SLCC’s First Physiology Symposium

Which Coca-Cola product is better for your cardiovascular system, regular, diet or Mexican Coke? That was one of the questions posed by students in the Human Physiology Lab (BIO 2425) whose posters were showcased for the first Physiology Symposium at the Taylorsville Redwood and Jordan campuses earlier this month. 

The course is a hands-on lab where students investigate physiological processes through data and analysis of the cardiovascular, respiratory, digestive, endocrine, immune and muscular systems. Students created a plan and used the scientific method to carry out experiments. They collected and analyzed the data and created figures to explain how the data supports their hypotheses. This symposium prepared many of them to have experience in undergraduate research, even if some of the outcomes didn’t go as planned.

“Implementing a course-based undergraduate research experience increases undergraduate involvement in research and helps students achieve a deeper understanding of human physiology,” says Evelyn Mendoza Galvez, Biology Lab coordinator. “Inquiry helps the student build the understanding necessary to generate deeper learning, and there is as much value in experiences that don’t go as planned as in those that do.”

Working in groups of up to five students, they came up with a question that had personal interest to them and then researched the topic and constructed a hypothesis. Some of the questions students came up with were how the different types of Coca-Cola affected the cardiovascular system, between morning or evening exercise which is more effective, and how breathing exercises and meditation improved mental health.

“I feel like a lot of students in college struggle with anxiety and depression. It's just interesting to find ways to bring down your anxiety so we thought this would be a cool project,” said Addison Marshall, a student who presented at the symposium.

One of the methods her group chose was box breathing, a four-step breathing technique that involves breathing in, holding the breath, and breathing out for the same number of counts. They tested students before and after to see how the breathing affected their mental states. “This project made this class more interesting. It didn’t just feel like a science fair project that you had to do. I learned a lot as well,” she said.

This semester students were able to use new equipment to conduct their experiments such as a treadmill and lactate measuring devices that were purchased with a $68,000 award that the department received at the end of spring semester.

One group used the new treadmill to test their hypothesis and see what the effects of pre-workouts were on heart rates, and another group measured Basal Metabolic Rate (BMR) using a Total Body Composition Analyzer scale and also tested lactic acid levels using the new lactate device to see the effect that exercise has on BMR in the body.

“Our hope in creating this project-based learning opportunity was to provide students with the experience to learn physiology on a deeper level with a fun and creative approach.” Jo Stosich, biology lab instructor says she found students doing just that. “They immersed themselves in their projects and showed excitement in the process.”

All students in the class were required to do this assignment as part of their grade, however, presenting at the symposium was optional, though they had a large number of students who participated. The project spans the course of the semester and is a “rigorous” process according to Jo. But she adds that “our students stepped up to the challenge and surpassed our expectations.”

Winners for best poster

Friday event winners: Martin Bigatii, Abby Johnson, Lauren Linan, Christine Melvin and Mike Reilly with their poster entitled, "The Effects of Breathing on Heart Rate, Blood Pressure, and Respiratory Rate After Exercise."  

Monday event winners: Karamel Azadnia, Harley Bright, Mark Long, Savannah Palmer, and Dylan Troy with their poster entitled, "The Effect of Body Fat Percentage on Blood Lactate During Aerobic Exercise."

Rev Up Your Future at SLCC Annuals Hop into College

SLCC West Valley Center will be opening its doors on Friday, August 2, from 6-9 pm for their annual lowrider event that celebrates the automotive culture and welcomes current, past, and future Bruins into the SLCC community. This unique event allows lowriders to showcase their vehicles and for spectators to witness the creativity, craftsmanship, and passion that goes into a lowrider car. From the sleek custom paint jobs to the impressive hydraulics showcased at the hop-off, attendees get immersed in the vibrant culture created by SLCC West Valley’s community. Beyond the car show, Hop into College provides prospective students and their families the opportunity to explore SLCC, engage with their future peers, staff and faculty and obtain valuable insight into the degrees and programs offered. Furthermore, the community is provided with countless beneficial resources not only as an SLCC student but as a community member. Whether interested in learning more about the lowrider community o...

The Center for Prior Learning Receives an Honorable Mention

Today, SLCC's Credit for Prior Learning department received an Honorable Mention from the  Council for Adult and Experiential Learning (CAEL ) and the  Western Interstate Commission for Higher Education  for its intentional approach and for expanding student options to receive credit for prior learning.  Credit for Prior Learning (CPL)  allows students to obtain college credit for knowledge and skills acquired outside of the traditional academic environment. This is exceptionally beneficial for adult learners, who, according to CAEL, have a 17% higher chance of graduating compared to those adults who don’t earn credits through prior learning programs. The CPL department at SLCC was created in 2020 and since then the volume of students served has grown as the department continues to expand. To be eligible for CPL, students must be working towards a degree, certificate, or apprenticeship. Director of Credit for Prior Learning at SLCC, Andrea Tipton, mentioned fee...

Board of Higher Ed names Gregory F. Peterson 9th SLCC President

The Utah Board of Higher Education unanimously selected Gregory F. Peterson, Ed.D., as the ninth president of Salt Lake Community College today, following an extensive national search. Peterson will assume the position on July 1, 2024, and succeeds Deneece G. Huftalin, who served as president from 2014-2024.   “I’m humbled by the opportunity to serve as Salt Lake Community College’s next president, and I look forward to reinforcing SLCC’s commitment to providing educational pathways for transfer and workforce that improve the lives of every member of our community,” Peterson said. “SLCC has an amazing future ahead, and I couldn’t be prouder to be a part of that journey.”   As part of its delegated duties and responsibilities, the SLCC Board of Trustees named an  11-member committee  in December 2023 to conduct a national search for the next president of SLCC. The committee is composed of representatives from the Utah Board of Higher Education and SLCC trustees, facul...
