Investigating a grain of sand

The new Earthlearningidea today is "A world in a grain of sand"; what can a grain of sand tell us about its past?

This ELI is a ‘thought experiment’ on erosion, transportation and deposition. It can be used for all ages, to link studies in science or geography with the medium of literature. There is a video clip to accompany the activity.

Other related activities can be found in 'ELI Early years' or in 'Earth energy - sedimentary processes'.
