Teacher Discovery Teeth Whitening What Was The Name Of A Show On Discovery Channel?

What was the name of a show on Discovery channel? - teacher discovery teeth whitening

I'm doing a project in chemistry and my teacher told me that there is a television game 6-9 Thursday night on the Discovery Channel, which would have helped. It had something to do with the greenhouse effect and how this has fallen to the ground from 3 glacial periods. Any help and / or link to a video on this subject would be very grateful.
