What it teaches
The main habitats and which animals belong to them. Underneath it is the first idea of adaptation: an animal is not in a place by accident, it is there because something about it suits the place.
How it works
An animal appears and the habitats are the answers. Three levels change the length of the round and the number of habitats offered.
The help names the feature rather than the place — thick fur, webbed feet, the ability to go without water — so the answer can be reasoned to.
What to look for
Ask "what about it helps it live there?" rather than "where does it live?". The second question has one answer and the first one has a conversation in it.
