The Sun has just launched a new educational website (yes, really - the
Sun newspaper) which uses their undoubtedly talented headline writers
to produce front pages (and backing material) about significant dates
in history.
It includes a number of front pages for science discoveries that could
make useful starting points for some Science in Society topics.

They claim that the information has been checked by experts (and site
is in partnership with the commercial arm of the Science Museum).
Worth a look perhaps.
Enjoy
