Since we are planning our trip northward (to Alaska) We have been studying the state with our kids. I would like to share what we have learned. (I have young children so it wasn't real in depth.)

Day 1:

Alaska Facts

State Flag, State Bird, State Flower, and State Seal

We found these and more at http://homeschooling.about.com/cs/unitssubjgeog/a/susak.htm

Day 2:

Alaska Indians

We made totem poles out of egg cartons

Great info on this site: http://www.oregontrail.net/~thesmiths/iditarod/people.html

Day 3:

Iditarod Race

Watched a Sled Video here http://www.trailriverhuskies.com/ .
Read Togo by Blake

Day 4:

Weather

Make snowflakes www.learnwhatsup.com/prc/holiday/christmas/crafts/borax_crystal_snowflake.html

Northern Lights http://www.exploratorium.edu/learning_studio/auroras/index.html

Day 5:

Artic Animals

We watched all kinds of wonderful videos that were available at our local library.

I also found this Sea World  site cool http://www.seaworld.org/fun-zone/fun-guides/arctic/arctic-adaptations.htm

That is a basic layout of what we have done. Lots more still to learn!
