To make the polar bear snacks, I used vanilla ice cream, marshmallows, and Raisinets (the only brown candy I had on hand). Coconut would make nice "fur", but my kids would never eat it.
R does not care for marshmallows, so I just used whipped cream in place of the marshmallows. I added a little whipped cream "snow" to both plates.
Here are a few of the polar bear books we enjoy reading:
The Three Snow Bears by Jan Brett - This is a retelling of the fairytale The Three Bears, but it takes place in the Arctic and features an Inuit girl. We love everything by Jan Brett; her illustrations are simply brilliant.
Polar Bear Night by Lauren Thompson - A polar bear cub wakes in her warm den and sets out on a magical journey through her starlit world. This is a nice bedtime story with simple text and simple illustrations.
The Last Polar Bear by Jean Craighead George - The world is warming and the ice is melting, so Tigluk sets out to save the last polar bear. Obviously, this is a story of the plight of the polar bears threatened by global warming, but it is not at all scientific and does not even use the term "global warming". We enjoyed the story.
