Description
There has long been a link tied between obesity and such pathological conditions as nonalcoholic fatty liver disease and type two diabetes. Studies have shown that feeding rats a diet high in fat results in hepatic steatosis and steatohepatitis. Using a novel short term diet of six weeks with male adolescent Sprague-Dawley rats, our laboratory sought to investigate the early effects of high fat intake on the liver. Prior findings in our laboratory found that a high fat diet (HFD) leads to nonalcoholic fatty liver disease as well as other symptoms of metabolic syndrome. This study hypothesized that rats fed a 60% HFD for 6 weeks, unlike a high sucrose or standard chow diet, would have an elevated expression of pro-inflammatory cytokines associated with steatohepatitis. TNF-α, TLR4 and XBP1 were chosen for their link to hepatic inflammation. The results of this study found that contrary to the hypothesis, the high fat diet did not induce significant changes in the expression of any inflammatory marker in comparison to a high sucrose or control chow diet.

There is still a major underrepresentation of females in STEM fields, with many girls beginning to lose interest as early as middle school. This is due to a variety of factors including lack of role models, stereotypes, ineffective teaching methods, and peer influence. A popular way to increase female interest is through day camps and other programs where girls complete a variety of activities related to science and engineering. These activities are usually designed around problem-based learning, a student-lead approach to teaching that requires students to work collaboratively and use background knowledge to solve some sort of given problem. In this project, a day camp for middle school girls was created and implemented to increase student interest in STEM through three problem-based learning activities. By analyzing survey data, it was concluded that the camp was successful in increasing interest and changing participants' attitudes towards science. This approach to learning could be applied to other subject areas, including mathematics, to increase the interest of both male and female students at the secondary level.

Description
The Downtown ASU campus Bio 201 and 202 anatomy labs are planning on revising the method in which students are presented and evaluated on lab material for the Fall 2016 semester. The goal of this thesis project was to analyze the methods used in previous semesters in order to determine which method, if any, proved to be the most effective means of evaluation for the students. The general setup of the anatomy labs is that the students come to lab, receive that week's instruction, and then are quizzed on that week's material at the beginning of their next lab. Then roughly every five new segments there is a practical covering the cumulative information from the last five segments. Therefore it is imperative to analyze the current and previous methods of evaluation in order to find which one has the strongest correlation with an individual's quiz performance and their practical grade. Since the Fall 2014 semester three different quiz types have been used in lab while the practical has remained the same. The three different types of quizzes are written, turning point, and no quiz; in order to determine which method was most effective overall practical averages for each student was compared to their corresponding quiz average. This data was put into Excel and used to generate a graph in order to determine the r-squared values to determine which had the strongest correlation. The results showed that no matter what quiz type was used there was no statistically significant correlation between quiz performance and practical performance; in fact practical averages were nearly identical between semesters for Bio 201 and 202. However, visual analysis of the graph demonstrated that certain quiz methods did seem to be more effective than others. For Bio 201 it seemed that written quizzes were the most effective means of evaluation, while in Bio 202 the turning point quizzes were best.

There are two types of understanding when it comes to learning math: procedural understanding and conceptual understanding. I grew up with a rigorous learning curriculum and learned math through endless drills and practices. I was less motivated to understand the reason behind those procedures. I think both types of understanding are equally important in learning mathematics. Procedural fluency is the "ability to apply procedures accurately, efficiently, and flexibly... to build or modify procedures from other procedures" (National Council of Teachers of Mathematics, 2015). Procedural understanding may perceive as merely about the understanding of the arithmetic and memorizing the steps with no understanding but in reality, students need to decide which procedure to use for a given situation; here is where the conceptual understanding comes in handy. Students need the skills to integrate concepts and procedures to develop their own ways to solve a problem, they need to know how to do it and why they do it that way. The purpose of this 5-day unit is teaching with conceptual understanding through hands-on activities and the use of tools to learn geometry. Through these lesson plans, students should be able to develop the conceptual understanding of the angles created by parallel lines and transversal, interior and exterior angles of triangles and polygons, and the use of similar triangles, while developing the procedural understanding. These lesson plans are created to align with the eighth grade Common Core Standards. Students are learning angles through the use of protractor and patty paper, making a conjecture based on their data and experience, and real-life problem solving. The lesson plans used the direct instruction and the 5E inquiry template from the iTeachAZ program. The direct instruction lesson plan includes instructional input, guided practice and individual practice. The 5E inquiry lesson plan has five sections: engage, explore, explain, elaborate and evaluate.

