Objectives (5 - 7 minutes)

1. Understand the definition of tissues in the human body and their importance in the structure and function of the organism.
2. Identify and describe the four main types of tissues (epithelial, connective, muscular, and nervous), including their characteristics, functions, and locations in the human body.
3. Establish the relationship between the structure and function of each type of tissue, with practical and applicable examples.

Secondary objectives:

• Foster students' research and critical thinking skills by encouraging them to seek additional information on the topic.
• Develop oral and written communication skills through group discussions and the production of summaries or reports on the topics covered.
• Encourage autonomous learning by providing students with the opportunity to study the topic in advance and bring questions and reflections to class.

Introduction (10 - 15 minutes)

1. Review of Previous Content: The teacher will begin the class by conducting a brief review of the concepts of the cell, the level of cellular organization, and the systems of the human body. This review will serve to prepare students for the new content by recalling the basic structure of the organism and situating tissues as a higher level of organization. (3 - 5 minutes)

2. Contextualization: Next, the teacher will present two problem situations to pique students' interest. The first situation could be that of an athlete who suffers a muscle injury and needs to understand how muscle tissue recovers and regenerates. The second situation could be that of a person with a skin burn who needs to understand the healing process and how epithelial tissue works in this process. These situations will introduce the importance of tissues in the functioning and recovery of the human body. (4 - 6 minutes)

3. Relevance of the Subject: The teacher will highlight the importance of studying tissues for understanding the functioning of the human body and for practicing medicine. It will be explained how the understanding of tissues is essential for the identification and treatment of various diseases and injuries, and how the knowledge acquired in this class can be applied to medical practice. (2 - 3 minutes)

4. Introduction to the Topic: To arouse students' curiosity, the teacher will share two curiosities about tissues. The first curiosity could be that the human body is made up of trillions of cells, but these cells are not isolated, they are organized into tissues, which in turn form the organs and systems of the body. The second curiosity could be about the regenerative capacity of some tissues, such as epithelial tissue, which is constantly renewed, or muscle tissue, which can regenerate after an injury. (2 - 4 minutes)

Development (20 - 25 minutes)

1. Classification Activity (10 - 12 minutes):

   • The teacher will divide the class into groups of up to five students and give each group a set of cards. Each card will contain a description of a type of tissue (epithelial, connective, muscular, and nervous) without mentioning the name of the tissue.
   • The objective of the activity is for the students, in their respective groups, to identify the type of tissue to which the description refers, and to classify the cards into four categories corresponding to the four types of tissues.
   • The descriptions on the cards should include structural characteristics, function, and location in the human body.
   • After classification, each group will present their conclusions to the class, justifying their choices and discussing with the other groups.

2. Concept Map Building Activity (10 - 12 minutes):

   • Using the same division into groups, the teacher will propose an activity to build a concept map on tissues.
   • Each group will receive a sheet of large colored paper, pens, and stickers.
   • The teacher will suggest that the students place the type of tissue in the center of the map, and around it, place the characteristics, functions, and locations.
   • Students are encouraged to use different colors, drawings, and symbols to make the map visually appealing and easy to memorize.
   • After building the map, the groups will present their work to the class, explaining the logic of their organization and how the information is connected.

3. Discussion Activity (if time permits) (5 - 7 minutes):

   • If time permits, the teacher may propose a discussion activity where students will have the opportunity to debate the importance of studying tissues for medical practice, for example.
   • The teacher may present some dilemmas or complex cases related to tissues and ask the students to discuss them in their groups, presenting their conclusions to the class.
   • This activity will stimulate critical thinking, argumentation, and the ability of students to work in teams.

Feedback (10 - 12 minutes)

1. Group Discussion (5 - 6 minutes):

   • The teacher will gather all the students and open a classroom discussion. Each group will have a maximum of 3 minutes to share the solutions or conclusions they reached during the classification and concept map building activities.
   • During the discussion, the teacher should ask questions to stimulate students' critical thinking and deepen their understanding of the topic. For example, the teacher might ask: "Why do you think epithelial tissue is found on the outer surface of the body and in internal organs?", "How does the structure of muscle tissue relate to its function of movement?".
   • The teacher can also ask students to provide practical examples or everyday situations that illustrate the function or importance of each type of tissue.

2. Connection with Theory (3 - 4 minutes):

   • After the discussion, the teacher will summarize, connecting the activities carried out with the theory presented in the Introduction of the class. The teacher will reinforce the key concepts, clarify possible doubts, and explain how the practical activities helped to deepen students' understanding of the topic.
   • The teacher can revisit the problem situations presented in the Introduction and ask students if they can answer them more fully now, after exploring the topic.

3. Final Reflection (2 - 3 minutes):

   • To conclude the class, the teacher will propose a moment of reflection. Students will be invited to think silently for a minute and then share their answers to the following questions:
     1. What was the most important concept you learned today?
     2. What questions have not yet been answered?
   • The teacher will collect the students' answers and use these reflections to plan the next classes and adjust the pedagogical approach, if necessary.
   • This final reflection helps students to consolidate what they have learned and to identify areas that need further study or clarification.

4. Teacher Feedback (1 minute):

   • Finally, the teacher will provide general feedback on the class's participation and performance during the class, highlighting the positive points and areas that need improvement. The teacher can also take this opportunity to reinforce important points and clarify any confusion that may have arisen during the class.

Conclusion (5 - 8 minutes)

1. Content Summary (2 - 3 minutes):

   • The teacher will summarize the main points covered in the class, reinforcing the key concepts about the four types of tissues in the human body. It will be recalled:
     1. The definition of tissues and their importance in the structure and function of the human body.
     2. The characteristics, functions, and locations of epithelial, connective, muscular, and nervous tissues.
     3. How the structure of each tissue is closely linked to its function.
   • The teacher can use a chart or a slide to visualize these points and make it easier for students to understand.

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

   • The teacher will explain how the activities carried out in class helped to connect theory with practice. It will be highlighted how the classification of the cards and the construction of the concept map allowed students to visualize and better understand the characteristics, functions, and locations of tissues.
   • The teacher can also emphasize how the group discussion and the final reflection allowed students to apply theoretical knowledge to practical situations and deepen their understanding of the topic.

3. Supplementary Materials (1 - 2 minutes):

   • The teacher will suggest supplementary study materials for students who wish to further deepen their knowledge of tissues. These materials may include textbooks, scientific articles, educational videos, websites from research institutions and universities.
   • The teacher can make a list of these materials available on the school's virtual learning platform for easy student access.

4. Relevance of the Subject (1 minute):

   • Finally, the teacher will emphasize the importance of studying tissues for understanding the functioning of the human body and for practicing medicine. It will be reinforced that knowledge about tissues is essential for the identification and treatment of various diseases and injuries.
   • The teacher can cite practical examples of how knowledge about tissues is applied in medical practice, such as in the diagnosis of cancer through tissue biopsies, or in the repair of muscle injuries through specific rehabilitation exercises.
