1. General understanding of the human reproductive system: The first objective is for students to develop a solid and comprehensive understanding of the human reproductive system, including its components, functions, and how they interact.

2. Identification and description of the parts of the reproductive system: Next, students should be able to identify and describe the different parts of the reproductive system, both male and female. This includes understanding the anatomy, role, and function of each part.

3. Understanding the process of human reproduction: Finally, students should be able to explain the process of human reproduction, including the production of reproductive cells, fertilization, and the development of a new human being.

Secondary Objectives:

1. Understanding the differences between the male and female reproductive systems: In addition to the core objectives, students should also be able to identify and describe the differences between the male and female reproductive systems.

2. Discussion about reproductive health and contraception: Students should be encouraged to discuss issues related to reproductive health and contraception, as well as the importance of consent and sexual education. This can help contextualize the topic and make it more relevant to students' own lives.

Introduction (10 - 15 minutes)

1. Review of related content (3 - 5 minutes): The teacher should begin the lesson by reminding students about the concepts of cells, reproduction, and heredity, as these are fundamental to understanding the human reproductive system. It is important for students to have a solid foundation in these topics before moving on.

2. Problem situation 1 - "The mysterious pregnancy" (3 - 5 minutes): The teacher should present an intriguing problem situation, such as the case of women who did not know they were pregnant until they were in labor. This situation will serve to spark students' curiosity and lead them to question how the human reproductive system works and how it is possible for a woman not to notice the signs of pregnancy.

3. Problem situation 2 - "The mystery of heredity" (3 - 5 minutes): Next, the teacher can introduce another intriguing case, such as parents who have very different physical characteristics from their children. This situation can lead them to question how genetic characteristics are passed down from one generation to the next and the importance of the reproductive system in this process.

4. Contextualization (2 - 3 minutes): The teacher should explain the importance of studying the human reproductive system, highlighting how this knowledge can impact health, decision-making, and our understanding of the world around us. The teacher can provide examples of how human reproduction and genetics affect our everyday lives, such as in choosing partners, understanding inheritable diseases, and the importance of sex education and contraception.

5. Attention grabber (1 - 2 minutes): To grab students' attention, the teacher can share some fun facts about the human reproductive system. For example, they could mention that the human body produces about 200 million sperm cells per day or that the egg cell is the largest cell in the human body, being visible to the naked eye. These fun facts can help create a fun and engaging learning environment.

Development (20 - 25 minutes)

1. Activity 1 - "Building the Reproductive System" (10 - 12 minutes):

   • In this activity, students will be divided into groups of up to 5. Each group will receive materials such as modeling clay, straws, rubber bands, paper, and glue.
   • The task will be to build, in a three-dimensional way, the human reproductive system, including all its parts (testes, penis, ovaries, uterus, fallopian tubes, etc.). The teacher should provide reference images and descriptions of each part to assist in the construction.
   • During the activity, students will be encouraged to discuss among themselves and with the teacher about the functions and interactions of each part of the reproductive system, consolidating the knowledge acquired in the Introduction phase.
   • After completing the construction, each group will present their model to the class, explaining the different parts and their functions. The teacher should lead a discussion to correct any misconceptions and clarify any doubts.

2. Activity 2 - "The Journey of the Egg" (10 - 12 minutes):

   • In this activity, students will remain in the same groups. The teacher will provide a large sheet of paper, colored pens, and stickers.
   • The task will be to draw the "Journey of the Egg", from its production in the ovary to its possible fertilization in the uterus. Students should represent the different stages with drawings and brief descriptions.
   • During the activity, the teacher should circulate around the room, observing the groups' work and providing guidance and clarification, if necessary.
   • After completing the drawings, each group will present their "Journey of the Egg" to the class, explaining each stage. The teacher should lead a discussion to correct any misconceptions and clarify any doubts.

3. Activity 3 - "Debate: Sex Education in Schools" (5 - 6 minutes):

   • After completing the previous activities, the teacher should propose a debate about the importance of sex education in schools.
   • Students will be divided into two groups: one group defending the idea that sex education should be part of the school curriculum from an early age, and the other group arguing that this type of education should be the sole responsibility of the family.
   • Each group will have a set time to present their arguments and counter-argue the opposing group's points. The teacher should act as a moderator, ensuring that the debate is respectful and productive.

By the end of the Development, students will have had the opportunity to explore the human reproductive system in a practical and contextualized way, understanding its parts and functions, and discussing relevant and current issues about sex education.

Return (8 - 10 minutes)

1. Group Discussion (3 - 5 minutes): The teacher should gather all the students and promote a group discussion about the solutions or conclusions reached by each team. This is an opportunity for students to share the different approaches they used to solve the activities and for the teacher to clarify any misconceptions or misunderstandings that may have arisen.

2. Connection to Theory (2 - 3 minutes): Next, the teacher should make the connection between the practical activities carried out and the theory presented at the beginning of the lesson, reinforcing the key concepts of the human reproductive system. This can be done by highlighting how the activities helped students understand the structure and function of the reproductive system, as well as the process of human reproduction. The teacher can also reiterate the importance of the reproductive system for human life and genetics.

3. Individual Reflection (2 - 3 minutes): Finally, the teacher should propose that students reflect individually on what they learned in the lesson. To do this, the teacher can ask the following questions:

   1. What was the most important concept you learned today?
   2. What questions have not yet been answered?
   3. How can you apply what you learned today in your daily life?
   • Students should have a minute to think about each question. The teacher can ask some students to share their answers with the class, which can help identify any areas that need further clarification or practice.
