This week we started talking about the impact of the volcanic eruption in Iceland. Real-time science connections! This led to Earthcast, a 24 hour webcast on Earth Day, April 22. The Earthcast will be hosted on Worldbridges on the Earthbridges channel. We were able to get a few more people to sign up to participate, in fact all three Conversations hosts will be participating! What will your school, organization or you do on Earth Day?
