The overall purpose of this investigation was to determine the effects of different types of environments on pill bug attractancy. Pill bugs were exposed to 2 different environments (sugar and water). The attractancy was observed and recorded in a raw data table. A research hypothesis was formulated that the sugar would work as the best attractant for pill bugs. Sugar had the greatest impact of the two environments used because it attracted 8/9 ants. Due to this the research hypothesis was supported. After further calculations if a person wanted to collect 64 pill bugs all he/she needs to do is spray this mixture of sugar around his house and everywhere in his backyard.
In our experiment, we examined the behavior of isopods by conducting the experiment based on our hypothesis: “If ten isopods are put into the test chamber, 5 in sand and 5 in soil, which environment will the pillbug prefer.” We hypothesized that the isopods would favor the soil more than the sand because pillbugs are typically found in soil and not in sand. Pillbugs are favored in soil because the natural role of a pillbug is to eat dead and decaying things but, in sand there are no nutrients available for pillbugs. Pill bugs are mostly found in moist environments, due to having gills, gills only function when they are wet so pill bugs will inhabit places in which air holds a lot of water
My group recorded higher heart rate compare to the class average when we used caffeine on the Daphnia as seen in Figure 2. Several errors could have accounted for this data. This including perhaps the Daphnia’s heart rate may have changed because of fear while being moved from the bowl to the microscope slide. Another possible error could have also been the amount of time that it took to change the solutions, which could have accounted for slight variations in heart rate. Temperature is yet a further error to account for as the microscope slide temperature was constantly changing to view the specimen, and change the dosage of caffeine or alcohol. The temperature of the solutions could also have played a factor in the Daphnia Heart rate as ideal conditions for Daphnia is 68 degrees Fahrenheit and the temperature of the solutions was not measured for.
In this experiment, Pill bugs were exposed to different environments within a closed space and observed to determine which environment they preferred. The four different environments tested consisted of flowers, dirt, grass, and an empty space. Ten pill bugs were placed within the shoe box and observed for a total of 15 minutes to determine what environment the bugs preferred. The independent variables were the different conditions in each section of the shoe box, while the dependent variable was the behavior the pill bugs displayed. Throughout the experiment, the control variable was the empty section of the shoe box. By the end of the experiment, it became clear that the pill bugs preferred the environment consisting of dirt over the other
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). This indicates that we are unable to show a statistical difference between Isopods preferring the syrup environment over the water environment.
The hands were washed. Goggles were placed on the eyes for extra protection. A petri dish containing nine pill bugs were obtained and set aside for later use. Two water bottles’ ends were cut and taped to each other creating a miniature tunnel for the pill bugs to crawl in. 50 mL of tap water was obtained in a small beaker and then was slowly moved into the lid of the bottle using a funnel. The sugar used in this experiment was created by mixing ten milliliters of starch,glucose, and regular countertop sugar. This was transferred into the joint water bottle tunnel using a funnel. Both ends of the tunnel were sealed shut and each measurements were taken every three minutes and final measurements were taken after 21 minutes. The results were
Imagine spending one year of your life living in a dumpster. Not just the average, everyday dumpster, but a customized dumpster suited to meet all of the essential needs for one to live in. Professor Jeff Wilson, also referred to as “Professor Dumpster,” is engaged in a one year project in which he will be sleeping in a dumpster every night. His future plans consist of making the dumpster even more appealing by adding a toilet, solar panels, a second floor, and several other amenities. Wilson says in the article, “‘We could end up with a house under $10,000 that could be placed anywhere in the world, fueled by sunlight and surface water, and people could have a pretty good life’” (James Hamblin ℙ4). In the article, “Living Simply in a dumpster,”
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.
Four randomly selected Daphnia magna, for each trial, were removed from the provided colony for the bioactive compounds to be tested, and were transferred with a plastic wide-mouth pipette with approximately 10 mL of pond water to protect and ensure survival of the Daphnia. In order to acclimatize the Daphnia to laboratory conditions, they were then placed onto a petri dish on the Daphnia cooling chamber. The cooling chamber was located on the stereomicroscope platform and brought down the heart rate of the Daphnia to a range that was countable by the observer, since Daphnia heart rate at room temperature is too rapid. On the cooling chamber there were two petri dishes: one for the Daphnia that were going to be tested, and one with the Daphnia being tested on, to ensure constant consistent temperatures for each trial. To maintain a temperature conducive to the heart

The overall worst team to ever play major league baseball would have to be the Cleveland Spiders. The Spiders started off the season winning only 8 out of 38 games. The team would then go on to win only 12 of their last 112 games. Their best pitcher of the year had a record of 4-22 on the season. Finally the spiders at the end of the season the Cleveland Spiders would finish 35 games out of 11th place, and 72 games out of first place. The worst major league baseball team record is held by the 2003 Detroit Tigers. Their record that year was 43-119 making them officially own the worst team record of all time. They own the fourth worst record of all time as well with the 1996 season when they went 53-109. They also own the fifth worst record off

The following experiment determines the effects of 50 ml tobacco extract on the heart rate of a crustaceans Daphnia Magna. Daphnia represents a small group of aquatic crustaceans, also known as “water fleas”, with clear exoskeletons, which makes studying their heart rate effortlessly. The heart rate can be observed using a microscope and counted under varying conditions. (Pritchard, J. B.) In this case, changing the type and concentration of natural plant substances reveals the effects of the plant defense mechanisms on the specimen of Daphnia Magna. Tobacco (Nicotiana tabacum) was the plant chosen for the experiment. Since, nicotine in tobacco is a stimulant, it is predicted that if Daphnia exposed to this substance would have an increased
