:: Tool 8
I found this video at Hulu which was easier to use than teacher tube. It is very short but explains clearly the Greenhouse Effect. I could use it as an engagement activity before the lesson.
I also found this video about Destructive Forces. Students can have a clear idea of the meaning of Destructive Forces. I like videos as a preview or closure in my lessons as long as they are not too long.
