The shelter wants to have residents download stuff to flash drives they are giving the residents.  Googling, I find nothing directly on point.  Any help is welcome.

If you want to prevent the user from writing to the hard drive, you might try using the guest session capability mentioned in another post and setting the system so it gives no permissions to the guest user, something like...

sudo mkdir -m ---------- /var/guest-data
Please see:
https://help.ubuntu.com/community/CustomizeGuestSession
and

Good luck.
