I received this notice from NOVA today about the Arctic Passage. NOVA/PBS programs have websites that provide all kinds of resources for teachers. See the teacher resource website for this program @ http://www.pbs.org/wgbh/nova/arctic/. This website provides information about the program including: watching the program online, related books & links, teacher guides & lesson plans, transcripts, slide shows and interactive activities.
I also found another great teacher website about snow:
National Snow & Ice data Center
