     • The first situation could be a leak in a pipeline in a house. The teacher can ask: 'How can we measure the amount of water leaking per minute?'
     • The second situation could be a water fountain in a park. The teacher can ask: 'How can we calculate the amount of water the fountain 'throws' up every second?'

3. Contextualization:

   • The teacher should explain the importance of studying flow rate, highlighting its practical applications in various areas such as engineering, architecture, agriculture, among others.
   • In addition, the teacher can mention real examples of how flow rate is used, such as measuring a house's water consumption, sizing irrigation systems, predicting floods, among others.

4. Introduction to the topic:

   • The teacher can start the Introduction to the topic by telling a brief story about the origin of the study of hydrodynamics and the importance of the concept of flow rate.
   • In addition, the teacher can present curiosities related to the topic, such as the fact that the concept of flow rate has been used since ancient times, when the Romans built aqueducts to transport water from one region to another.

This stage of the class is crucial to arouse students' interest in the topic, contextualizing it and showing its relevance. In addition, the review of previous contents helps reinforce the necessary concepts for understanding the new topic.

Development (20 - 25 minutes)

1. Practical activity: 'Measuring Flow Rate' (10 - 12 minutes)

   • The teacher should divide the class into groups of up to 5 students and provide each group with the following materials: a 1-liter bucket, a garden hose, and a stopwatch.
   • The teacher should explain that the groups' task will be to measure the water flow rate of the hose using the provided materials. For this, students should fill the bucket with water from the hose and measure the time required to fill it completely. They should repeat the procedure three times and calculate the average of the times obtained.
   • After the activity, students should record the results, and the teacher should guide them to calculate the average flow rate of the hose using the formula Flow Rate = Volume / Time.

2. Problem-solving activity: 'Flow Rate Problems' (10 - 12 minutes)

   • The teacher should provide each group with a sheet of flow rate problems to be solved. The problems should vary in difficulty and application contexts, so that students can practice applying the formula in different situations.
   • Students should work together to solve the problems, using the flow rate formula and the problem-solving skills they developed in the previous activity.
   • The teacher should circulate around the room, assisting groups that are having difficulties and ensuring that all students are involved in the activity.

3. Discussion and feedback: (5 - 7 minutes)

   • After the activities, the teacher should promote a classroom discussion, asking students to share their answers and problem-solving strategies.
   • The teacher should take this opportunity to clarify any doubts that may have arisen during the activities and reinforce the important concepts related to flow rate.
   • In addition, the teacher should provide feedback to the students, praising their efforts and highlighting the strengths of their answers, as well as pointing out areas for improvement.

This stage of the lesson plan focuses on the practice and application of the flow rate concept. The proposed activities allow students to experience and investigate the concept of flow rate in a practical way, strengthening their understanding and problem-solving skills. In addition, the discussion and feedback help consolidate learning and clarify any doubts that may have arisen.

Return (8 - 10 minutes)

1. Group discussion (3 - 4 minutes):

   • The teacher should gather all students and promote a group discussion about the solutions or conclusions found by each team.
   • During the discussion, the teacher should highlight the different approaches used by the groups to solve the problems or make the measurements.
   • In addition, the teacher should reinforce the key concepts related to flow rate, showing how they were applied in each situation.

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

   • After the group discussion, the teacher should make the connection between the practical activities carried out and the theory presented at the beginning of the class.
   • The teacher should explain how the flow rate formula, which was used by students to solve the problems, is directly related to the concepts of volume and time, which were reviewed in the Introduction of the class.
   • In addition, the teacher can refer to the real-world examples discussed in the contextualization, showing how the understanding of flow rate can be applied in real situations.

3. Individual reflection (2 - 3 minutes):

   • To conclude the class, the teacher should propose that students reflect individually on what they have learned.
   • The teacher can ask questions like: 'What was the most important concept you learned today?' and 'What questions have not been answered yet?'.
   • Students should have a minute to think about the answers to these questions.
   • After the reflection, students can be invited to share their answers with the class, if they wish.

4. Teacher's feedback (1 minute):

   • The teacher should provide brief feedback on the class, highlighting the strengths of student engagement, the questions that were well answered, and areas that may need more practice or review.
   • In addition, the teacher should reinforce the importance of the flow rate concept and encourage students to continue exploring the topic outside the classroom.

This stage of the lesson plan is crucial to consolidate learning and promote reflection on what has been learned. Group discussion and connection with theory help solidify concepts in students' minds, while individual reflection allows them to assess their own understanding and identify any areas of confusion or doubt.

Conclusion (5 - 7 minutes)

1. Summary and Recapitulation (2 - 3 minutes):

   • The teacher should start the Conclusion by summarizing the main points covered during the class. This may include the definition of flow rate, the formula for calculating flow rate, and how to apply this concept in real problems.
   • The teacher can quickly review the practical examples and problems that were discussed, reinforcing the fundamental concepts and clarifying any remaining doubts.

2. Connection between theory and practice (1 - 2 minutes):

   • Next, the teacher should highlight how the class managed to connect theory with practice. This can be done by recalling the practical activities carried out, such as measuring the hose's flow rate, and how they reflect the theoretical concepts discussed.
   • The teacher can also reinforce how the flow rate formula, which was used to solve the problems, is a direct application of the concepts of volume and time, which were reviewed in the Introduction of the class.

3. Extra materials (1 minute):

   • The teacher should then suggest extra materials for students who wish to deepen their knowledge on the subject. This may include physics books, educational websites, explanatory videos, and extra exercises.
   • For example, the teacher may suggest reading a specific chapter of a physics book that explains in more detail the concept of flow rate, or a YouTube video that demonstrates how to calculate flow rate in different situations.

4. Importance of the subject (1 - 2 minutes):

   • Finally, the teacher should emphasize the importance of studying flow rate. This can be done by recalling the practical applications discussed in the contextualization, and how understanding this concept can be useful in various everyday situations, from measuring water consumption in a house to sizing irrigation systems.

This stage of the lesson plan is essential to consolidate learning and reinforce the importance of the subject. By summarizing the main points, connecting theory with practice, suggesting extra materials, and highlighting the relevance of the subject, the teacher helps solidify the knowledge acquired by students and motivates them to continue exploring the topic.
