Pill Bug Lab Report
The pill bug (commonly referred as rollypollys) is a small, segmented land creature that can roll into a tiny ball for protection. Which is classified as a crustacean under the order of Isopoda (Isopoda). The organism is generally characterized by a pair of antennae, seven pairs of legs, and a segmented body (Isopoda - Slaters). Whenever it is disturbed it usually curls into a ball until there no longer a threat. The typical sowbugs or pillbugs live in moist environments outdoors. This is due to the presence of gills, isopods generally live in moist, wet areas and avoid lighted areas. In addition, their diet consist of leaf litter, fish flakes and other vegetation (Burnett). In addition, these organisms do not bite, sting, or transmit diseases, infest food, clothing or wood (Sowbugs and Pillbugs).
METHODS AND MATERIALS In preparing the lab, artificial nurseries are needed for the arriving isopods. After receiving the isopods, the amount were divided and placed into the nurseries overnight to adjust to the new environment. The isopods were carefully monitored and fed daily with raw potatoes, apples, or fish flakes. In performing the experiment, six isopods were collected either with a spoon or scoopula and placed in a petri dish prior for the experiment. After collection, the …show more content…
In which, both the chi-squared test and the observation of the pillbugs appears to prefer the moist chamber than the dry chamber. The possible errors associated with this experiment include, the isopods climbing over each other. At times it would block the connecting chambers preventing the flow between the chambers. In addition, the rocks used in this experiment were slightly moist and may have affected the experiment. Some further investigation include increasing the test size, testing whether isopods prefer light or dark and the pH the isopods

    Why Is Pillbug Attracted To Cornstarch

    A pillbug also known as a roly-poly is a small land creature that is often found in many areas around the world. They prefer moist areas often living in soil, under rocks, and dead logs. The pillbug which is an isopod begins its life as a tiny egg and as it grows it sheds its old exoskeleton 4 to 5 times. A pillbug consists of three basic body parts, the head, thorax, and the abdomen. Pillbugs eat decaying plants and animals as well as some living plants. The purpose of this experiment was to learn how to demonstrate the scientific method and to learn if pillbugs are attracted to cornstarch. In this experiment I hypothesize that if a pillbug is exposed to cornstarch and sand then the pillbug will spend more time near the…

    Pill Bug Science Project

    For this project I had observed the coolest bug balls on earth, the roly- poly. They are commonly known as the roly-poly, also pill bug, and wood lice. Its scientific name is Armadilidum vulgare. It is actually not an insect, it is an isopod ( a type of arthropod). It’s genus is Armadilidum, it’s Phylum is Arthopoda, and Subphylum is Crustacea. I have observed that the exoskeleton is a blue-gray, it is an invertebrate, it’s mouth, antennae and eyes are located on it’s head, and it rolls into a perfect sphere as defense when being disturbed or threatened. It has 2 pairs of antennae (one barely visible), it has 2 eyes, it has 7 pairs of jointed legs, and it’s about 3/8 inches long.…

    Pill Bug Synthesis

    Some conclusions that we got were that pill bugs are not well adapted to areas that might be colder or pill bugs won’t exist in that type of weather. Pill Bugs live under rocks or even beneath the rocks. As it is seen on figure 1 the pill bugs had more movement on the 25 C than in the other temperatures. Therefore, pill bugs 25 C is their normal habitat temperature because it has a perfect weather for them to be able to survive. One probable error that the group had was when one of the pill bugs die during the 0 C temperature because it was too cold for them. At the end of the result it was conclusive that the pill bugs had few movements during colder temperatures like 0 C and 35…

    Sowbugs Research Paper

    Contrary to their name, sowbugs (Porcellio laevis) are tiny crustaceans that live in moist environments around the world. These creatures, about 12.5 mm in length, are extremely unique in their physiology, habitat, diet, and behavior. Sowbugs are harmless to humans, but incredibly important to ecosystems. They are found easily in nature, and are quite hardy (Franklin, Julie A.) Though they use gill-like structures, called pseudo tracheae, to breathe, sowbugs cannot breathe underwater but are highly dependent on moisture for survival. Sowbugs can only live in habitats with high humidity and low exposure to light (Buddies, Science). Sowbugs prefer sheltered, humid areas as the sun’s bright light dries them out (Potter, Michael F).…

