Scientist Nina and her young experimenters investigate the human body and find out why it is brilliant. Nina investigates how people remember so many things, with the help of her five sense neurons. Experimenters Lewis, Mason and Sam visit Nina in her lab and find out that the senses are really important in remembering things. They discover that smelling, tasting, seeing, hearing or touching something can spark a memory. So tasting some popcorn can remind them of going to the cinema. A second experiment shows them that the more senses someone uses to examine something, the stronger the memory of it gets, helping them to remember it later. Finally they go to a beach and make paths in the sand. They see that once a path is made, it's easy to follow it again. And the more they follow it, the deeper and clearer the path gets. Nina explains that this is like memory. Each memory is like a path in the brain and the more often you remember something, the easier it is to remember it again.
