A hands on educational module to teach aspects of human dietary health using fruit flies as a model |
|
|||
This module highlights an exercise to explore a variety of biological processes related to human nutrition and related health issues. The module capitalizes on the tremendous amount of knowledge on the life cycle, physiology, genetics, and behavior of Drosophila melanogaster to investigate the effects of diet on development, survival, behavior, environmental stressors, and physiological functions such as heart rate and neural-muscular function with sensory-motor integration. Students and teachers can develop their own flavor to the modules with exploration in the effect from various available mutations in Drosophila. Many stock lines are available which relate to human diseases providing the potential for students to pursue a wide-range of inquiries on human-related diseases such as diabetes and Metabolic Syndrome. This unit contains pedagogical support to assist teachers with facilitating open inquiry to acquire new knowledge. The interdisciplinary nature of the investigations provides opportunities for diverse connections to address authentic research questions related to diet and health in model invertebrate organisms. This module is presented in a variety of ways to be readily modified depending on equipment available in the classroom and the academic level of students. The modules were designed to be used in a hybrid or remote format with data provided or collected by in class participants. ABLE hand out for presentation (MS word or PDF) Power point slides of presentation (ppt) |
