Abstract:
We have designed an interactive, inquiry-driven collaborative activity tailored for students with varying background in biology to investigate the concepts of Microbiology. Through this exercise, students learn the intricacies of yogurt fermentation, and then explore how different factors like temperature, substrate, and inoculant source can influence the process. Results are assessed both qualitatively, by examining characteristics such as smell and appearance, and quantitatively, using viscosity measurements. Students combine and analyze their data to present their conclusions orally. This activity can be performed in any part of the world, so it is suitable for remote labs and institutions lacking specialized equipment.
Keywords:
Hands-on, Remote Lab, Microbiology
Outcomes:
Master the fundamentals of setting up experimental assays like yogurt fermentation while work aseptically.
Generate a hypothesis, design and execute an experiment considering the necessity of replicates and controls.
Collectively gather, analyze, interpret, and orally present the data relating the findings to the current scientific literature.