Description
Experiential learning is the process of gaining new information by participating in some sort of experience. One way this can occur inside the classroom, as in the inquiry model or problem-based learning. It can also occur outside of the classroom, as in outdoor education or field trips. Recently, virtual experiential learning opportunities have surfaced, including virtual field trips, experiments, and manipulatives. This project aims to define experiential learning, including examples in every context. Then, it describes current elementary school teachers' perceptions of experiential learning via survey results. The final product also includes an Appendix which is made up of experiential learning lesson plans for each context.

Description
The specific focus of the curriculum guide is to encourage inquiry and exploration of sustainability with middle school students. Children need to be explicitly taught how to analyze findings, how to work together, and teachers need to begin to lay the foundation of finding ideal solutions that best serve all people. The sooner that we introduce our students to these concepts in conjunction with science concepts the better prepared they will be to face the upcoming challenges and the better developed their scientific literacy.

Description
Birds have unusually high plasma glucose concentrations compared to mammals of similar size despite their high metabolic rate. While birds use lipids as their main source of energy, it is still unclear how and why they maintain high plasma glucose concentrations. To investigate a potential underlying mechanism, this study looks at the role of lipolysis in glucose homeostasis. The purpose of this study is to examine the effects of decreased glycerol availability (through inhibition of lipolysis) on plasma glucose concentrations in mourning doves. The hypothesis is that decreased availability of glycerol will result in decreased production of glucose through gluconeogenesis leading to reduced plasma glucose concentrations. In the morning of each experiment, mourning doves were collected at the Arizona State University Tempe campus, and randomized into either a control group (0.9% saline) or experimental group (acipimox, 50mg/kg BM). Blood samples were collected prior to treatment, and at 1, 2, and 3 hours post-treatment. At 3 hours, doves were euthanized, and tissue samples were collected for analysis. Acipimox treatment resulted in significant increases in blood glucose concentrations at 1 and 2 hours post- treatment as well as renal triglyceride concentrations at 3 hours post-treatment. Change in plasma free glycerol between 0h and 3h followed an increasing trend for the acipimox treated animals, and a decreasing trend in the saline treated animals. These results do not support the hypothesis that inhibition of lipolysis should decrease blood glycerol and blood glucose levels. Rather, the effects of acipimox in glucose homeostasis appear to differ significantly between birds and mammals suggesting differing mechanisms for glucose homeostasis.

Description
As we count down the years remaining before a global climate catastrophe, ever increases the importance of teaching environmental history and fostering environmental stewardship from a young age. In the age of globalization, nothing exists in a vacuum, yet our traditional education system often fails to reflect the abundant connections between content areas that are prevalent outside of schools. In fact, many of the flaws of the field of education have been exacerbated by the COVID-19 pandemic and a forced transition to online schooling, with many educators reverting to outdated practices in a desperate attempt to get students through the year. The aim of this project was to design a unit curriculum with these issues in mind. This month-long environmental history unit engages students through the use of hands-on activities and promotes interdisciplinary connections. The unit can be taught in a physical, online, or hybrid American history class, and will hopefully inspire and motivate students to become environmental stewards as they look toward their futures on this planet.

Description
This study aims to produce efficient and effective group writing workshops for students within the Barrett Honors College at Arizona State University. To balance two opposing theories in writing center pedagogy - the direct instruction theory and the student-led/ collaborative theory - this study also aims to determine whether a balanced combination of these approaches in writing workshops will increase student confidence in their writing abilities. Several writing workshops were held over Zoom utilizing a combination of direct teaching methods and collaborative techniques. Students were then surveyed to determine whether they found the workshops helpful, learned new skills, and/or grew more confident in their abilities. The student responses proved the hypothesis that a combined approach leads to an increase in student confidence.
