The 100th anniversary of the Canadian Arctic Expedition this year.
The Royal Canadian Mint has created a website to mark the occasion.
(older browsers may need to be updated.)
Students can try the Heart of the Arctic game and "explore the mysterious and mythical north, find and collect over 50 items through puzzles and games, earn explorer badges, and unlock the lost coins!" http://www.heartofthearctic.ca/
There is also a teacher area for educational materials and activities.
