Objectives (5 - 10 minutes)

1. Identify and differentiate the main types of water present on the Earth's surface: oceans, seas, rivers, lakes, and lagoons.
2. Understand the importance and role of water in the formation and maintenance of terrestrial ecosystems.
3. Develop critical thinking and analytical skills when discussing the impacts of human activities on global hydrography.

Secondary objectives:

• Stimulate students' curiosity and interest, encouraging them to explore more about the topic outside the classroom.
• Promote the understanding that water is a valuable natural resource that needs to be preserved and managed sustainably.
• Develop research and presentation skills by asking students to find real examples of how human activities affect hydrography.

Introduction (10 - 15 minutes)

1. Concept review: The teacher should start the lesson by quickly reviewing the concepts of physical geography previously discussed, focusing on those related to the formation of the Earth's surface and the importance of water. This review may include concepts such as the water cycle, hydrographic basins, and the role of water in terrestrial ecosystems. (3 - 5 minutes)

2. Presentation of problem situations: Next, the teacher should present two situations that will arouse students' curiosity and serve as a basis for Theory Development. The situations can be:

   • The first situation could be the description of a small village in an arid region facing a severe water shortage. The teacher can ask students what they think could have caused this situation and how it could be resolved.
   • The second situation could be the description of a coastal city suffering from sea invasion due to rising sea levels. The teacher can ask students about the possible impacts of this on the local population's life and what could be done to prevent or mitigate these impacts. (4 - 6 minutes)

3. Contextualization: The teacher should then explain the importance of studying hydrography, relating it to real and current situations. For example, the teacher may mention the importance of water for human life and ecosystem maintenance, and the challenges that water scarcity and climate change are bringing to various parts of the world. (2 - 3 minutes)

4. Introduction of the topic: Finally, the teacher should introduce the lesson topic in an engaging and interesting way. For example, they can tell the story of how the oceans were formed and how they influence the planet's climate. Or they can talk about the 'river in the sea,' a rare phenomenon that occurs in the Atlantic Ocean and consists of a powerful flow of fresh water moving along the sea surface. (3 - 4 minutes)

Development (20 - 25 minutes)

1. Activity 'Discovering Hydrography' (10 - 15 minutes)

   • Class division: The teacher should divide the class into groups of up to five students. Each group will receive a world map and colored markers.
   • Activity objective: The objective of this activity is for students to identify and mark on the map the main oceans, seas, rivers, lakes, and lagoons in the world. They should also identify the continents and countries that have the largest extension of water or the highest number of water bodies.
   • Activity realization: The teacher should provide students with a list of the names and locations of the main water bodies in the world. The students should then research and mark these water bodies on the world map. They can also use different colors of markers to represent the different types of water. For example, blue for oceans, seas, rivers, and lakes, and green for lagoons.
   • Discussion and presentation: After completing the activity, each group should present their map to the class, explaining their color choices and highlighting some of the most significant water bodies they marked. The teacher should facilitate a discussion on the importance of these water bodies for life on Earth and for ecosystem maintenance.

2. Activity 'The Role of Water' (10 - 15 minutes)

   • Activity organization: The teacher should continue with the same groups from the previous activity. Each group will receive a set of cards, each describing a different situation related to water.
   • Activity objective: The objective of this activity is for students to discuss and identify the type of water body that would be most relevant to solve the situation described on the card.
   • Activity realization: Students should read the situations and discuss in their groups which type of water body (oceans, seas, rivers, lakes, or lagoons) would be most appropriate for the described situation. They should justify their choices based on what they learned in class.
   • Discussion and Conclusion: After the discussion, each group should present some of their situations and their justifications to the class. The teacher should lead a discussion on the different answers and why certain water bodies are more suitable for solving certain situations than others.

3. Activity 'Human Impacts on Hydrography' (optional - if time allows) (5 - 10 minutes)

   • Activity organization: The teacher should continue with the same groups from the previous activity. Each group will receive a set of cards, each describing a human activity that can impact hydrography.
   • Activity objective: The objective of this activity is for students to discuss and identify the possible impacts of these activities on hydrography and ecosystems.
   • Activity realization: Students should read the activities and discuss in their groups what could be the impacts of these activities on hydrography. They should justify their answers based on what they learned in class.
   • Discussion and Conclusion: After the discussion, each group should present some of their activities and the possible impacts to the class. The teacher should lead a discussion on the different answers and the importance of considering the impacts of human activities on hydrography and ecosystem sustainability.

