📚 Part 1: Energy Types and Definitions

Energy is the ability to do work or cause change. Energy can change from one type to another - this is called energy transformation.

Common Types of Energy:

Chemical energy - stored in food, batteries, and fuel

Kinetic energy - energy of movement

Heat energy - energy that makes things warm

Light energy - energy we can see

Sound energy - energy we can hear

Electrical energy - energy that flows through wires

1. What is energy transformation?

When energy disappears

When energy changes from one type to another

When energy gets bigger

2. Which type of energy is stored in a battery?

Sound energy

Chemical energy

Light energy

3. A moving car has which type of energy?

Kinetic energy

Chemical energy

Sound energy

🔄 Part 2: Energy Transformations in Action

4. When you turn on a torch, what energy transformation happens?

Chemical energy (in battery) → _____________ energy → _____________ energy

5. Match each device with its main energy transformation:
A. Microwave oven
B. Car engine
C. Solar panel
D. Speaker
1. Chemical → Kinetic + Heat
2. Light → Electrical
3. Electrical → Heat
4. Electrical → Sound
6. Fill in the blanks for these energy transformations:

a) Eating food: Chemical energy → _____________ energy (for your body)

b) Wind turbine: Kinetic energy → _____________ energy

c) Campfire: Chemical energy → _____________ energy + _____________ energy

✏️ Part 3: Everyday Examples

7. Choose TWO types of energy that a television uses and produces:

Electrical energy (input)

Chemical energy

Light energy (output)

Sound energy (output)

8. Describe one energy transformation you can see in your classroom right now:
9. Draw and label a simple energy transformation (e.g., a person kicking a ball):
