• Examples of electricity-generating materials (e.g., solar panel, turbine)

Building Background / Connection to prior knowledge:

• Recap previous lessons on energy and natural resources.
• Discuss any experiences students may have had with electricity at home or school.

Embedded Core Skills:

• Critical thinking
• Communication
• Observation

Content:

1. Types of electricity (static and current).
2. Methods of generating electricity.

Presentation:

1. Types of electricity:
• Static electricity: Happens when electrons move from one object to another, like when you rub a balloon on your hair and it sticks.
• Current electricity: Flows in a continuous path, like the electricity in wires that powers our homes. âš¡
2. Methods of generating electricity:
• Burning fossil fuels: Using coal, oil, or gas to heat water and produce steam, which turns a turbine to generate electricity.
• Hydroelectric power: Using the force of flowing water to turn turbines and generate electricity. ðŸŒŠ

Class Activity Discussion :

1. What are the two types of electricity?
• Static and current electricity.
2. How is static electricity different from current electricity?
• Static electricity stays in one place, while current electricity flows in a path.
3. What causes static electricity?
• When objects rub against each other and electrons move.
4. Can you give an example of static electricity?
• Rubbing a balloon on your hair and making it stick.
5. What is current electricity used for?
• Powering our homes, schools, and devices.
6. How do we generate electricity?
• By using different methods like burning fossil fuels and harnessing wind and water power.
7. What is hydroelectric power?
• Generating electricity using flowing water, like in dams.
8. What are fossil fuels used for in generating electricity?
• Burning coal, oil, or gas to produce heat and steam, which turns turbines.
9. Can you name a method of generating electricity without burning fossil fuels?
• Wind power, using turbines to convert wind energy into electricity.
10. How does solar power generate electricity?
• Using solar panels to convert sunlight into electricity.
11. What do turbines do in generating electricity?
• They spin to generate electricity from different energy sources.
12. Why is electricity important?
• It powers our lights, appliances, and gadgets, making our lives easier.
13. What happens when we turn on a switch?
• It allows electricity to flow through wires and power devices.
14. How does electricity reach our homes?
• Through power lines connected to substations and transformers.
15. Why should we conserve electricity?
• To save energy and protect the environment for future generations.
