Objectives (5 - 7 minutes)

1. Understand the concept of nature and its importance for life on Earth. Students should be able to identify examples of natural elements around them and understand how these elements contribute to ecological balance.
2. Recognize the need to conserve nature and natural resources. Students should understand that nature provides essential resources for human life, such as air, water, food, building materials, among others, and that it is everyone's responsibility to protect and preserve these resources.
3. Identify attitudes and practices that contribute to nature conservation. Students should be able to identify simple actions they can take in their daily lives to help preserve nature, such as saving water and energy, recycling waste, not polluting the environment, among others.

Introduction (10 - 12 minutes)

1. Recalling contents: The teacher starts the lesson by reminding students about the concept of the 'environment' and its importance for life on Earth. Simple questions like 'What is the environment?' and 'Why is it important to take care of the environment?' can be asked. (2 - 3 minutes)

2. Problem situations: The teacher presents two situations that will arouse students' interest and guide them to the lesson's topic. The first situation could be: 'Imagine you are in a park and see someone littering. What would you do?' The second situation could be: 'What if you were at home and saw someone wasting water, what would you do?' (3 - 4 minutes)

3. Contextualization: The teacher explains that these situations are related to our topic today, which is nature conservation. For example, he can say that littering or wasting water are actions that harm nature and that we all must do our part to protect it. Additionally, the teacher can mention real examples of environmental problems that children may know, such as deforestation and river pollution. (2 - 3 minutes)

4. Capturing students' attention: The teacher presents two curiosities about nature that will arouse students' interest. The first curiosity could be: 'Did you know that a single tree can produce enough oxygen for a family of four to breathe for a year?' The second curiosity could be: 'And did you know that the plastic we throw away can take hundreds of years to decompose in nature?' (3 - 4 minutes)

Development (20 - 25 minutes)

During this stage, the teacher should present content related to nature conservation. The goal is for students to acquire solid knowledge on the subject, in order to understand the importance of nature and the need to preserve it. Below are three possible activities suggested for this stage, from which the teacher can choose the one that best suits his class.

1. Nature Memory Game

   • The teacher should prepare a memory game in advance with cards containing images of nature elements (animals, plants, rivers, mountains, clouds, etc.) and cards with images of actions that can interfere with nature conservation (deforestation, pollution, fires, water wastage, etc.).
   • Students, divided into small groups, will receive the cards face down and, each time they turn a card, they must say whether the element on the card is part of nature or an action that harms nature. If the answer is correct, the student/group keeps the card. Otherwise, they return it to its place.
   • The game continues until all cards are turned. The group with the most cards wins.
   • During the game, the teacher should take the opportunity to talk to the students about the importance of nature elements and how each action can affect them.

2. Creation of the 'Nature Museum'

   • The teacher divides the class into groups and provides art materials (such as paper, colored pencils, pens, scissors, and glue).
   • Each group is tasked with creating a 'display' with images and drawings of nature elements that, in their opinion, are the most important to be preserved.
   • After creating the displays, each group presents their 'nature museum' to the class, explaining why they made their choices and the importance of preserving these elements.
   • During the presentations, the teacher can reinforce the concepts of nature conservation and the importance of each element for life on Earth.

3. Puppet Theater 'Nature Guardians'

   • The teacher suggests that students, divided into groups, create a puppet story about the importance of taking care of nature.
   • Each group should choose one or two 'nature guardians' and create a story in which these characters teach the importance of preserving nature and how each person can contribute to it.
   • After creating the stories, the groups present their shows to the class, reinforcing the message of nature conservation.
   • During the presentations, the teacher can pause to remind students of the concepts learned and reinforce the importance of each one in nature conservation.

It is important for the teacher, when choosing one of the activities, to adapt it according to the class's needs and the available resources. Additionally, he should be attentive to clarify doubts and promote the participation of all students.

Return (10 - 15 minutes)

1. Group Discussion (5 - 7 minutes): The teacher gathers all students for a group discussion. During this discussion, each group will have the opportunity to share with the class what they learned or created during the development activities. The teacher can ask questions like: 'What did you discover about the importance of nature conservation?', 'Which actions do you think are most important for nature conservation?' and 'How can you help conserve nature at home and at school?' The teacher should listen carefully to the students' answers, encouraging everyone's participation and promoting an environment of respect and appreciation for each other's ideas. (2 - 3 minutes for each group)

2. Connection with Theory (3 - 5 minutes): After the discussion, the teacher makes the connection between the practical activities carried out and the theory presented at the beginning of the lesson. He can recall the key concepts discussed, emphasizing how the activities helped to better understand these concepts. For example, if the memory game was the chosen activity, the teacher can say: 'Remember when we played the memory game? You were able to identify which actions harm nature and which nature elements are important for life on Earth. This is very important for us to understand how we can contribute to nature conservation.' (2 - 3 minutes)

3. Final Reflection (2 - 3 minutes): To conclude the lesson, the teacher proposes that students make a brief reflection on what they have learned. He can ask two simple questions to help students in this reflection: 'What was the most interesting part you discovered today about nature and its conservation?' and 'What could you do from now on to help conserve nature?' Students will have a minute to think about these questions and, if they wish, can share their answers with the class. The teacher should encourage students to think about their actions and how they can contribute to nature conservation. (1 minute for each question)

Throughout the return, the teacher should maintain a welcoming and respectful environment, valuing each student's contributions and reinforcing the importance of nature conservation. Additionally, the teacher should be attentive to clarify any doubts that may arise and to correct any misconceptions students may have.

Conclusion (5 - 7 minutes)

1. Summary (2 - 3 minutes): The teacher starts the conclusion by recalling the main points covered during the lesson. He can emphasize the definition of nature and how it is essential for life on Earth. Additionally, he can emphasize the importance of nature conservation and why everyone, including children, should contribute to this cause. The teacher can then recap some of the attitudes and practices that were discussed during the lesson and that help conserve nature, such as saving water, recycling, not polluting the environment, among others. (1 - 2 minutes)

2. Connecting Theory with Practice (1 - 2 minutes): The teacher explains how the lesson connected theory with practice. He can say, for example, that the memory game, creation of the 'Nature Museum,' and puppet theater activities allowed students to apply theoretical concepts of nature conservation in a playful and interactive way. Additionally, the teacher can mention how group discussions and final reflections helped students better understand the importance of nature conservation and how they can contribute to it. (1 minute)

3. Extra Materials (1 - 2 minutes): The teacher suggests some extra materials for students who wish to deepen their knowledge on the subject. These materials may include books, videos, educational games, and reliable websites. For example, the teacher can recommend the book 'The Giving Tree' by Shel Silverstein, which tells the story of a tree that gives everything it has to a boy who grows around it, as a way to illustrate the concept of nature's generosity. Additionally, the teacher can suggest the website 'Sustainable Planet,' which offers a series of educational games and activities on nature conservation. (1 minute)

4. Importance of the Subject (1 minute): Finally, the teacher highlights the importance of the subject for students' daily lives. He can say, for example, that nature conservation is not just a task for adults, but that everyone, including children, can and should contribute to it. Additionally, the teacher can mention how simple actions that students learned in the lesson, such as saving water and recycling, can make a big difference for the environment. (1 minute)

Throughout the conclusion, the teacher should reinforce the importance of nature conservation and the responsibility that each one has to protect and preserve the environment. Additionally, he should encourage students to continue learning and acting sustainably in their daily lives.
