We're doing Life Science this year, so we started out our studies with a Let's Read and Find Out book that Norah could read herself. It answers the question, "What's Alive?"
The little girl in the book draws pictures of things in her house and her yard, then she puts pictures into groups of living and non-living things.
When we were done reading and discussing the book, we did the same thing with the pictures in our picture file. We organized them into groups of living and non-living things.
