Introduction (10 - 15 minutes)

1. Review of Previous Content: The teacher should start the lesson by reminding students of concepts related to the environment and sustainability that were covered in previous classes. This may include discussions on the importance of biodiversity, the need to conserve natural resources, and the effects of pollution.

2. Problem Situations: The teacher can present two problem situations to stimulate students' critical thinking. The first situation may involve the pollution of the Ganges River in India, one of the most sacred rivers in the world, and the impacts of this pollution on the lives of people who depend on the river for drinking, cooking, and religious rituals. The second situation may involve the accelerated deforestation in Indonesia to make way for palm oil plantations, and the effects of this on local biodiversity and the global climate.

3. Contextualization: The teacher should emphasize the importance of studying environmental problems in Asia, explaining that Asia is the most populous continent in the world and that many of the environmental challenges faced there are representative of global challenges. In addition, the teacher can explain how solving these problems can contribute to improving people's quality of life and protecting the planet.

4. Gaining Attention: To capture students' attention, the teacher can share curiosities and interesting facts about Asia and its environmental problems. For example, the teacher can mention that Asia is the continent with the largest number of megacities, which are cities with more than 10 million inhabitants, and how rapid urbanization in these cities has contributed to air pollution and soil degradation. Another curiosity could be the importance of Asia for global biodiversity, with ecosystems like the Amazon Rainforest and the Great Barrier Reef.

   • Solutions to Environmental Problems in Asia (3 - 4 minutes): The teacher should present some of the solutions that are being proposed and implemented to address these challenges. This may include the adoption of cleaner technologies, the promotion of sustainability in agriculture, and the strengthening of biodiversity conservation policies.

2. Group Discussion (5 - 7 minutes):

   • Group Organization (1 - 2 minutes): The teacher should divide the class into groups of up to 5 students. Each group will receive a problem situation related to the topics discussed in the lesson. The problem situations may include, for example, the creation of a soil protection policy in a degraded area in China, or the implementation of a recycling program in a megacity in India.
   • Analysis of Problem Situations (3 - 4 minutes): Students should discuss the problem situations in groups, identify the main challenges, and propose solutions. The teacher should move around the room, guiding the discussions and clarifying doubts.
   • Presentation of Proposals (1 - 2 minutes): Each group should present their proposals to the class. The teacher should encourage the participation of all students and promote an environment of respect and cooperation.

3. Practical Activity (5 - 6 minutes):

   • Document Analysis (3 - 4 minutes): The teacher should distribute a set of documents (articles, graphics, maps, etc.) related to environmental problems in Asia to each group. Students should analyze the documents in their groups and prepare a brief presentation for the class, highlighting the main findings and reflections.
   • Presentation of Analyses (2 - 3 minutes): Each group should present their analyses to the class. The teacher should facilitate the discussion by asking questions that encourage students to think critically and connect theory with practice.

4. Feedback and Closure (2 - 3 minutes):

   • Feedback (1 - 2 minutes): The teacher should provide feedback to students on their presentations and discussions, praising good work and providing constructive suggestions for improvements.
   • Closure (1 minute): The teacher should end the lesson by summarizing the main points discussed and reinforcing the importance of studying environmental problems in Asia and possible solutions.

Return (8 - 10 minutes)

1. Connection to the Real World (3 - 4 minutes): The teacher should encourage students to reflect on how the concepts learned in the lesson relate to the world around them. This can be done through questions such as:

   • How do environmental problems in Asia affect the lives of people living there? And how do they affect the lives of people on other continents?
   • Can you identify similarities between environmental problems in Asia and the problems in your own community? And differences?
   • What actions can you take, as individuals and as members of a community, to help solve or mitigate environmental problems in Asia and the world?

2. Reflection on Learning (3 - 4 minutes): The teacher should suggest that students reflect on what they learned during the lesson. This can be done through questions such as:

   • What was the most important concept you learned today? Why?
   • What questions have not been answered yet? What would you like to learn more about regarding environmental problems in Asia?
   • How can you apply what you learned today in other situations or disciplines?

3. Feedback for the Teacher (2 minutes): The teacher should ask students for feedback on the lesson. This can be done through questions such as:

   • What did you think of today's lesson? What worked well and what could be improved?
   • Do you feel that the learning objectives were achieved? Why?
   • Do you have any suggestions for future lessons or activities?

4. Closure (1 minute): The teacher should end the lesson by thanking the students for their participation, reinforcing the importance of studying environmental problems in Asia, and reminding them of the next topic or task.

This Return is a crucial step to consolidate students' learning, promote reflection and metacognition, and adjust the teacher's practice for future lessons. Therefore, it is important for the teacher to dedicate time and attention to this step.
