Pill Bug Experiment

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

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

4. Describe what is measured as an indicator of sucrase activity and why this is an indicator of sucrase activity.

Carbohydrates, lipids, proteins, and nucleic acids are organic molecules found in every living organism. These macromolecules are large carbon based structures. The macromolecules are assembled by joining several smaller units, called monomers, together through a chemical reaction called dehydration synthesis. The resulting polymer can be disassembled through the complementary process called hydrolysis.Carbohydrates are made of carbon, hydrogen and oxygen atoms in a 1:2:1 ratio. This means that for every carbon atom present in the carbohydrate there are two hydrogen

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.

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

This lab investigates the question how does changing the amount of sugar affect the growth rate of rock candy?

In this lab I will be exploring how temperature impacts the rate of osmosis by placing pieces of potato of equal size in solutions of different temperatures and observing the change in mass of potato after a given period of time. The change in mass will indicate the rate of osmosis.

In this lab, our main focus was to find how sugar concentration affect yeast respiration rates. This was to simulate the process of cellular respiration. Cellular respiration is the process that cells use to transfer energy from the organic molecules in food to ATP (Adenosine Tri-Phosphate). Glucose, CO2, and yeast (used as a catalyst in this experiment) are a few of the many vital components that contribute to cellular respiration. Sugar/ glucose is an important carbohydrate that can be made during photosynthesis from water and carbon dioxide, using energy from sunlight. Carbon dioxide is given off as a waste product when energy is released by the breaking down of glucose. This can be used by plant cells in the process of photosynthesis to form new carbohydrates. Yeast is a single-celled fungus that can break down sugars (glucose) to help produce carbon dioxide.

My PESTEL analysis for this piece of writing is based on the famous international lingerie

There is a well-known story that had been going around New England and is about a bug. This bug resided in the wood of an old table, which stood in the kitchen of a farmer for sixty years. The bug traveled with the table, first to Connecticut and then to Massachusetts. The bug started off as an egg that was placed inside of the tree and remained in the wood of it for years. The bug hatched inside of the tree, hidden beneath the tree’s many layers. It continued to live and thrive inside of the tree, and it remained unapparent to the outside world. How could you not believe, or have your faith in resurrection and immortality strengthened from hearing of this bug? The tree provides shelter for the bug, giving it life, which presumably seems impossible

The table seemed slightly imbalanced, and since the flies demonstrate a negative geotaxis, meaning that they resist gravity, the flies may have been influenced to choose one side over another simply by gravitational means. Another error that may have occurred could be the source of light. Though the lab group aimed to maintain an equal amount of light for all sides of the bottles, a vaguely estimated spot was determined and the choice chamber placed there. Since fruit flies also demonstrate a positive phototaxis, this also affects them. The last error that may have occurred due to tape. Though caution was emphasized, and extreme carefulness had been placed in the taping process, some tape may have gotten inside the bottle, and fruit flies may have been stuck to it, which had skewed data.

The experiment shall use several concentrations of sucrose solution and a substance known as Methylene blue. A piece of potato/ carrot shall be placed in a boiling tube and the solution shall be poured into it. This tube shall have Methylene blue added into it. After incubation some of this solution shall be taken out with a pipette and inserted into a separate boiling tube containing the same sucrose solution however this solution shall be known as the pre-incubated solution. The drop shall be watched so as to see if the density of the water and concentration of sucrose has increased or not, displaying the water
