For example, "Can anyone give me an example of a type of energy we learned about last class?" or "Why is energy important in our daily lives?" (2 minutes)

• The teacher will then present two problem situations to the students that will serve as a basis for the development of the theory. These could be:

  1. "Imagine you live in a remote village with no access to electricity. How would you light up your house at night without using batteries or fuel-powered generators?"
  2. "Consider a city that relies heavily on coal for electricity. What possible environmental issues could this city face?" (3 minutes)

• The teacher will contextualize the importance of the subject by discussing real-world applications and current events. They may talk about how the use of renewable energy sources can help to mitigate climate change and reduce air pollution. They can also mention recent news about countries or cities that have successfully transitioned to renewable energy. (2 minutes)

• The teacher will then introduce the topic of natural sources of energy in a captivating way. They can share interesting facts such as:

  1. "Did you know that the energy in sunlight that hits the Earth in just one hour could meet all our energy needs for a whole year if we could harness it all?"
  2. "Or that wind power is the fastest-growing source of electricity production in the world, with many countries now getting a significant percentage of their power from wind turbines?" (3 minutes)

• The teacher will conclude the introduction by stating the objectives of the lesson and how it will help the students understand the importance of harnessing energy from natural sources. They will also remind the students that they will be learning some of the concepts at home through a flipped classroom approach. (2 minutes)

Development

Pre-Class Activities (10 - 12 minutes)

• The students are provided with a set of online resources such as videos, articles, and interactive quizzes. They are to use these resources to understand the different natural sources of energy and the process involved in harnessing them. They should also note down any questions or doubts they have about the topic. (5 - 7 minutes)

• The students are then assigned a task to create a small presentation on one particular natural source of energy and its benefits. They can use digital tools like PowerPoint, Google Slides, or Canva for their presentations. This will help them actively engage with the topic and develop their research and presentation skills. (5 - 7 minutes)

In-Class Activities (20 - 25 minutes)

• Activity 1: Energy Expo (10 - 12 minutes)

  1. The class is divided into groups, with each group representing a specific natural source of energy: sunlight, wind, water, or geothermal energy.
  2. The groups are given craft supplies (colored papers, markers, glue, etc.) and asked to create a poster that includes information about their energy source, its process of generation, and its environmental benefits. They should also be prepared to explain their energy source to the rest of the class.
  3. Once the posters are completed, the teacher will organize an "Energy Expo" where each group presents their poster and explains their energy source to the rest of the class. This activity will not only reinforce their understanding of the topic but also enhance their presentation and communication skills.

• Activity 2: Energy Debate (10 - 13 minutes)

  1. After the "Energy Expo," the teacher will introduce a debate on the topic: "Which is the best natural source of energy: sunlight, wind, water, or geothermal energy?"
  2. The class is divided into two groups - one group argues in favor of sunlight and wind energy, while the other group argues for water and geothermal energy.
  3. Each student has a chance to put forth their argument, and the debate is conducted in a structured format, with a moderator and a timekeeper.
  4. The aim of this activity is to encourage critical thinking, research skills, and public speaking skills. The students will also learn to appreciate the benefits and limitations of different natural sources of energy.

By the end of the in-class activities, students should have a clear understanding of the different natural sources of energy, how they are harnessed, and their environmental benefits. They should also have developed their research, presentation, critical thinking, and public speaking skills.

Feedback (5 - 7 minutes)

• The teacher will begin the feedback session by asking each group to share their conclusions from the energy debate. The teacher will then facilitate a brief discussion on the strengths and weaknesses of each natural source of energy, focusing on their environmental impact and sustainability. This will help students understand the complexity of the energy mix and the importance of diversifying our sources of energy. (3 minutes)

• The teacher will then connect the in-class activities with the theory, revisiting the key concepts about natural sources of energy, their generation process, and their environmental benefits. They will also address any misconceptions that may have arisen during the activities. For example, if a group argued that sunlight was the best natural source of energy because it is the most abundant, the teacher can explain that while this is true, each source of energy has its own unique advantages and limitations. (2 minutes)

• The teacher will ask students to reflect on what they have learned in this lesson. They will pose questions such as:

  1. "What was the most important concept you learned today?"
  2. "Which natural source of energy do you think is the most promising for the future? Why?"
  3. "How do you think we can encourage the use of more renewable energy sources in our community?"
  4. "What questions do you still have about natural sources of energy?" (2 minutes)

• The teacher will then collect the group posters and presentations for assessment. They will provide feedback on the students' understanding of the topic, their ability to collaborate and communicate effectively, and their creativity in presenting the information. The teacher will also use this opportunity to address any common misconceptions and to reinforce the key learning points of the lesson. (2 minutes)
