The Riddle Activity is an engaging, interactive classroom exercise designed to reinforce students' understanding of Microbes in Human Welfare through critical thinking and teamwork. Students work in groups to solve creative riddles that describe the roles of various microbes in areas such as agriculture, industry, sewage treatment, and bioenergy.

Each riddle presents clues about a specific microbe or microbial process, challenging students to decipher the microbe’s identity based on its functions and applications in real life. Teams collaborate to discuss the riddle, apply their knowledge, and submit their answers, fostering both content comprehension and collaborative skills.

This activity not only encourages problem-solving and discussion but also connects the biological content to real-world applications. Through the process of riddles, students engage in deeper learning about how microbes benefit society—whether by producing biogas, aiding in fermentation, or acting as biofertilizers
