What can boreholes tell us about the Earth?

The new ELI today is 'Boring chocolate!' What can boreholes tell us about the Earth?

This activity can be used in any science or geography lesson about finding what is beneath the Earth’s surface, including the search for natural resources and understanding past environments. As you can imagine, investigating their own edible boreholes is much enjoyed by students of all ages.
