Woodlouse Water Preference

Wet and Dry Environments To find whether Pill bugs gravitate toward a wet or a dry experiment, two coffee filters were cut to the size of the petri dish and placed inside, however one was dampened before being placed on the bottom. Dirt was then added on top to promote a more realistic environment and five Pill bugs were placed in each side before starting to prevent bias on an environment. A log was taken every thirty (30) seconds for ten (10) minutes on how many bugs were in each chamber and a graph was then made to show the changes of the bugs' positions over time. Again, if a Pill bug was in the transgression tunnel he was determined to be in a dish by the direction he was moving or the way it's head was facing.

In this gummy bear lab, the goal was to see the movement of water in cells depending on the concentration of solutes in the environment. The control group was the type of water used. The research question for this experiment was, how does concentration of solute in the environment affect water movement in cells? The hypothesis thought of for this question was that the salt water would enlarge the gummy bear the most. The distilled water would not enlarge the gummy bear as much as the salt water.

The isopods used for this experiment range in color from gray to brown and were about 8.5 to 18 mm in length. Each Isopod’s head had one pair of antennae and one pair of antennules, both used to detect sensory stimuli from the environment around the pillbug. Their bodies were made of a hard thorax with seven segments and an abdomen. Each pillbug had seven pairs of legs, one for each segment of its thorax. Pill bugs breathe through gill-like structures and must live in moist places.

-Arthropods use pheromones, this includes sowbugs and cockroaches. Chemical signals are picked up by antennae.

The main reason of choosing the stimulus for the lab group was to conduct an experiment to see in which colored light that pill bugs prefer more out of red and blue. If pill bugs went to red more than blue lights, in which means they like bright light more. The pill bug move slowing in red side of the chamber then moves to blues side of chamber, where it return back to red side of the chamber where it stay immobile .The pill bug adapted to red and blue light which show more significant their locomotive movement.

1The isopods will gather in the wetter environment instead of the dry environment. 2The isopods will have an affinity to a more basic region than an acidic region. 3The isopods will tend to gather in the environment with a greater amount of light, than an environment with no light. 4The isopods will take a liking to a warmer temperature environment than a cooler temperature environment.By looking at the data you can see that there is a preference among isopods to favor an environment that is cold, wet, basic, and dark. We included the observed data as well as the expected data. Our expected data show what the information would look like if it came from a null universe. To come from a null universe means that the data will have no difference,

Pillbugs and sowbugs are terrestrial isopods that belong to the order Isopoda and the arthropod class crustacean. According to the Current Topics in Microbiology and Immunology, the terrestrial isopods have evolved from the marine forms. However despite the fact that they seek moist environments they must also avoid an overly moist environment (Journal of Insect Science, 2008). The two different species resemble one another phenotypically. However, pillbugs are a dark gray and the sow bugs are a light gray with posterior projections. Pillbugs also curl into a ball when they feel endangered and the sow bugs do not. The pill bugs used in this experiment were female. Isopods primarily live in dark, damp habitats in order to prevent dehydration (Isopod Behavior Lab). The purpose of this experiment was to determine the type of environment isopods prefer. First we tested to see if the isopods preferred a dry or moist environment and then we tested to see if they preferred the potting soil or the leaf litter environment. For the observation of isopods in response to moisture experiment it was said that each of the two different species would prefer a different environment. For part two, Observation of Isopods in response to other variables, it was hypothesized that the Isopods would prefer the potting soil or the leaf litter environment.

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.

Each section we added ( ml) of liquids. The null hypothesis that the growth of plants will be at its optimal value with tap water having a neutral Ph. The alternative hypothesis that there will be no change on the growth of plants in different liquids. Introduction:

All living things respond to stimuli, including animals. In our experiment, we tested how roly-polies, or pill bugs, respond to two types of material: wet sand and wet dirt. Pill bugs are isopods, a group of 10,000 species living on land and in fresh water and ocean. They are under the phylum Arthropoda, class Crustacea, containing both crabs and shrimp. Pill bugs generally live in dark, moist environments with the decaying matter they eat.

“Waterlily” by Ella Cara Deloria begins with a woman named Bluebird giving birth to a child named Waterlily while away from the caravan. The story shifts to a memory from Bluebird’s childhood about how she lost her family to a possibly raid or attack by another tribe while gathering supplies. However, the only other living relative happens to be her grandmother. Later, Bluebird and her grandmother set off to find a neighboring tribe. Eventually, Bluebird meets a young man named Star Elk. Bluebird goes on to marry Waterlily’s father, Star Elk, who happens to be a terrible husband. However, Bluebird remarries Rainbow. The story finally shifts to focus solely on Waterlily. During her childhood, Waterlily and her family are invited to attend a Sun Dance. Also, she witness her cousin, Leaping Fawn, participating in a Virgin’s fire and learning the proper way to accept a marriage. Eventually, Waterlily is brought by Sacred Horse because she felt that she must fulfill these obligations due to her family. However, Waterlily has a hard time adjusting to her new life and the new role she has to play. Waterlily begins to miss her family and people but she finds a sense of comfort with Red Leaf’s parents. She is finally able to relax with people she can relate to. Back at camp, an outbreak of smallpox spreads throughout the tiyospaye due to buffalo blankets. Sadly, Sacred Horse catches the sickness and requests to die alone. Leaving a pregnant Waterlily without a husband. Waterlily and

During the lab of testing whether the color of a pen will affect the movement of a termite, it was discovered that termites are more likely to follow a black and purple pen, rather than a red, blue, or green pen. It was hypothesized that if a blue, red, black , purple, and green pen were used, then the termite would follow the black pen because of it’s comparable scent of that of pheromones. This was proven correct based on the data and graph. Also the purple pen had pheromones in it’s scent like the black pen, concluding that only black and purple pens contain pheromones. But, the purple pen resulted in a much slower travel time from the termite. Approximately 15.83 average seconds were trimmed off from the black and purple pen.

The behavior change that I chose was to drink more water every day. Furthermore, my more specific goal was to drink eight glasses per day. My long-term goal by the end of the behavior change project was to drink eight glasses a day, because that is the recommended amount that a healthy human being should drink. I set short-term goals to help make my behavior change easier to accomplish. My short-term goals were to drink two glasses of water per day by the end of week one, four glasses of water per day by the end of week two, and six glasses of water per day by the end of week three. When going through this behavior change project, I personally discovered that there are not only many benefits from this behavior change, but also many barriers.

Two circles were drawn directly across from each other on plain white paper. One was drawn with a black Sharpie marker, and the other was drawn with a black ballpoint pen. Three separate termites were dropped directly in the middle of the two circles, and their reactions were recorded for sixty seconds. This was repeated once for each termite.
