Hello and welcome to a brand new episode of the Fun Kids Science Midweekly. It's you, it's me,

my name's Dan, and it's a whole bunch of brilliant questions about science through the solar system and beyond.

Let's get to it then. If you ever have anything sciencey that you

want answered on this show, make sure you leave it as a voice state for me on funkidslife.com. You can do

it on the FunKids app too. And that way you can star in the podcast. We'll go on an adventure

together. We'll explore so much. I can't wait to do the digging all about your question.

All right?

So simple.

Free Fun Kids app, you can do it at funkidslive.com too.

And energy creates heat. Movement makes energy, which makes heat. So, the muscles all

over your body, they twitch, they spasm, which is why you shiver. You're shivering to try and warm up

your body temperature. It moves your muscles to warm up your tissues, which lifts that temperature.

It makes you warmer. And your teeth also chatter because of that shivering. So that's why you shiver when you're cold. It's to try and kind of move. So you get hot. Sometimes you shiver when you're creeped out, though, don't you? Something strange has happened. And you get, ooh, the tingling shiver up your spine.
