### Engagement (10 minutes)
**Activity: Think-Pair-Share**
1. **Think**: Students will take 2 minutes to think about how they impact the environment daily (e.g., using plastic, energy consumption).
2. **Pair**: Students will pair up and share their thoughts for 3 minutes.
3. **Share**: Each pair will then share one example of their human impact with the class.
### Exploration (15 minutes)
**Activity: Video and Discussion**
1. **Watch**: Play a short documentary (5-7 minutes) on human impact on the environment and sustainability efforts (e.g., "The Story of Stuff").
2. **Discuss**: Lead a classroom discussion based on the video:
- What are the main human activities that impact the environment?
- How do these activities affect ecosystems and biodiversity?
- What are some sustainable practices presented in the video?
### Explanation (15 minutes)
**Activity: Interactive Presentation**
1. **Human Impact**:
- Discuss key concepts such as pollution, deforestation, carbon footprint, and global warming.
- Explain the direct and indirect effects of these activities on the planet.
2. **Sustainability**:
- Introduce the principles of sustainability and sustainable living.
- Highlight the importance of conservation and the use of renewable resources.
### Elaboration (10 minutes)
**Activity: Case Studies**
1. Provide students with short case studies of communities or companies that have successfully implemented sustainable practices.
2. In pairs, students will read and analyze the case studies, then answer the following:
- What sustainable practices were used?
- How did these practices benefit the environment and the community?
### Evaluation (10 minutes)
**Activity: Sustainability Action Plan**
1. **Assignment**:
- Individually, students will brainstorm and jot down ideas for a sustainability project they can implement in their school or community (e.g., recycling program, energy-saving campaign).
2. **Sharing**:
- Allow a few students to share their ideas with the class.
- Encourage feedback and suggestions from peers.
### Closure (5 minutes)
**Recap and Reflection**
1. Summarize the key points discussed in the lesson.
2. Encourage students to reflect on their own habits and how they can adopt more sustainable practices.
3. Assign homework: Write a short essay on the importance of sustainability and one actionable change they will make to reduce their carbon footprint.
