4. Creating a Mutation Story: Now, each group must imagine a scenario where their assigned character faces a mutation. They should consider what type of mutation it might be, how it could occur, and what changes it could cause in the character. The group should document their mutation story as a narrative or a comic strip. They should also speculate how this mutation could affect the character's life and their relationships with others. (8 minutes)

5. Presentation & Discussion: After all the groups have completed their mutation stories, each group presents their character, the type of mutation they faced, and the changes it caused. The class then discusses the presented mutations, their plausibility, and the potential impacts they could have on the characters. The teacher facilitates the discussion, ensuring that accurate scientific information is being shared and encouraging students to think critically about the mutations. (8 minutes)

Activity Two: "Mutation Investigation" (10 - 12 minutes)

1. Problem Introduction: The teacher presents a problem to the class, explaining that a new species of animal has been discovered, but there are some concerns. The animal has an unusual color pattern, and some of them are getting sick. The students are tasked with investigating whether these observations could be a result of genetic mutations. (2 minutes)

2. Investigation Process: The students continue working in their groups. They are provided with a worksheet that guides them through the investigation process. They must use the knowledge gained from the reading assignment and the video to complete the worksheet. The worksheet includes questions like "What type of mutation could cause the unusual color pattern?" and "What type of mutation could cause the sickness?". (5 minutes)

3. Presentation & Discussion: Each group presents their conclusions to the class. The teacher encourages the class to provide feedback and ask questions about the presented mutations. This will promote a deeper understanding of mutations and how they can be investigated. (5 minutes)

By the end of these activities, the students should have a clear understanding of genetic mutations, their types, and their potential impacts. They will have practiced critical thinking, collaboration, and problem-solving skills in a fun and engaging way.
