Bullfrog Dissection Background The American bullfrog, Lithobates catesbeianus, is an amphibian about the size of a teacup.(National Geographic, “American Bullfrog”). This dissection explored the anatomy of a bullfrog that had been pithed. Pithing is a technique used to prevent the frog from experiencing any cruel or unusual pain during the dissection. A pithed frog has had its nervous tissue in its brain severed thus allowing it to maintain normal bodily function during the dissection without…

The VCE mathematics topic that I have chosen is Probability, in Mathematical Methods Unit 1 Area Study 4: Probability and Statistics (VCAA, 2015). The first section presents a literature review of student learning probability. It also addresses the common pitfalls that may impede their learning. The second section outlines a unit plan for teaching probability based on the new VCE study design. Sample activities worksheets and assessment tasks are included in the appendices. Literature Review:…

Analysis: Initially after I received my results from the GMI survey I was surprised by their outcome. Being a Global Studies major, I thought that my overall averages would have been significantly higher than they were. However, after reading through the aspects of each individual section, and a close inspection of myself in regards to the requirements to those sections I began to understand the reasoning behind my scores. When I first started assessing my GMI results, I expected my scores to…

Describe the research question for this experiment. The research question for this experiment is which vaccine is more effective for preventing getting the flu: the shot or nasal spray. What were the null and alternative hypotheses? Null Hypothesis: The shot is more effective than the nasal spray. Alternative Hypothesis: The shot is not as effective as the nasal spray. Were the results of this test statistically significant? .08>.05 Which means the results are not significant. The hypothesis…

Linear mixed models for repeated measurements were conducted with the variable of occupation after injury as a covariate. The results of the linear mixed models showed statistically significant differences between the experimental and the control groups in terms of changes in self-care knowledge (β = 1.696, P = 0.004), selfefficacy (β = 5.547, P < 0.001), and self-care behaviors (β = 11.694, P < 0.001) after the 8 week program. Selfcare knowledge, self-efficacy, and self-care behaviors…

The percent error of the calculated percent water and accepted value is 3.36%. The mean of the class data for percent water was 50.8% and the standard deviation was 0.0300. Compared to the class results, my percent water was lower, but very close to the mean. The standard deviation has a low number; hence the data are not as spread out from the mean. One source of error that contributed to this percent error was that the hydrate, MgSO_4, may have been heated too long. This is a random error…

Numerical Memory Study Consent Form You are being asked to take part in a research study of how much numerical information you can retain. What the study is about: The purpose of this study is to learn how well you can remember a sequence of numbers using the Auditory and Visual tests. What we will ask you to do: If you agree to be in this study, we will provide you with a link to the test via the internet using a classroom number. You will click on the link and begin the test will take…

The question investigated in this experiment was how does the sow bug’s preference of habitat affect the concentration and distribution of the organisms. The purpose of this investigation was to decipher what habitats these organisms prefer to live in and how it would affect their population density. This was tested by a simple experimental design with four petri dishes that each represented a different environment. The control treatment was the dish with just dirt while the other habitats…

The Benefits and Drawbacks to an Interactive Learning Environment One of the greatest challenges in the pursuit of teaching is providing an engaging environment in which students can learn and retain the knowledge gained. In the Stansbury and Munro (2013) experiment, as well as the research conducted by Ciarocco, Lewandowski, and Van Volkom (2013), the goal of each study was to identify the most beneficial of interactive instruction. However, as there is the possibility for improvement in any…
