Objectives (5 - 7 minutes)

1. Understand the Concept of Energy and its Forms: Students will be able to define energy, identify its different forms (such as mechanical, thermal, light, sound, electrical, and chemical), and understand how it can be transformed from one form to another.

2. Learn about Energy Transmission: Students will explore how energy is transmitted from one object to another, focusing on the concepts of energy transfer and energy flow.

3. Explore Real-Life Applications: Students will apply their understanding of energy and its transmission to real-world scenarios, identifying examples of energy transformation and transmission in everyday life.

Secondary Objectives:

• Enhance Collaborative Learning Skills: By engaging in a flipped classroom methodology, students will develop their collaborative learning and problem-solving skills.

• Encourage Self-Directed Learning: The flipped classroom approach will also promote independent and self-directed learning, as students will be required to study the lesson materials at home before coming to class.

Introduction (10 - 12 minutes)

1. Review of Previous Knowledge: The teacher begins by reminding students of the basic concepts of energy they have learned in previous classes, such as the definition of energy and the different forms of energy. The teacher asks a few quick questions to assess the students' recall, such as "Can anyone give an example of mechanical energy?" and "What is the energy transformation that occurs when you turn on a light bulb?" This review helps to set the stage for the new concepts to be learned. (3 - 4 minutes)

2. Problem Situations: The teacher presents two problem situations to the students. The first situation involves a battery-operated toy car that stops moving after a while. The second situation involves a hot cup of coffee that cools down over time. The teacher asks the students to think about why these situations occur and what might be happening with the energy involved. This stimulates the students' curiosity and gets them thinking about the concept of energy and how it changes. (3 - 4 minutes)

3. Real-World Context: The teacher explains the importance of understanding energy and its transmission in our daily lives. They discuss how energy is used in our homes, in transportation, in industries, and in the natural world. The teacher highlights how this knowledge can help us make more efficient use of energy, leading to savings in cost and resources. They also point out that many of the technological advancements we enjoy today, like electricity and vehicles, are possible because of our understanding of energy. (2 - 3 minutes)

4. Engaging Introduction of the Topic: To grab the students' attention, the teacher shares two interesting facts related to the topic. The first fact is about the sun, which is the primary source of energy for our planet. The teacher explains that the sun's energy travels to Earth in the form of light and heat. The second fact is about a popular game that most students are familiar with, like a bouncing ball. The teacher explains that when a ball bounces, the energy is transformed from potential energy (when the ball is still) to kinetic energy (when the ball is in motion). These facts aim to spark the students' interest and curiosity about the topic. (2 - 3 minutes)

Development

Pre-Class Activities (10 - 15 minutes)

1. Reading Assignment: Students are assigned a short reading passage at home that introduces them to the concept of energy and its forms. The passage includes examples of different types of energy and how they can be transformed from one form to another.

2. Video Watching: Students are given the link to an engaging, animated video that visually explains the concept of energy and its transmission. The video uses examples from everyday life and nature to help students understand the concept better.

3. Quiz: After the reading and video-watching, students take a quick online quiz to test their understanding of the concepts. The quiz includes multiple-choice and true/false questions that cover the basics of energy and its forms, as well as energy transmission.

In-Class Activities (20 - 25 minutes)

Activity 1: Energy Transformations and Transmission Card Game

1. Objective: This activity aims to reinforce the students' understanding of energy and its transmission by having them match energy types with examples of energy transmission.

2. Materials: Cards with different energy forms (thermal, light, sound, electrical, and chemical) and cards with examples of energy transmissions (a light bulb, a car engine, a fire, a wind turbine, a running person, etc.).

3. Procedure:

   • The teacher divides the students into small groups of 4 or 5 and distributes the energy and transmission cards to each group.
   • The students have to match the energy type cards with the examples of energy transmission cards. For example, the card with "heat from a fire" should be matched with the "thermal energy" card.
   • Once all the cards have been matched, the groups present their matches to the class, explaining the energy transformations and transmissions they have identified.
   • The teacher provides feedback and corrections as necessary, ensuring each group has a clear understanding of the activity's concepts.

Activity 2: Designing an Energy Efficient Device

1. Objective: This hands-on activity challenges students to apply their understanding of energy and its transmission in a practical, real-world context. By designing an energy efficient device, students will explore how energy can be transformed and transmitted in an efficient manner.

2. Materials: Assorted craft supplies (cardboard, tape, straws, rubber bands, etc.), small LED lights, and small battery packs.

3. Procedure:

   • The teacher explains the task: "Your group's mission is to design a simple device that can use energy (from the battery) and transform it into a useful form (light from the LED) as efficiently as possible."
   • Groups are given time to brainstorm and design their device. They should consider how different forms of energy and their transmission can be utilized in their design.
   • Once the devices are completed, each group presents their design to the class. They explain the energy transformations and transmissions happening in their device and how their design promotes energy efficiency.
   • The teacher encourages the students to ask questions and provide feedback on each group's design, fostering a collaborative learning environment.

By engaging in these hands-on, collaborative activities, students will not only deepen their understanding of energy and its transmission but also develop important skills such as teamwork, problem-solving, and communication.

Feedback (8 - 10 minutes)

1. Group Discussions: The teacher facilitates a group discussion where each group gets a chance to present their solutions or conclusions from the activities. Each presentation should not exceed more than 3 minutes. The teacher encourages other students to ask questions and provide constructive feedback. This activity promotes a collaborative learning environment and allows students to learn from each other's perspectives. (3 - 4 minutes)

2. Connection of Activities with Theory: After all groups have presented, the teacher discusses how the activities connect with the theoretical concepts of energy and its transmission. They highlight the key learning points from the activities and explain how these points relate to the real-world applications of energy and its transmission. For example, the teacher might point out that the card game activity demonstrated how different types of energy can be transformed and transmitted in various devices, while the device design activity showed how understanding these energy transformations and transmissions can help us create more efficient devices. (2 - 3 minutes)

3. Reflection Time: The teacher asks the students to take a moment to reflect on what they have learned in the lesson. They might ask the following questions:

   • "What was the most important concept you learned today?"
   • "Can you think of any real-world examples where energy transformation and transmission are important?"
   • "What questions do you still have about energy and its transmission?" The teacher encourages the students to share their reflections, promoting a deeper understanding and awareness of their learning. (2 - 3 minutes)

4. Wrap Up: To conclude the feedback session, the teacher summarizes the main points of the lesson, reiterates the importance of understanding energy and its transmission, and addresses any common questions or misconceptions that arose during the activities or group discussions.
