### **Lesson Procedure**:
**1. Introduction (10 minutes)**:
- **Engage**: Begin with a short discussion asking students what they know about habitats and ecosystems.
- **Explain**: Define key terms:
- **Ecosystem**: A community of living organisms interacting with their environment.
- **Habitat**: The natural environment where an organism lives.
- Use a projector to show images of different ecosystems and briefly describe each one.
**2. Direct Instruction (15 minutes)**:
- **Teach**: Discuss the characteristics of various habitats:
- **Forest**, **Desert**, **Ocean**, **Grassland**, and **Tundra**.
- **Highlight**: Talk about the specific plants and animals found in each habitat.
- Use the smartboard to show real-life examples or short videos illustrating each habitat.
**3. Guided Practice (20 minutes)**:
- Hand out worksheets that feature different habitats.
- **Activity**: Students will match pictures of animals and plants to their correct habitats.
- Walk around to assist students and answer questions as they complete the activity.
- Facilitate a sharing session where students present their matches to the class.
**4. Independent Practice (10 minutes)**:
- **Drawing Activity**: Have students draw their favorite habitat and include plants and animals they learned about.
- Ask students to write a few sentences about why they chose that habitat and what they find interesting about it.
**5. Conclusion (5 minutes)**:
- **Summarize**: Review the main points of the lesson.
- **Discuss**: Talk about the importance of protecting ecosystems and what can happen when habitats are destroyed.
- **Reflection**: Encourage students to think about one thing they can do to help protect ecosystems.
**6. Assessment**:
- Collect and review the habitat worksheets and drawings to assess understanding.
- Use oral questioning during the lesson to gauge comprehension.

**Differentiation**:
- For advanced learners: Challenge them to research an ecosystem not covered in class and present to their peers.
- For struggling learners: Provide additional visuals and one-on-one support during activities.
**Homework**:
- Assign students to find a picture of an ecosystem in a magazine or online, cut it out, and bring it to the next class. They will share with the class why they chose that ecosystem.

**Additional Resources**:
- Books: "Exploring Ecosystems" series by Pam Marshall or "Habitats" by Laura Purdie Salas.
- Websites: National Geographic Kids, BBC Earth for Kids.
