2. Problem situations:

   • The instructor poses two problem situations to trigger the students' thinking. The first one is about a bicycle being pedaled and a light turns on as a result. What happened to the energy that was in the cyclist's muscles? How was this energy transformed into electrical energy to turn on the light? The second situation is about an incandescent light bulb that heats up its environment when it is switched on. What happened to the electrical energy that entered the bulb? How was this energy transformed into heat? (5-7 minutes)

3. Contextualization of the topic's importance:

   • The instructor explains that understanding energy transformation is crucial for the functioning of countless devices and systems that we use in our everyday lives, such as cars, computers, cell phones, etc. Furthermore, the ability to identify and understand how energy is transformed is fundamental to comprehending natural phenomena and for devising more sustainable energy solutions. (2-3 minutes)

4. Gaining students' attention:

   • The instructor shares two fun facts about energy transformation. The first one is about how solar energy is transformed into electrical energy in solar panels. The second one is about how wind energy is transformed into electrical energy in wind turbines. Both examples relate directly to energy transformation and the importance of renewable energies. (3-5 minutes)

Development (20-25 minutes)

1. Simulation Activity - "Transforming Energy" (10-12 minutes)

   • The instructor divides the class into groups of 4-5 students and provides each group with a box containing different materials such as pencils, rubber bands, toy cars, batteries, light bulbs, etc.

   • Each group is tasked to create a device that demonstrates the transformation of one form of energy into another. For example, they could create a toy car that, when pushed forward (mechanical energy), turns on a light (electrical energy), or a pulley system that, when pulled, makes a pencil spin (mechanical energy to kinetic energy).

   • During the activity, the instructor circulates around the room, observing the groups' work, helping to solve problems and encouraging discussion about the energy transformations that are taking place.

   • After the completion of the activity, each group is invited to present their device to the class, explaining the energy transformations that are occurring. The rest of the class should ask questions and provide feedback on the presentations.

2. Practical Activity - "Energy Transformation in Everyday Life" (10-12 minutes)

   • Still in groups, the students are instructed to observe the classroom environment and identify at least three examples of energy transformation that are happening there. It could be the electrical energy that powers the lights, the heat generated by the projector, the kinetic energy of students moving around, among others.

   • Each group should record their examples and explain the energy transformations involved. They may use drawings, diagrams, or write down their explanations.

   • After the completion of the activity, each group shares their observations and explanations with the class.

   • The instructor then leads a classroom discussion, connecting the students' observations to the concept of energy transformation. The goal is for students to realize that energy transformations are not limited to laboratory situations but are present in our daily lives, all the time.

3. Discussion Activity - "Energy Transformation and Sustainability" (5-7 minutes)

   • The instructor leads a classroom discussion about the importance of energy transformation for sustainability.

   • Students are encouraged to think of examples of how energy transformation can contribute to or hinder sustainability. For instance, the transformation of energy from the sun into electricity in solar panels is a sustainable form of energy generation, whereas the transformation of energy from fossil fuels into electricity in power plants contributes to air pollution and global warming.

   • The instructor guides the discussion, asking probing questions and encouraging all students to participate. The goal is for the students to develop a deeper understanding of the importance of energy transformation for sustainability and to become more aware of their own energy choices.

Debrief (8-10 minutes)

1. Group Discussion (3-4 minutes)

   • The instructor facilitates a group discussion with the entire class, where each group gets the opportunity to share the solutions or conclusions they reached during the activities.
   • Each group has a 3-minute time limit to present their main observations and conclusions. During the presentations, other students are encouraged to ask questions and provide constructive feedback.
   • This is an important time for students to learn from each other and for the instructor to assess the students' comprehension and application of the energy transformation concepts.

2. Connection to Theory (2-3 minutes)

   • Following the group presentations, the instructor briefly summarizes the main conclusions, reinforcing the connection between the hands-on activities and the theory of energy transformation.
   • The instructor may highlight interesting or successful examples of energy transformation presented by the groups, emphasizing the concept's applicability in real-life situations.
   • This is also a time to clarify any misunderstandings or misconceptions that may have arisen during the activities.

3. Individual Reflection (2-3 minutes)

   • The instructor asks the students to reflect individually on what they learned during the lesson. They should think about answers to the following questions:
     1. What was the most important concept you learned today?
     2. What questions do you still have?
   • Students can write their responses in a notebook or on a piece of paper.
   • This reflection helps students to consolidate what they have learned and to identify any areas that they have yet to fully grasp. It also provides the instructor with valuable feedback on the effectiveness of the lesson and which concepts may need further review or practice.

4. Feedback and Closure (1 minute)

   • Finally, the instructor thanks everyone for their participation and reinforces the importance of understanding energy transformation for everyday life and for sustainability.
   • The instructor may also use this time to address any questions that were not answered yet and to provide general feedback on the class performance.
   • Students are encouraged to review the content at home and to bring any doubts or questions to the next class.
