in what? if I started watching my mice now they'd sleep the whole time. I cleaned and rearranged their cage yesterday and watched them then, they were extremely interested in everything in the cage, running around and sniffing/nibbling it all - especially the new items. They're also quite interested in me if I put my hand in their cage. They run up to me and sniff/nibble then run away and come straight back to do the same thing.

I wouldn't really know what to describe here tbh, this assignment sounds hard! I guess you could talk about things like closing eyes, opening mouths, pointing ears back etc.

They stretch out a lot when approaching things from a distance, Hunch up when eating, they tend to flatten when they're on unsteady ground.

two of my mice I never hear a peep out of, one squeaks quite loudly if they're in bed and the others move suddenly and she has a kind of chattering whenever she's exited - like if you rearrange the cage.

I take it you have enough.

not all mice are vocal

were there any more specific questions you had?
