Here’s how Skype A Scientist describes itself:

Skype a Scientist matches scientists with classrooms around the world! Scientists will skype into the classroom for 30-60 minute Q and A sessions that can cover the scientist’s expertise or what it’s like to be a scientist. We want to give students the opportunity to get to know a “real scientist”, and this program allows us to reach students from all over the world without having to leave the lab! We have over 2150 scientists ready to chat, and teachers can choose the type of scientist that will fit their classroom. Let’s start a conversation!
