##### Introduction (10 minutes)
1. **Greeting and Attendance (2 minutes)**:
- Briefly greet students and take attendance.
2. **Warm-Up Activity (3 minutes)**:
- Begin with a quick question: "What do you think 'evolution' means?"
- Encourage a few students to share their thoughts.
3. **Objective Overview (2 minutes)**:
- Outline the learning objectives of the lesson.
- Inform students that today's lesson will explore different theories of evolution, with a focus on understanding their fundamental concepts.
4. **Hook Activity (3 minutes)**:
- Show a short video clip or animation about the diversity of life and how species have evolved over time.

##### Instruction (30 minutes)
1. **Lecture and Discussion**:
- **Charles Darwin’s Theory of Natural Selection (10 minutes)**:
- Describe Darwin’s theory and key concepts like "survival of the fittest" and "adaptation."
- Give examples like the Galapagos finches.
- **Jean-Baptiste Lamarck’s Theory of Inheritance of Acquired Traits (5 minutes)**:
- Explain Lamarck’s theory and why it is no longer widely accepted.
- Use examples such as the elongation of giraffe necks.
- **Modern Synthesis (5 minutes)**:
- Introduce the Modern Synthesis combining Darwin’s natural selection with Mendelian genetics.
- Discuss the role of mutations, gene flow, and genetic drift.
- **Other Theories (10 minutes)**:
- Briefly cover other concepts like punctuated equilibrium by Gould and Eldredge.
- Discuss the concept of convergent evolution.
- **Q&A Session (5 minutes)**:
- Open the floor for questions from students to clarify any doubts.

##### Activity (30 minutes)
1. **Group Activity**:
- **Instructions (5 minutes)**:
- Divide the class into small groups of 4-5 students.
- Assign each group a different theory of evolution to research and prepare a brief presentation.
2. **Research and Preparation (10 minutes)**:
- Allow groups to use textbooks, handouts, and internet resources to gather information.
- Provide chart paper and markers for creating visual aids.
3. **Group Presentations (15 minutes)**:
- Each group will present their assigned theory with key points, visual aids, and examples.
- Encourage other students to ask questions after each presentation.

##### Review and Conclusion (15 minutes)
1. **Summary (5 minutes)**:
- Summarize the key points discussed during the lesson.
- Reiterate the importance of understanding these evolutionary theories.
2. **Class Discussion (5 minutes)**:
- Engage students in a discussion about the impact of evolutionary theories on modern science and society.
- Ask students to provide examples of how knowledge of evolution is applied today.
3. **Assessment (5 minutes)**:
- Distribute a short, formative quiz or ask for an exit ticket with one question: "Which theory of evolution do you find most compelling and why?"
---
##### Homework:
1. **Assignment**:
- Ask students to write a one-page essay comparing Darwin’s theory of natural selection with another evolutionary theory.
- Include at least one real-world example to support their discussion.
---
##### Additional Notes:
- **Students should bring their textbooks and writing materials to class.**
- **Ensure all students have equal access to research materials.**
- **Provide extra support to students who may struggle with the material.**
#### Follow-Up:
- **In the next class, review the essays and discuss common themes and interesting insights.**
- **Plan for a deeper dive into the mechanisms of evolution, such as genetic drift and gene flow.**
