Energy: Types of energy (light, heat, sound), energy conversion

Types of Energy
1. Light Energy: Energy from the sun or artificial sources that enables us to see.
2. Heat Energy: Energy that warms or cools objects, often transferred through conduction, convection, or radiation.
3. Sound Energy: Energy that produces sound waves, enabling us to hear.

Energy Conversion
1. Conversion of Light Energy:
    1. Solar panels convert light energy into electrical energy.
    2. Eyes convert light energy into signals sent to the brain.
2. Conversion of Heat Energy:
    1. Thermal power plants convert heat energy into electrical energy.
    2. Refrigerators convert electrical energy into heat energy (for cooling).
3. Conversion of Sound Energy:
    1. Microphones convert sound energy into electrical energy.
    2. Speakers convert electrical energy into sound energy.

Examples and Applications
1. Light Energy: Solar-powered homes, flashlights, and lasers.
2. Heat Energy: Heating systems, geothermal power plants, and fireplaces.
3. Sound Energy: Music instruments, public address systems, and hearing aids.

Fun Activities
1. Energy Conversion Diagrams: Draw diagrams illustrating energy conversions.
2. Energy Scavenger Hunt: Find examples of different energy types and conversions in daily life.
3. Homemade Solar Oven: Build a simple solar oven to demonstrate light energy conversion.
