It's a Halloween special as Forensic Anthropologist and now secondary school science teacher Miss Robinson gives Greg and Bella a lesson about how to grow a human skeleton.

Miss Robinson will welcome Greg and Bella into her Forensics lab, to show them a host of props and remains to see what they can teach us about our bones. Along the way, they'll find out what your bones are made of, how they are formed, what happens if you break one, and how possible it is to grow them back if something happens to one of them. And Bella asks, can we grow a skeleton in a lab?

There will be lots of amazing facts, some grizzly stories and plenty of laughs along the way as Greg and Bella share their stories of broken bones and marvel at just how long it takes to grow a full skeleton. At the end of the episode, they’ll find out what happens to the skeleton when the body doesn’t need it anymore – meeting the oldest human-ish skeleton ever discovered – Lucy.

Bad students of all ages are welcome. Expect brilliant teachers, captivating subjects but absolutely no homework.
