Geologists need to know what is underground. Digging up huge areas of land is not an option open to them. Instead they use drilling machines to extract "core" samples from various sites in the area they are researching. The "cores" can then be analyzed to determine the composition of the earth's interior.
This activity can be used as a teacher demonstration but will likely be more effective if done in groups or as individuals.
A similar kind of activity can be done using cupcakes made with various types of cake mixes (these would simulate different earth layers.)