The teacher should circulate around the classroom, assisting the groups, clarifying doubts, and encouraging everyone's participation. At the end of the activities, the teacher should briefly recap the concepts and main points discussed. (5 - 10 minutes)

Return (10 - 15 minutes)

1. Group Discussion (5 - 7 minutes)

   • The teacher should gather all students and promote a general discussion about the solutions or conclusions found by each group during the activities.
   • The goal is for students to have the opportunity to share their ideas, questions, and discoveries with each other, thus enriching everyone's learning.
   • The teacher should encourage students to explain the reasoning behind their choices and offer constructive feedback to their peers.
   • During the discussion, the teacher should emphasize the importance of critical thinking and argumentation skills, which were developed during the activities.

2. Connection with Theory (3 - 5 minutes)

   • After the discussion, the teacher should review the main theoretical concepts covered in the lesson and relate them to the practical activities carried out.
   • For example, the teacher can recall the importance of oceans in regulating the global climate and ask students to make connections with the 'Discovering Hydrography' activity.
   • Similarly, the teacher can highlight the importance of freshwater for life on Earth and ask students to relate this to the 'The Role of Water' activity.
   • The teacher should reinforce that the practical understanding of theoretical concepts is essential for effective and lasting learning.

3. Individual Reflection (2 - 3 minutes)

   • To conclude the lesson, the teacher should propose that students reflect individually on what they have learned.
   • The teacher can ask questions like: 'What was the most important concept you learned today?' and 'What questions have not been answered yet?'.
   • Students should be encouraged to write down their answers in a notebook or on a piece of paper, as this reflection can help them consolidate their learning and identify areas that still need clarification.
   • The teacher should remind students that these questions can be discussed in the next lesson or that they can seek the teacher for more information or clarification.
   • The teacher should encourage students to continue exploring the topic outside the classroom, whether through additional readings, internet research, or real-world observations.

4. Feedback (optional)

   • If time allows, the teacher can request feedback from students about the lesson. This can be done through oral questions or a written questionnaire. Student feedback can provide valuable information to the teacher about what worked well in the lesson and what may need to be adjusted for future classes.

The Return is an essential stage of the lesson plan, as it allows the teacher to assess students' progress, clarify remaining doubts, and identify areas that may need reinforcement in future classes. Additionally, it provides students with a final opportunity to reflect on their learning, consolidate their knowledge, and develop metacognitive skills.

Conclusion (5 - 10 minutes)

1. Summary and Recapitulation (2 - 3 minutes)

   • The teacher should give a brief summary of the main points covered during the lesson. They should recall the definition and characteristics of the main types of water (oceans, seas, rivers, lakes, and lagoons), the importance of water for life on Earth and for ecosystem maintenance, and the impacts of human activities on global hydrography.
   • This is an opportunity for the teacher to reinforce the most important concepts and clarify any doubts that may have arisen during the practical activities.

2. Theory-Practice Connection (1 - 2 minutes)

   • The teacher should then explain how the lesson connected theory with practice, referring to the activities carried out. They should highlight how the identification and discussion of water bodies on the map helped students understand the distribution and importance of water on Earth, and how the analysis of situations and human activities led them to reflect on the impacts of these activities on hydrography and ecosystems.

3. Extra Materials (1 - 2 minutes)

   • The teacher should suggest some extra materials for students who wish to deepen their knowledge on the topic. These materials may include books, articles, documentaries, environmental organizations' websites, among others.
   • For example, the teacher can recommend the book 'The Sea Around Us' by Rachel Carson, which explores the importance of water for life on Earth, or the documentary 'Chasing Ice,' which discusses the impact of climate change on glaciers and sea levels.

4. Relevance of the Subject (1 - 2 minutes)

   • Finally, the teacher should emphasize the importance of studying hydrography for students' daily lives. They can mention, for example, how hydrography influences the climate, vegetation, and biodiversity of a location, and how it affects the availability of drinking water and the occurrence of natural disasters.
   • The teacher should also emphasize the importance of preserving and sustainably managing water resources, given the water scarcity in many parts of the world and the impacts of climate change on global hydrography.
   • By doing this, the teacher helps students understand the relevance of what they have learned and develop environmental awareness.

The Conclusion is a crucial stage of the lesson plan, as it allows the teacher to consolidate students' learning, reinforce the importance of the topic, and motivate them to continue exploring the subject. Additionally, it provides students with a final opportunity to clarify any remaining doubts and reflect on what they have learned.
