From washing hands before meals to brushing teeth after meals, these daily practices protect our bodies from harmful agents and promote well-being.

Curiosities and Market Connection

Did you know that the profession of microbiologist is directly related to the study of microorganisms and how they affect our health? Additionally, in the job market, health professionals, such as doctors and nurses, emphasize the importance of hygiene habits to prevent the spread of diseases in hospitals and clinics.

Initial Activity

Begin the class by asking the students: 'Do you know how many microorganisms are on our hands right now?' Then show a short video that illustrates the number of germs present on common objects and how washing hands can help eliminate them (video duration: 2-3 minutes).

Development

Duration: (45 - 55 minutes)

The purpose of this stage is to deepen students' understanding of the importance of hygiene habits through practical and reflective activities. The mini challenge and fixation exercises aim to consolidate acquired knowledge, allowing students to apply the information in real-life situations and develop relevant skills for the future.

Covered Topics

1. Importance of hygiene habits in disease prevention
2. Main microorganisms present in our daily lives
3. Daily personal hygiene practices
4. How microorganisms cause diseases

Reflections on the Theme

Guide students to reflect on how small daily actions, such as washing hands and brushing teeth, can have a significant impact on health. Ask: 'If we didn't wash our hands before eating, what could happen?' or 'Why is it important to brush our teeth after meals?' Encourage them to think of examples from their own lives where hygiene has helped them avoid diseases.

Mini Challenge

Building a Homemade Microscope

Build a simple microscope using household materials to observe the number of microorganisms present on different surfaces.

Instructions

1. Divide the students into groups of 4-5.
2. Distribute the materials: magnifying glass, cardboard tubes, adhesive tape, glass slides, and a light source (flashlight or natural light).
3. Ask the students to assemble the microscope following the instructions: Fix the magnifying glass at the end of the cardboard tube with adhesive tape.
4. Guide the students to collect samples from different surfaces (e.g., unwashed hands, doorknobs, tables) and place them on the glass slides.
5. Use the flashlight or natural light to illuminate the sample and observe through the homemade microscope.
6. Ask the students to draw what they observe and share with the class.
7. Lead a discussion on the observed results and the importance of hygiene practices to reduce the presence of microorganisms.

Objective: Demonstrate practically the presence of microorganisms in our environment and the importance of hygiene practices to avoid diseases.

Duration: (30 - 35 minutes)

Evaluation Exercises

1. Draw two hygiene practices that you perform every day and explain why they are important.
2. In groups, create a list of five essential hygiene habits and share with the class.
3. Answer: What could happen if we didn't wash our hands regularly? Give examples.

Conclusion

Duration: (10 - 15 minutes)

The purpose of this stage is to consolidate students' learning, providing a moment for reflection and synthesis of the content addressed. Through discussion and summarization, students can internalize the importance of hygiene habits and understand how to apply this knowledge in their daily lives and future professions.

Discussion

Promote an open discussion with the students about the topics covered during the class. Ask: 'What did we learn today about microorganisms and hygiene habits?' Encourage students to reflect on the homemade microscope mini challenge and share their observations and conclusions. Ask: 'How can the practice of washing hands prevent diseases?' and 'Do you think these practices are important only for children or also for adults?' Stimulate students to give examples of how they can apply the acquired knowledge in their daily routines and future work environments.

Summary

Summarize and recapitulate the main content presented in the class, such as the importance of hygiene habits, the types of microorganisms that can be found in our daily lives, and daily personal hygiene practices to prevent diseases. Reinforce the connection between theory and practice, highlighting how the homemade microscope activity helped visualize the presence of microorganisms and the importance of hygiene practices.

Closing

Explain how the class connected theory, practice, and applications, emphasizing the importance of hygiene habits for health and well-being. Conclude by highlighting that hygiene is not only a personal practice but also a collective responsibility that impacts public health. Thank the students for their participation and reinforce the importance of applying the acquired knowledge in their daily routines.
