket, select the software, click on “mission status” and press the quick graph button to see the graph and export the data. The data addresses the hypothesis question because it will allow the team to view the temperature over time and thermal rise in the two opposing microhabitats and this will inform the group as to whether the hypothesis should be supported or refuted. The statistical analysis used on the data included an ANOVA (analysis of variance) consisting of SS, df, MS, F, p-level, and F crit as well as mean and

But surprisingly they went to the coffee side more. The second and third test the mealworms went more of where I originally thought. I figured that all three of the test would be more like the last test was like. Mealworms can be a pest in a house. They can get into your flour, corn meal, or any other type of house grains (Arizona, 1997).

For this experiment we were given superworms to experiment on. It was up to use students to decide what experiment we were going to perform on the worms. My group and I decided that we were going to observe how the size of the worms would affect how they reacted towards natural objects such as: sticks, rocks, leaves, mulch, and a pinecone vs an artificial object such as a straw. While doing this experiment, we observed the independent variable, dependent variable, the constants, and the controls of this experiment. I hypothesized that the larger worms were going to be able to move over the objects and that the smaller worms would have a more difficult time moving over the objects.

When 10 pill bugs are put in a bi chamber one side with strawberries and one side without will the pill bugs be affected by them. They were

In this experiment, there are no significant ethical considerations as we had not used any living organisms. There were no extreme safety concerns, however there are still precautions that needed to be taken. Cobalt chloride is very toxic and is irritating to the skin so when handling the cobalt chloride solution, wear lab coats and safety goggles and have all hair tied up. Handle the solution with care to try and prevent the solution from coming into contact with skin. If it does spill onto skin, wash it off with water and soap. Do not touch your eyes when handling this substance to prevent it from entering your eyes.

Experimenting on the animals the results that they get are not always accurate. Not all

The null hypothesis of this experiment was that there would be no significant difference in preference by crickets between environment with cinnamon and without cinnamon. The result showed that as the time increase the crickets’ movement actual become more stable. There is an equal net force of movement from one side of the chamber to another. To test the significance of these findings, a Chi Square analysis was performed. According to the Chi Square statistic, the null hypothesis should be accepted because the Chi square value (4.50) is less than the critical value (11.07), thus making the cinnamon having very little effect on the crickets’ movement. Even the control group yields similar result, that there is no difference of the sides that
