4. Introduction to the Topic: To introduce the topic and capture students' attention, the teacher can share some curiosities or interesting facts about acid nomenclature.

   • Curiosity 1: "Did you know that acid nomenclature was developed by chemists from ancient Greece and Rome?"
   • Curiosity 2: "Did you know that acid nomenclature can vary depending on where you are in the world? For example, acetic acid is known as vinegar in cooking, but in the chemical industry, it is often called ethanoic acid."

Throughout the Introduction, the teacher should encourage students to ask questions and actively participate in the discussion, ensuring that everyone has a solid understanding of the topic before moving on to the next steps.

Development (20 - 25 minutes)

1. "Guess the Acid" Activity: (10 - 15 minutes)

   • Description: The teacher will divide the class into groups of up to 5 students and give each group a set of cards. Each card should contain the molecular formula of an acid (e.g., H2SO4) or the name of an acid (e.g., sulfuric acid). The goal of the activity is for each group to "guess" the name of the acid from the formula, or the formula from the name, using their knowledge of acid nomenclature. The first group to correctly "guess" earns a point. The group with the most points at the end of the activity wins.

   • Step-by-step:

     1. The teacher should explain the rules of the activity and how points will be counted.
     2. Each group receives the set of cards and starts "guessing" the names of the acids from the formulas (or vice versa).
     3. The teacher circulates around the room, observing the progress of the groups, answering questions, and providing guidance if necessary.
     4. When a group correctly "guesses," they can score a point.
     5. After a set time, the teacher interrupts the activity and counts the points. The group with the most points is the winner.

2. "Create Your Acid" Activity: (10 - 15 minutes)

   • Description: In this activity, students will have the opportunity to create their own acids and name them using the nomenclature rules they learned. The teacher will provide each group with a water solution (H2O) and a selection of simple elements and compounds (e.g., hydrogen, oxygen, sulfur, carbon) for them to use. The goal is for students to create a formula for their acid and then name it correctly.

   • Step-by-step:

     1. The teacher should explain the rules of the activity and provide each group with the necessary materials.
     2. Students, in their groups, should start experimenting with the combination of elements and compounds to create a formula for their acid.
     3. Once they have a formula, they should use the naming rules to name their acid.
     4. The teacher circulates around the room, observing the progress of the groups, answering questions, and providing guidance if necessary.
     5. When all groups have created and named their acids, they will have the opportunity to share their creations with the class. The teacher can discuss the nomenclature of each acid, highlighting common mistakes and reinforcing the correct rules.

During the Development, the teacher should be active in facilitating the activities, circulating around the room, giving guidance, answering questions, and providing feedback. The teacher should also ensure that all students are engaged and actively participating in the activities.

Return (10 - 15 minutes)

1. Group Discussion: (5 - 7 minutes)

   • Description: The teacher will gather the class and promote a group discussion to share the solutions and conclusions of each group. Each group will have a limited time (e.g., 2 minutes) to briefly present what they discovered or created during the activities. The teacher should facilitate the discussion by asking questions to promote critical thinking and deepen students' understanding.

   • Step-by-step:

     1. The teacher gathers the class and explains that each group will have the opportunity to share their solutions or conclusions.
     2. The teacher calls each group in turn and gives them a limited time (e.g., 2 minutes) to briefly present what they discovered or created during the activities. The teacher may ask students to focus on explaining the process they used to name the acids, rather than just giving the final answer.
     3. After each presentation, the teacher facilitates a brief discussion, asking questions to promote critical thinking and deepen students' understanding. For example, the teacher may ask: "Why did you choose this formula for your acid?" or "How did you decide to name your acid according to the naming rules?"

2. Connection to Theory: (3 - 5 minutes)

   • Description: The teacher will then connect the practical activities with the theory, reinforcing the key concepts and acid naming rules. The teacher can do this through a brief review, explaining how the concepts and rules were applied during the activities.

   • Step-by-step:

     1. The teacher begins by recalling the key concepts and acid naming rules.
     2. The teacher then highlights how these concepts and rules were applied during the practical activities. For example, the teacher can say: "Do you remember when you created your own acids? To name them correctly, you had to apply the naming rules we discussed. This shows how the theory we learned is important and useful in practice."
     3. The teacher can also use examples from the activities to reinforce the concepts. For example, the teacher can say: "Look at this acid that Group A created. They used the formula H2SO4 and correctly named it sulfuric acid, according to our nomenclature. This shows us that they understood the theory well and were able to apply it correctly."

3. Final Reflection: (2 - 3 minutes)

   • Description: Finally, the teacher asks students to reflect on what they learned during the lesson. The teacher poses some questions to guide students' reflection and encourage self-assessment.

   • Step-by-step:

     1. The teacher asks students to silently think for a minute about the following questions: "What was the most important concept you learned today?" and "What questions do you still have about acid nomenclature?"
     2. After a minute, the teacher asks some volunteers to share their answers with the class.
     3. The teacher then concludes the lesson, thanking students for their participation and reinforcing the importance of the topic for Inorganic Chemistry and everyday life.

During the Return, the teacher should be an active facilitator, promoting discussion, connecting theory with practice, and encouraging reflection and self-assessment by students. The teacher should also be open to students' questions and doubts, providing additional clarifications if necessary.
