Hello and welcome back to the Curious Kid Podcast.

It's the holiday season and kids all over the world are opening up lots of presents.

Chances are, a lot of those toys you unwrap are going to have something in common.

Tell them about it, Olivia.

A lot of those toys are going to have batteries.

They sure will. I hope you have batteries around because they will probably come in handy this holiday season.

But how do batteries work?

Good question! That's why we're going to talk about batteries this week.

That's a fantastic idea. Many electronics are powered by plugging them into a wall. But that's not always convenient.

Olivia, what are some examples of things that get their power from batteries?

Remote control cars and cell phones. And it's a good thing we can power things using batteries.

Imagine you lose electricity in your house and you aren't

able to see. What would you need? You're going to need a flashlight. Exactly. You would want to

grab a flashlight. If not for batteries, you would need to plug the flashlight into a wall. But remember,

your house doesn't have electricity, so that wouldn't work.

And even if your house did have electricity, some electronics are easier to use when they are battery powered because they are more portable and can be used anywhere you need them.

Can you imagine if batteries didn't exist and we needed to plug flashlights into a wall to use them?

That wouldn't be very convenient at all.

Can you imagine if you had a remote-controlled car, but it had to be plugged into a wall?

It wouldn't go that far at all.

Yeah. As soon as it got too far from the wall, it's plugged into, you wouldn't be able to drive it any further.

That's no fun.
