The experiment was conducted in five trials. The pillbugs attraction to the substance was measured by the amount of time within one minute the pillbug was in the substance. Inside the crate the sand was placed on the left side followed by a cardboard divider and the cornstarch was placed on the right side followed by a divider, leaving a neutral spot in the middle where the pillbug was placed for one minute after each trial.…

We will be using the LoggerPro and LabPro in order to help us determine our data. The purpose of this experiment is to follow the changes of pH during the titration of an acid and a base in order to determine the of the weak acid, . is a constant for a given acid at a given temperature. In this experiment we determined the Ka using two different methods: 1) the measurement of the pH of a solution containing a known concentration of a weak acid, and 2) measurement of the pH at the half-neutralization point in the titration of a weak acid and a strong base.…
For future references what we could do to improve out methods of conducting this experiment is after each trial we should clean the choice tube to make sure there is no residue, which can cause miscalculations. Though the whole experiment we used different sizes of isopods. Maybe next time we can stick to one size throughout the whole experiment or we could do these trials by size. Preform the same trial a few times using different of pill bugs and see if the size of the pill bugs has anything to do with their…
In this lab we watched the particular conduct of physical isopods, ordinarily known as the pill…

The results from our experiment does support our hypothesis. When comparing and viewing the data of the amount of pullets that were recording, pill bugs preferred rotten fruit to rotten meat. The accuracy of our data was based upon the amount of times the treatment was repeated and the amount of Pill bugs that died. Pill bugs cannot live in a cold environment because they will freeze. Due to the irregular climate in the North country, that would be a factor that could not have been controlled and would be one of the variables that caused the pill bugs to die. If this experiment was replicated, a controlled climate and a longer testing period would help produce more stable results.…
This lab felt very “slow” because there was not a lot of action going on. The pill bugs would either walk around in circles or stay put. However, it was both fun and annoying when my group tried to put the pill bugs in the chamber and take them out. We had to put a lot of effort to get the pill bugs on to the paint brushes because they would scurry around and it would take a while to find them. Also, it was cool to see the pill bugs use their defense mechanism (it only happened once) by going into a hard circular shape when being prodded at by a paintbrush. This lab had a lot of experimental areas. The amount of water or basic or acidic solution to the paper may have affected results. For the first part of the lab, outside factors could have…
A. Create a solubility curve for NH4Cl by plotting g NH4Cl/100 mL H20 on the y-axis, and crystallization temperature on the x-axis. Make sure to label each axis. On the same graph as the solubility curve for NH4Cl, add the solubility curve for NaCl using the data provided in Data Table 3.…
Research a pill bug behavior. What type of environment do they prefer? Are the nocturnal or diurnal? What do they eat? Where would you go to find roly-polies?…
Our group made two separate mazes; one was the control while the other was the experimental. Each maze had two paths, the path on the right side and the path on the left side. The right side had only right turns while the left side had only left turns. In the experimental maze there was a longer left side to see if the pill bugs became discouraged the farther they went to their food so that they may turn around and go down the other path. There was incentive at the end of each path; the incentive that we used was dead leaves, which is their favorite thing to feast on. In the mazes we then took 10 pill bugs and put them into an open square that was carved into Styrofoam board. After the pill bugs were placed into the carved maze, they then waited three hours and evaluated to see where the pill bugs would end up.…
This might play a role on the movement of the crickets. The crickets might have become impaired when the chamber is tilted at an angle. This impairment might influence their movement and sense of direction. This can be easily solved by improving the chamber being used in this experiment. Last possible error is that during the in-between of the two trails, the chamber did not expose the odor long enough, before the second trial begin. This might make the odor flows into the other side of the chamber, causing both sides of the chamber to be covered with the scent of cinnamon. This can be solved by waiting for at least 5 minute between trials. This finding might have a major influence in the field of ecology. By understanding the organism’s behavior, scientists can create a possible habitat that will fit their needs. For example, polar bear is becoming extinct because they are losing their home, due to global warming. If ecologists understand how the polar bear interact in their environment, they can create an artificial habitat that will suit their needs. This finding might also benefit the field of…
The pill bugs used in this experiment were all acquired from the same source, a habitat consisting of soil, paper towels for shelter and water. The experiment will require the use of two, five chamber arenas as well as two, two chamber arenas. It will also require a pill bug sample of at least twenty specimens, and a supply of filter paper to use as the moist and dry bedding for the pill bugs in the arenas.…
