This episode brings together three STEM Ambassadors who lift the curtain on what it is really like to stand in front of a classroom and try to spark an interest in engineering. Chris Chisman, Mark Forsyth and Margaret Rafter share the highs, the nerves and the moments that keep them coming back. You will hear how you should never underestimate a confident fourteen-year-old, how a Mexican wave became an unexpected but perfect way to show a scientific principle, and how, despite the terror, hard work and unexpected interactions, none of them regret getting involved.
