Initial Activity

Thought-Provoking Question: "How would our daily lives be affected if we had no access to electricity?" Short Video: Present a 3-minute video illustrating various forms of energy generation and their environmental implications. (Suggestion: YouTube video on 'Types of Energy Generation.').

Development

Duration: 55 - 60 minutes

The objective of this stage is to reinforce the students' understanding of the various forms of energy generation through practical and reflective activities. This will enable students to apply what they've learned in a creative and collaborative manner while developing the critical and analytical skills necessary for understanding the economic, environmental, and social implications of different energy sources.

Topics

1. Fossil Fuel

2. Nuclear

3. Wind

4. Solar

Thoughts on the Subject

Motivate students to think about the necessity of diversifying energy sources. Discuss how dependency on a single energy source can affect society both positively and negatively. Encourage them to examine the economic, environmental, and social dimensions of this reliance.

Mini Challenge

Building a Wind Turbine Model

Students will create a simple model of a wind turbine using recyclable materials and small electric motors. This hands-on activity will help them grasp how wind turbines work and how kinetic energy is transformed into electrical energy.

1. Split students into groups of 4 to 5.

2. Provide the necessary materials: plastic bottles, skewers, small electric motors, cardboard or plastic blades, tape, and scissors.

3. Guide each group to follow the steps to construct the wind turbine:

4. Cut the plastic bottle in half to form the base of the turbine.

5. Make openings in the base for the skewers serving as an axis for the blades.

6. Fasten cardboard or plastic blades onto the skewers.

7. Attach the electric motor to the blades' axis using tape.

8. Assemble the structure so that the blades can rotate freely when air is blown.

9. Test the turbine by blowing air or using a fan to generate wind, and observe electrical energy production.

10. Encourage groups to share any challenges encountered during construction and how they overcame them.

11. Prompt each group to present their model, explaining its construction process and functionality.

Demonstrate how wind's kinetic energy can be converted into electrical energy practically, while fostering creativity and teamwork.

**Duration: 35 - 40 minutes

Evaluation Exercises

1. List the primary forms of energy generation and outline one advantage and disadvantage for each.

2. Explain the process by which a fossil fuel power plant generates electricity.

3. Discuss the positive and negative environmental effects of nuclear power plants.

4. Conduct a quick research project on a wind or solar power plant in India and describe its key features.
