Hey there, curious minds! Welcome to Fizz Pop Wow, the super fun science podcast where we answer big questions with quick, exciting answers in less than five minutes. I'm Michelle, and today's question is full of energy. How does a battery power things? Let's find out!
The Science of Batteries
Have you ever pressed a button on a toy, a flashlight, or a remote control, and—ta-da!—it turns on? That’s because of a tiny but mighty power source—a battery! But how does a small battery make things light up, move, or play sounds? It’s not magic—it’s science! A battery is like a tiny energy factory. Inside, different chemicals work together to create electricity.
What’s Inside a Battery?
Most batteries have three main parts:
When you put a battery into a toy or flashlight, you complete a circuit—a path for electricity to travel. Inside the battery, a tiny chemical reaction starts, and electrons (super tiny particles) move from the negative side to the positive side, traveling through wires and making things work.

Materials Needed:
- A flashlight
- Batteries
Steps to Follow:
- Find a flashlight and take the batteries out.
- Now try putting them back in, but flip one upside down.
- What happens? The flashlight won’t work!
- That’s because electricity needs to flow in a loop, and if the batteries are not in the right order, the circuit is broken!
Your Challenge
Take a look around your house. How many things use batteries? Are they big or small, rechargeable or one-time use? Keep an eye out for where batteries bring things to life!
