Hello, everyone! Today, we are going to learn about energy. Let’s first talk about what energy is:

What is Energy?

• Energy is the power that makes things move, work, or grow.

Now, let’s talk about the different forms of energy:

1. Light Energy ☀️

• This is the energy from the sun or a light bulb.
• We use it to see things around us.

2. Heat Energy 🔥

• This is the energy that makes things warm.
• We use it to cook food and keep our homes warm.

3. Sound Energy 🎵

• This is the energy that we hear.
• We use it to listen to music and hear each other talk.

4. Electrical Energy ⚡

• This is the energy that powers our lights, TVs, and other appliances.
• We use it to make things work at home.

5. Mechanical Energy 🛠️

• This is the energy in things that move, like cars or wind-up toys.
• We use it to help us move and play.

Now, let’s talk about how we use energy:

• Light Energy helps us see in the dark.
• Heat Energy keeps us warm and helps us cook our meals.
• Sound Energy lets us hear music and other sounds.
• Electrical Energy powers our homes and schools.
• Mechanical Energy helps us play with toys and use machines.

That’s it for today! Let’s remember to be careful with energy and use it wisely! 😊
