Energy changes happen all around us every day, and it's important to understand how they work. Here are some simple examples:

1. Turning Electricity into Light

• Example: A light bulb takes electrical energy and makes light.
• How It Works: When you turn on the light switch, electricity travels through wires. This makes the bulb hot, and it lights up!

2. Turning Chemical Energy into Heat

• Example: When you burn wood in a fireplace, it turns the energy stored in the wood into heat.
• How It Works: As the wood catches fire, it releases warmth that heats up the room and gives some light.

3. Turning Wind into Electricity

• Example: A wind turbine changes wind energy into electrical energy.
• How It Works: The wind spins the blades of the turbine, which then helps create electricity with internal generators.

4. Changing Potential Energy to Movement

• Example: A roller coaster sitting at the top of a hill has potential energy, which changes to kinetic energy as it goes down.
• How It Works: At the highest point, the potential energy is the greatest, and as it rolls down, kinetic energy, which is energy of movement, increases.

These examples show how energy can change forms. Remember, energy is never lost; it just changes from one kind to another!
