Imagine sitting down to dinner straight after digging in the mud and stroking the dog, without anyone telling you to wash your hands. For almost all of human history, that was completely normal, because nobody knew there was anything on their hands at all. So what changed?
Wonder Kids will find out how scientists discovered that germs make you sick, what people believed caused illness before then, and why doctors once carried bunches of flowers and herbs. Travel back to London in the summer of 1854 to follow doctor John Snow as he walks the streets of Soho with a map and a mystery to solve. Then meet Louis Pasteur in France and Robert Koch in Germany, two scientists who spent years peering through microscopes.
There are three possible answers to weigh up: one true, one made up, and one that sounds true but isn’t. Can you guess which is which? Listen out for today’s Wonder Words, too.
Wash your hands and pull up a chair, Wonder Kids.
