Comprehend what vitamins and minerals are:
- The teacher should explain the concept of vitamins and minerals, differentiating them and highlighting their origin and classification.
- Students should actively participate, asking questions and discussing their doubts and understanding of the topic.
-
Understand the importance of vitamins and minerals to the human body:
- The teacher should relate the functions of different types of vitamins and minerals in the metabolism and overall functioning of the human body.
- Students should be encouraged to research and share information about the role of these nutrients in human health and well-being.
-
Know the possible effects of deficiency and excess of these nutrients in the human body:
- The teacher should present cases of diseases caused by deficiency or excess of vitamins and minerals, emphasizing the importance of a balanced diet.
- Students should be encouraged to research nutritional diseases and discuss ways to prevent them through proper nutrition.
Secondary Objectives:
- To promote the students' understanding of the relationship between diet and health.
- To encourage research and debate among students, developing their research and argumentation skills.
Introduction (10 - 15 minutes)
-
Recall necessary content:
- The teacher should start the class by recalling previous biochemistry concepts, such as the basic constitution of cells, and the role of nutrition in health and disease.
-
Suggest problem situations:
- Present the situation of a person who has a diet rich in processed foods and poor in natural nutrients, asking students what the health consequences for that person could be.
- Propose the situation of a person who takes vitamin supplements without medical advice, questioning the students about possible adverse effects.
-
Contextualize the importance of the subject:
- The teacher should emphasize the importance of understanding vitamins and minerals in making healthy food choices, preventing diseases, and maintaining overall health.
-
Introduce the topic in an interesting way:
- The teacher can tell the story of the discovery of vitamins and how their deficiency led to diseases that were previously unknown, such as scurvy in sailors due to lack of vitamin C.
- Another interesting curiosity is to talk about the minerals that are essential for the functioning of the human body, such as iron, which is fundamental for the transport of oxygen in cells.
During the introduction, students should be actively involved in the discussion, asking questions, giving their opinions, and raising hypotheses about the problem situations presented. They should also write down the important information and key concepts presented for later reference.
Development (20 - 25 minutes)
-
Playful Activity: "Vitamins and Minerals Game"
- The teacher should divide the class into groups of no more than 5 people. Each group will receive a list of foods and a list of vitamins and minerals.
- The objective of the game is for students to research and match the correct foods to their respective vitamins and minerals.
- After completing the game, the groups should present their findings to the class, explaining what they discovered and how.
- During the presentation, the teacher should correct any errors and clarify any misunderstandings.
-
Research Activity: "Effects of Nutrient Deficiency and Excess"
- Keeping the groups from the previous activity, the teacher will provide a list of symptoms and diseases associated with deficiency or excess of certain vitamins and minerals.
- Students should research and match the correct symptoms and diseases to the respective vitamins and minerals.
- After completing the research, each group should present their findings to the class, explaining what they discovered and how.
- During the presentation, the teacher should correct any errors and clarify any misunderstandings.
-
Discussion Activity: "Diets and Supplements"
- The teacher should start a classroom discussion about the importance of a balanced diet and the risks associated with the misuse of vitamin and mineral supplements.
- Students should be encouraged to share their opinions, personal experiences, and knowledge acquired during the research activities.
- The teacher should moderate the discussion, providing additional information when necessary and ensuring that all students have the opportunity to participate.
During all development activities, students should be encouraged to work in teams, actively research, ask questions, and participate in discussions. They should also write down the important information and key concepts presented for later reference.
Return (8 - 10 minutes)
-
Group Presentations (3 - 5 minutes):
- The teacher should invite each group to briefly share their conclusions about the activities carried out.
- Each group will have a maximum of 3 minutes to talk about their findings, emphasizing the most important and interesting points.
- During the presentations, the other students should pay attention and can ask questions or make comments after each presentation.
-
Connection with Theory (2 - 3 minutes):
- After all the presentations, the teacher should tie the groups' conclusions with the theoretical concepts presented at the beginning of the class.
- The teacher should highlight how the practical activities helped illustrate and deepen the understanding of the functions of vitamins and minerals and the consequences of their deficiency or excess.
-
Final Reflection (3 - 4 minutes):
- The teacher should then ask the students to spend a minute silently reflecting on what they learned in class.
- After the individual reflection, the teacher should ask some questions to the class, such as:
- What was the most important concept learned today?
- What questions have not yet been answered?
- Students should be encouraged to share their reflections, giving them the opportunity to express what they learned, which concepts are still unclear, and which areas they would like to explore further.
During the feedback stage, the teacher should pay attention to the students' answers and reflections, noting any gaps in understanding that can be addressed in future classes. It is also important for the teacher to reinforce the main concepts and learning from the class, as well as the relevance of the subject to the students' daily lives.
Conclusion (3 - 5 minutes)
-
Content Summary (1 - 2 minutes):
- The teacher should recap the key concepts learned during the class, emphasizing the definition and importance of vitamins and minerals, the effects of their deficiency or excess on the human body, and the importance of a balanced diet.
- Students should pay attention and jot down any points they may have missed or need to review later.
-
Connection between Theory and Practice (1 minute):
- The teacher should reinforce how the practical activities and classroom discussions helped illustrate and deepen the understanding of the theoretical concepts presented.
- Students should be encouraged to reflect on how theory and practice complemented each other during the class and how this contributed to their learning.
-
Suggestions for Extra Materials (1 - 2 minutes):
- The teacher should suggest complementary readings, videos, websites, or apps that can help students study the subject in more depth.
- Students should write down the suggestions for extra materials and be encouraged to explore them in their free time.
-
Importance of the Subject to Everyday Life (1 minute):
- Finally, the teacher should reinforce the relevance of the concepts learned to the students' daily lives, highlighting the importance of healthy food choices for maintaining health and preventing diseases.
- Students should be encouraged to think about how they can apply what they learned in class to their own lives, such as when making food choices or when thinking about the need (or not) for vitamin and mineral supplements.
At the end of the class, students should have a clear understanding of the concepts presented, as well as where to find additional study materials and how to apply the acquired knowledge in their daily lives. The teacher should be available to answer any remaining questions and to clarify any points of confusion that may have arisen.
