Zero Mealworms Essay

Improved Essays
Conclusion
The hypothesis stating if certain stimuli (light, darkness, bran flakes, and apple slices) are placed in a chamber near a group of ten mealworms, then during 3 minutes a portion of the mealworms will have moved towards the stimuli, was refuted by the data showing how zero mealworms migrated into the stimulus chamber, during any point in any of the trials using each of the stimuli and the one trial without using a stimulus.
Discussion
The student designed experiment to investigate a mealworm’s response to a variable had the same results for each trial. During the first trial, a flashlight’s light was shone in the stimulus chamber and zero of the ten mealworms moved into the stimulus chamber in one minute, two minutes, or three minutes.

During the fourth trial two halves of an apple slice were placed in the stimulus chamber and zero of the ten mealworms moved into the stimulus chamber in one minute, two minutes, or three minutes. In the fifth and final trial, the stimulus chamber was emptied and had no stimuli inside. During the fifth trial, zero mealworms moved into the stimulus chamber in one minute, two minutes, or three minutes. The fifth trial was the control group in the experiment. The results of the experiment show mealworms are not always drawn to stimuli when the stimuli are just placed near the mealworms. Mealworms will not always go towards a stimulus nearby the mealworms. The results could also mean a three minute time period is not long enough for mealworms to react to a stimulus’ presence. Finally, the results of the experiment could mean the group of ten mealworms used were not as easily attracted to the stimuli used as other mealworms. Mealworms are shown to eat fruits, like the apple in the experiment, and cereal, like the bran flakes in the experiment. Mealworms are also attracted to darkness, like the darkness provided by

    The purpose of the lab was to observe the environmental impact on the behavior of pill bugs (Armadillidium vulgare) by using the steps of the scientific method. . We placed two pill bugs in an enclosed space and recorded the amount of time they spent in two categories of living spaces: hard rocks or soft sphagnum moss. Despite predicting that they would have a preference for a softer area, both pill bugs spent more of their time in the rocks than in the moss. This suggests that Armadillidium vulgare has a preference towards environments with hard surfaces over soft ones, possibly due to factors like light or surface area. However, certain experimental errors such as material density and poor handling may have skewed the accuracy of results.…

    We hypothesized that pill bugs would display a positive hydrotaxis and a negative chemotaxis, but our last experiment supports a reaction to chemotaxis. Since we placed them in a tray with all chemical-filled chambers, we weren’t able to tell if they drift towards diluted solutions because they contained more water. The products of the Chi Square Test told us whether the results of our experiments were significant or not. Our results in Part A and B were significant because the calculations proved the null hypothesis wrong and supported our hypothesis; the bugs displayed a positive hydrotaxis and a negative chemotaxis in these two situations. On the other hand, Part C can be invalidated because the bugs did respond when placed between 4 concentrated-chemical solutions.…

    Pillbug Lab Report

    The objective of the Isopods Lab was to figure out if the Pillbugs favored the wet environment or a dry environment. After reading the pre-lab report on Pillbugs, my hypothesis was that “If water is added to an Isopods environment, then the isopods will favor the wet environment.” By using two groups of Isopods, one group was put into a dry environment and the other had one drop of water into their dish. After ten minutes of observing the Isopods, the results showed that the Pill Bugs prefer the wet environment more. As time went on, the bugs in the wet environment survived longer than the Isopod in the dry environment.…

    In addition, the pillbugs were influenced by each other and were prone to crawling on top of each other. They made several attempts to get out of the tray and had to be prodded back in the container. The slight tendency of the pillbugs to migrate to the lighted side may be because they believed that the light indicated an escape route. Lastly, our group had used a concentrated light source for the lighted side, like a flashlight, in the original procedure. It seemed reasonable to balance artificial darkness (the construction paper) with artificial light.…

    Introduction: To fully understand the investigation, there are three main definitions to keep in mind. Thermal Niche is a development in which natural selection forms adaptation for an organism through temperature. Acclimation is the process for the organism to become accustomed to the climate change. Fitness is simply the survival of an organism, however, in the investigation, locomotion is more suited due to the focus on the affect temperature has on the organism’s performance. For this lab, the organism experimented on is a water flea, called Daphnia Magna.…

    Panda Express: Consider four bugs and their habitats. In temporary ponds we can find Green and Red Bugs, in permanent rivers we can find Orange and Blue bugs. The Green and Red bugs are food to fish and salamanders, but the Orange and Blue are unpalatable to both fish and salamanders. Salamander larvae are never found in the presence of fish and are quite palatable to fish. (a) Design an experiment that would reveal whether the larvae of each Bug “Species” can detect and respond to the presence of a predator (b) Why would the bugs choose either temporary ponds or permanent rivers to lay eggs based on the experience with…

    Within an article called “They Might Be Gross, But Intestinal Worms Can Actually Be Good For You” by Dr. William Parker of Duke University, a new perspective on the potential uses of intestinal worms, or helminths, as they are referred to, is given to readers. He argues that these creatures can actually be beneficial to the human health, along with the health of many other animals. Dr. Parker constructs support for his argument by using ethical appeal, logical appeal, and primary resources throughout the document. Parker continuously reinforces his argument by using ethical appeal in the article. Although there are many examples of its usage, one prominent use is when he stated, “(In) my lab, working with a Duke University colleague…” (Parker).…

    In the various chapters that we have gone through in this class, we have looked at various things in the environment that can alter how an animal acts, grows, and evolves. Like in Chapter 51 when we learned about animal growth and development. Or, Chapter 52 when we learned about “learned behaviors” like the Pavlov’s dog experiment and the “innate behaviors” of the female and male moths. The things that we learned in this class helped us to pick our experiment.…

    We, in the United States are meant eaters. Today’s news is often filled with the effects and causes of global warming, with the main focus being related to carbon gas (CO2) emissions, reducing oil-based and coal energy usage. By comparison, what is not well known or often reported, is the tremendous impact of raising farm animals, mostly cows and chicken, for food production, the strain on resources, carbon emission, and the corresponding toxic run-off, to name a few. By further investigating the results of these massive farm production undertakings, and how damaging their impact is to the planet as reported by John Vidal in an article published in “The Guardian”, the current way these animals are raised is more recently of interest by politicians, scientists, economists, and the UN alike. Our relationship with animals is severe and must be changed in order to help solve the human and ecological concerns, and solve the problem of the already 1 billion people who do not have enough to eat and the 3 billion more people to feed within 50 years (Vidal).…
