I also of course love using YouTube videos. This definitely increases buy-in - the kids LOVE watching the animals in action. I have pre-watched all of these videos and can give you the teacher thumbs up!
We also always complete a diagram of a polar bear where we label different parts of their body and discuss why they need these body parts to survive in the arctic.
