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. ⚡
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. 🌊

   • 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.
