Lesson Summary: In this lesson, students engaged in a structured debate to address the question, "Are microorganisms more helpful or harmful?" applying their knowledge to a real-world argument while developing critical thinking and communication skills. The lesson began with a review of the dual roles of microorganisms, highlighting examples such as probiotics in digestion and bacteria causing illness. Students were divided into teams, assigned a position to defend, and used research from articles, videos, and class notes to gather evidence for their argument. Each team prepared opening statements, supporting points, and rebuttals to address counterarguments. During the debate, students presented their positions, defended their claims with evidence, and responded to opposing viewpoints, practicing respectful discourse. The lesson concluded with a class reflection on the complexity of microorganisms and how they impact daily life. This activity fostered a deep understanding of the topic while promoting collaboration, persuasive reasoning, and real-world application of scientific concepts.
