Lesson Content

Energy Conversion: Electrical and Chemical Energy to Heat Energy

Energy conversion is the process where energy changes from one form to another to perform useful tasks.

1. Electrical Energy to Heat Energy:
   • When electrical energy passes through a device like a bulb, it produces heat.
   • Examples include electric irons, heaters, and stoves.
2. Chemical Energy to Heat Energy:
   • Burning fuels like candles or gas produces heat energy.
   • Examples include burning wood for cooking or lighting candles.

Lesson Evaluation

To evaluate the learning, the teacher asks pupils to:

1. Define energy conversion.
2. Explain how electrical energy converts to heat energy.
3. Provide two examples of chemical energy converting to heat energy.
4. Demonstrate energy conversion using any available material in class.
5. State two uses of heat energy in homes.
