Right, welcome along. It's the Fun Kids Science Weekly, the only place where your minds need to be ready for moulding.

Yeah, my name's Dan. Thanks for giving us a listen. This week we learn exactly why the food that you put into your body is so important to how you live and also how you can raise some cash for really important causes just by thinking more about that and maybe giving up some of your favourite foods for the next few months.

Back in a jiffy!

Helly-tellibble, ready to launch in three, two, one.

He's got quite a fever.

Welcome to the immune system in action.

Microbes like being at the body's normal temperature, 37 degrees Celsius.

They don't like it when the body raises the temperature to help fight off infections.
