came to talk to us about bones.
He's a vet and we had lots of questions for him about animals and their bones.
Adivay knew that we can see bones by looking at an xray.
Lyra is looking at a dog's leg bone that has been put back together after being broken.
This is a horse's jaw bone.
This is part of a spine that has been broken.
