No problem--there's a "write-protect" switch right on the back of the hard
disk, only it isn't documented as one.  Just take a magic marker and write
"write-protect" over the word "off."

Well, I suppose you did ask for "read only," though...there is a CDA by
Glen Bredon that will write-protect *all* your online devices under
ProDOS 8.  I believe you have to manually choose the CDA every time you
enter P8 to get the write protection turned on, so it probably won't
help you keep the kids from messing up your drive.  The power swtich
solution sounds very practical, though.
