Development (20 - 25 minutes)

Activity 1: Skin Layers Model

• The teacher divides the students into groups of five.
• Each group receives a small, labeled diagram of the skin, showing the epidermis, dermis, and hypodermis.
• The teacher hands out materials for creating a model of the skin layers: playdough or clay for the epidermis, paper or fabric for the dermis, and cotton or sponge for the hypodermis.
• Students are instructed to work together to create their skin models, paying attention to the different layers and their functions.
• During the activity, the teacher circulates the room, guiding the students as needed, and asking questions to ensure understanding.
• After completing the models, each group presents its model, explaining the role of each layer and how they work together.

Activity 2: Sweat Gland Experiment

• For this experiment, the teacher provides each group with a piece of clear plastic wrap, a rubber band, a small amount of water, and a dropper or pipette.
• Students are instructed to create a "sweat gland model" using these materials. They tightly wrap the plastic around a small area of one person's wrist, securing it with the rubber band.
• The person whose wrist is wrapped then uses the dropper to place a drop of water inside the plastic wrap, representing sweat being released.
• The group observes and discusses what happens to the "sweat" inside the plastic wrap. The teacher encourages them to think about how this process is related to the body's temperature regulation.
• Each group presents their findings and conclusions from the experiment.

Activity 3: Hair and Nail Investigation

• In this activity, each group will examine hair and nail samples using a hand lens or microscope, if available.
• The teacher provides hair and nail samples, which can be collected from different students, under supervision, to ensure safety and hygiene.
• Students are instructed to make careful observations of the hair and nails, noting any similarities and differences.
• The teacher encourages the students to discuss their findings, guiding their attention to the structures they can see and how they might be related to the integumentary system's functions.
• After the investigation, each group reports on their observations and conclusions.

Activity 4: Skin Health Poster

• The final activity allows students to apply their knowledge creatively. Each group is tasked with creating a poster that promotes healthy practices for the skin, hair, and nails.
• The teacher provides art supplies such as markers, colored pencils, glue, and construction paper for the posters.
• The students are encouraged to include information they learned about the integumentary system, as well as practical tips for maintaining its health.
• After the posters are completed, each group presents their poster to the class, explaining the information and tips they included.

Throughout these activities, the teacher should facilitate discussions, encourage critical thinking, and ensure that all students are engaged. The hands-on nature of these activities will help students to understand and remember the functions and structures of the integumentary system in a fun and interactive way.

Feedback (7 - 10 minutes)

1. Group Discussion and Reflection

   • The teacher invites each group to share their solutions, conclusions, and observations from the activities. Each group is given up to 2 minutes to present.
   • After each presentation, the teacher facilitates a short discussion, asking other students to share their thoughts, and encouraging them to make connections between the presented group's findings and the concepts discussed during the lesson.
   • The teacher ensures that each group has an opportunity to present and receive feedback, fostering a supportive and respectful learning environment.

2. Connecting Activities with Theory

   • After all groups have presented, the teacher summarizes the key points from the activities, linking them back to the theory of the integumentary system.
   • The teacher underscores how the hands-on activities helped the students to understand the structure and functions of the skin, hair, and nails, and how these components work together to form the integumentary system.
   • The teacher emphasizes the importance of the integumentary system and how its health affects overall well-being, highlighting the real-world applications discussed at the beginning of the lesson.

3. Individual Reflection

   • The teacher asks the students to take a moment to reflect on what they have learned in the lesson. The teacher can guide this reflection by asking thought-provoking questions:
     1. "What was the most important concept you learned today about the integumentary system?"
     2. "Which of your group's findings or conclusions surprised you the most?"
     3. "How will you apply what you learned today about the integumentary system in your daily life, for example in taking care of your own skin, hair, and nails?"

4. Feedback Collection

   • The teacher collects the students' reflections, either by having them write down their answers or by conducting a brief oral discussion. This feedback will help the teacher gauge the students' understanding and identify any areas that may need further clarification in future lessons.

5. Closing Remarks

   • The teacher concludes the feedback session by praising the students for their active participation and their efforts in understanding the complex topic of the integumentary system.
   • The teacher reinforces the importance of the integumentary system and encourages the students to continue exploring and learning about the human body in future lessons.
