Classroom Ideas

Could be used to introduce students to the techniques used to determine what riches lie underground and the geological processes which create them. Given a decent atlas the students could produce a simple sketch map to show the extent of the Caledonian mountain ranges and suggest that if gold exists in Ireland then where else (which other countries - atlas skills) could it be worth looking in?
