: The Human Physiology Laboratory (BIO 2425) is the laboratory portion to accompany Human Physiology (BIO 2420). Some colleges offer these as one combined course. At Snow College they are separated into two courses taken concurrently. Together they cover the topics in sufficient detail to provide the scientific foundation for further study in allied health professions and biological professions. BIOL 2425 will be comparable to Human Physiology Labs offered by other Utah System of Higher Education institutions.For the natural sciences, science is the systematic inquiry into natural phenomena organizing and condensing those observations into testable models and hypotheses, theories, or laws. The success and credibility of science is anchored in the willingness of scientists to: 1) expose their ideas and results to independent testing and replication by other scientists which requires the complete and open exchange of data, procedures, and materials; 2) abandon or modify accepted conclusions when confronted with more complete or reliable experimental evidence. Adherence to these principles provides a mechanism for self-correction that is the foundation of the credibility of science. (Adapted from a statement by the Panel on Public Affairs of the American Physical Society which was endorsed by the Executive Board of the American Association of Physics Teachers in 1999.) While properties of matter and energy in the physical sciences are common to life science, the emergent properties resulting from the complexities of life require additional study to amplify and clarify the molecular mechanisms of nature.General Education Outcomes
1: A student who completes the GE curriculum will have a fundamental knowledge of human cultures and the natural world, with particular emphasis on American institutions, the social and behavioral sciences, the physical and life sciences, the humanities, the fine arts and personal wellness. The primary purpose of this course is to give students a hands-on, practical learning experience that supports the concurrent BIOL 2420 class. The exercises are meant to facilitate a strong conceptual understanding of such biological principles as simple chemistry, cell structure and function, metabolism, homeostasis, mitosis and meiosis, biological information flow from DNA to RNA to protein (central dogma), function of organs and systems to maintain life. Students must be able to constructively and critically evaluate the text and laboratory manual written descriptions of physiologic processes and instructions in order to successfully complete the laboratory exercises. Student success will be assessed through class participation, written lab assignments/reports, quizzes and exams.
2: A student who completes the GE curriculum can read, retrieve, evaluate, interpret, and deliver information using a variety of traditional and electronic media. Lab reports include writing components in which the student, after conducting laboratory exercises, expresses his or her understanding of physiologic processes. Assessment includes written lab assignments, quizzes, and exams.
6: A student who completes the GE curriculum can reason analytically, critically, and creatively about nature, culture, facts, values, ethics, and civic policy. Students will demonstrate scientific reasoning throughout the various topics considered in course content for the laboratory in their responses to lab reports, quizzes, lab discussions, and exams.Student Learning Outcomes:
Students will study some of these concepts in the laboratory setting by applying the scientific method including collecting and analyzing data and drawing conclusions. Emphasis will be placed on hands-on experimentation and/or exercises. Problem-solving exercises, lab work sheets/assignments, practical quizzes and class participation in discussion groups will be utilized in assessing student learning. At least one exam (final) will also be administered in this lab.
Laboratory exercises and experiments will be utilized to further examine how the human body functions to maintain itself in a living condition when there are forces in the natural world that oppose that condition. Topics such as diet and nutrition, the immune system, environmental quality and pollution, etc. may be among those topics discussed. Course focus is not on issues but rather the application of scientific principles to assist in the resolution of problems exemplified by issues. Students will be assessed through practical quizzes, written lab reports and assignments, class participation, and exams.
Not all information available on the internet, or in written form, or spoken, is of equal validity. Labs are developed from peer-reviewed journals as well as faculty research. Reading and working through the laboratory exercises gives students practical experience to aid in the evaluation of scientific information. Class discussions, short answer questions on quizzes, lab exercises and exams will be utilized to ascertain student’s comprehension of scientific principles.
Laboratory experiments provide opportunities to make careful observations, collect and analyze data, and draw conclusions relevant to key biological concepts. Students are given opportunities to demonstrate both their experience in and mastery of laboratory skills in lab reports, quizzes, and exams.
