Angela and Simon flatten a lump of clay and Simon leaves an imprint of his foot in it. Simon shows a fossil of a fish. Simon dresses as Professor Simon and finds the name of the day in the sand-tray. He then discovers the long lost tiny tea set of the long lost tea-drinking people. Angela shows a Velociraptor, Apatosaurus and Tyrannosaurus Rex, made of boxes. These become part of the Play School Museum showing the history of Earth.