    Carolina Natural Selection For AP Biology

    Natural Selection is the environments’ favoring of a particular trait in a population. Organisms use many different methods to adapt to their environments. In this experiment one must use brine shrimp and salt water solutions to represent organisms and their environments. Some organisms like the brine shrimp adapt to changes in their environments. Brine shrimp eggs produce cysts when their environmental conditions aren’t being cooperative. Brine shrimp eggs grow hard and brown when their environment does not have enough oxygen to support them. This also happens when there is too much salt content in their environment. When the eggs become hard and brown, they can be kept for long periods of time in a dry, oxygen- free environment. When the cyst is returned to its normal environment, it continues on with its development and eventually hatches. Brine shrimp are the perfect organisms to do experiments on because they only require a short time for development. The person conducting the experiment must use 5 beakers, each with different amounts of salt in them. The point of the experiment is to see how the brine shrimp eggs respond in each dish of salt concentrate. Once the salt and water have been combined, one must place approximately twenty brine shrimp on a microscope slide. After twenty four hours, some of the brine shrimp eggs should have hatched while some have partially hatched or not hatched yet. This must be done at the twenty four hour mark and the forty eight hour mark. The data should be written down on the chart given in the experiment papers. The hatching viability must be found by adding the number of hatched eggs at twenty four hours and the hatched eggs at forty eight hours and dividing it by the initial amount of eggs placed in the petri dish.…

    Cinnamon In Crickets Essay

    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…

    Pill Bugs Research Paper

    All animals try to adapt to the environment to survive. The real question is why do living organisms react to environmental factors? For example, a chameleon will change colors to hide from predators. Bears hibernate in the winter to conserve energy because of the food shortages. Likewise, pill bugs avoid light and try to make homes in dark, damp environments and eat decaying plant and animal matter. The reason pill bugs prefer dark and damp environments is because they behave negatively to phototaxis, which is the response to light, and have a partially positive behavior towards hydrotaxis, which is the response to moisture. The reason I say partial behavior is because they do not prefer to live in an all-dry habitat, but they also do not find large bodies of water an ideal habitat as well. In this specific scenario, the object of the…

    Osmosis Lab Report

    Diffusion and Osmosis are two concepts that go hand in hand with each other. Diffusion is simply described as the movement of a substance from a region of high concentration to a region of low concentration. In another words, the substance will move down its concentration gradient which is “the region along which the density of a chemical substance increases or decreases” (Campbell Biology pg. 132). If you understand the concept of diffusion then osmosis is a very simple process. It can be defined as the diffusion of water across a permeable membrane. Osmosis can be cellular or artificial, so even though we are creating artificial cells in this lab, it is still considered to be osmosis. During osmosis, a solvent is trying to get through a selectively permeable membrane to make the concentration of that solvent the same on both sides of the membrane. The rate of osmosis depends on the type of environment the cell is in. There are three different environments that a cell can find itself in, a hypertonic environment, a hypotonic environment, or an isotonic environment. The environment a cell is in will determine its tonicity which is “the ability of a surrounding solution to cause a cell to gain or lose…

    4 M Egg Osmosis

    As discussed in the intro, the purpose of this lab is to observe principles of homeostasis and osmosis in action. The results of this experiment showed that eggs placed in a 4 M sucrose solution lost mass over time and had the greatest percent difference in mass compared to the eggs in other solutions, with the 4 M egg having an average of -25.13% difference in mass. The 0.0 M solution egg only had a 12.28 average percent difference in mass, the 0.5 M egg with 10.39%, and the 1 M egg with the least percent difference in mass, 6.40%. The 0.0, 0.5, and 1 eggs all ended up gaining mass over time whereas the 4 M egg was the only one to drastically lose mass. This occurred because of the levels of concentration of solute in the different solutions. Since the 4 M solution had the highest concentration of solute, compared to the other three solutions tested, and a higher concentration of solute than that of the solution inside the egg, it was a hypertonic solution.…
