Introduction (10 - 15 minutes)

1. Review of previous contents: The teacher starts the lesson by recalling the concepts of kinematics, especially those of bidimensional and unidimensional motion, which are fundamental for understanding oblique motion. Additionally, the teacher may briefly review the concepts of initial velocity, acceleration, and forces, which will be applied in a more complex way in the current lesson. (3 - 5 minutes)

2. Problem situations: The teacher presents two problem situations involving oblique motions. One could be the description of a projectile launch in a soccer game, and the other could be the trajectory of an object thrown in an amusement park. The teacher asks students to think about how they could solve these problems and to write down their ideas. (2 - 3 minutes)

3. Contextualization: The teacher explains that the kinematics of oblique motions is essential to understand various natural phenomena and technological applications. For example, understanding the motion of a launched object is essential for rocket and satellite engineering. Additionally, the kinematics of oblique motions is widely applied in sports, such as soccer, basketball, and baseball, to predict the trajectories of balls and improve players' performance. (2 - 3 minutes)

4. Introduction to the topic: The teacher introduces the topic of the lesson, kinematics of oblique motions, and emphasizes the importance of this subject. They may mention that projectile motion is one of the first problems Isaac Newton attempted to solve, leading to the development of modern physics. Furthermore, the teacher may mention that the kinematics of oblique motions is one of the most challenging topics in high school physics, but with proper understanding of the concepts and sufficient practice, students will be able to master it. (3 - 4 minutes)

Development (20 - 25 minutes)

1. Laboratory Activity: Projectile Launch (10 - 12 minutes)

   • The teacher organizes students into groups of up to five members and distributes the necessary materials: tennis balls, balloons, adhesive tape, ruler, and stopwatches.
   • Each group must build their own projectile launcher, which consists of stretching a balloon at the end of a ruler and securing it with adhesive tape. The balloon will be inflated and released to launch the 'tennis ball projectile'.
   • The teacher instructs the groups to vary the launcher's inclination (launch angle) and the force with which they inflate the balloon (initial velocity), and to measure the distance traveled by the tennis ball (the projectile's trajectory).
   • Each group should record the data obtained and then try to determine the necessary initial velocity and launch angle to reach a certain distance.
   • After the conclusion of the activity, the teacher leads a classroom discussion about the results, relating them to the concepts of kinematics of oblique motions.

2. Practical Activity: Problem Solving (10 - 12 minutes)

   • The teacher distributes a list of oblique motion kinematics problems to each group.
   • The problems can vary in difficulty and complexity, and may include determining the initial velocity, launch angle, maximum height, horizontal range, among others.
   • Each group must work together to solve the problems, using the formulas and concepts learned.
   • The teacher circulates around the room, assisting groups that encounter difficulties and encouraging discussion and critical thinking.
   • After the conclusion of the activity, the teacher selects some problems to be solved together with the class, reinforcing the concepts and clarifying possible doubts.

3. Discussion Activity: Applications of Oblique Motion (3 - 5 minutes)

   • The teacher proposes a classroom discussion about the practical applications of oblique motion, reinforcing the importance of this concept in the real world.
   • The teacher may mention examples of applications in sports, engineering, physics, among others, and ask students to think of other examples.
   • Students are encouraged to share their ideas and explain how oblique motion is applied in each case.
   • The teacher concludes the activity by highlighting the relevance of the topic studied and reinforcing the concepts learned.

Return (10 - 12 minutes)

1. Group Discussion (5 - 7 minutes)

   • The teacher gathers all students and asks each group to share their solutions or conclusions from the practical activities and problem-solving.
   • Each group has a maximum of 3 minutes to present, ensuring that all students have the opportunity to share their ideas.
   • During the presentations, the teacher should encourage active participation from all students, asking questions to stimulate reflection and critical thinking.
   • The teacher should also take this opportunity to clarify doubts and correct possible misunderstandings, reinforcing the correct concepts and the proper way to apply them.

2. Connection with Theory (2 - 3 minutes)

   • After the group presentations, the teacher briefly reviews the theoretical concepts discussed at the beginning of the lesson, relating them to the solutions and conclusions presented by the students.
   • The teacher highlights how the practice and application of theoretical concepts help solidify understanding, and how theory provides the necessary tools to solve practical problems.
   • The teacher also takes this opportunity to reinforce the importance of approaching physics not only as a theoretical discipline, but as a science that allows us to understand and explain real-world phenomena.

3. Individual Reflection (2 - 3 minutes)

   • To conclude the lesson, the teacher proposes that students reflect for a minute on the following questions:
     1. What was the most important concept I learned today?
     2. What questions have not been answered yet?
   • After a minute of reflection, the teacher invites students to share their answers.
   • This final step is crucial for students to consolidate what they have learned, identify possible gaps in their understanding, and prepare for the next lesson.

4. Feedback and Closure (1 minute)

   • The teacher thanks everyone for their participation, encourages students to continue studying the subject, and informs that they will be available to clarify any doubts that may arise.
   • The teacher asks students to provide feedback on the lesson, inquiring if they believe their objectives were achieved and if they feel confident in solving oblique motion problems.
   • Based on the students' feedback, the teacher can adjust the approach and activities for the upcoming lessons, aiming to maximize learning and student engagement.
