Really True! - Science Podcast for Kids

Wow! Do we really only use 10% of our brain?

Is the ten-percent-brain thing actually true? Almost every grown-up has heard this myth - and almost everyone believes it. Today Robin and Lou clear up one of the biggest science fairy-tales of our time. In the brain scanner you can see it plainly: we use our brain all the time - while talking, walking, dreaming, breathing, remembering, even while doing nothing. The myth comes from old popular-science books and was boosted by Hollywood movies like „Lucy„. But researchers with modern MRI machines show it clearly: over the course of a day every brain region is active, each with its own special job. This episode is a perfect example of how science communication can dissolve a myth. Kids learn that just because a claim is repeated often doesn't make it true. And they discover how their own brain pulls off amazing feats every single day. What you'll hear in this episode: Why the 10% myth is so stubborn How the brain scanner (MRI) shows what's happening in your head What the different brain regions do - language, movement, memory Why your brain uses 20 percent of your whole body's energy What Hollywood movies like „Lucy„ have to do with spreading the myth Why sleep, exercise and reading strengthen your brain How kids' brains grow and build new connections What researchers know today about learning and memory Who is this episode for? For curious kids aged 6 and up who want to know how their own head works. For parents who want to talk with their child about myths, the brain and the media.
