Sand on a sill - a rock cycle discussion

The new ELI today is 'Sand on a sill; what will happen to a sand grain left on a window sill? - a rock cycle discussion'

This discussion activity has been devised to encourage pupils to think about rock cycle processes in the context of the area outside their own school. By leading the small group discussion using questions such as: ‘What might happen next?’, ‘And then?’ or ‘Can you think of another idea?’, teachers should be able to encourage pupils to consider a range of different processes and products of the rock cycle and how these link to other Earth cycles.
This Earthlearningidea is an international collaborative research project 
The project derived from a discussion on research into Earth science education at the International Geoscience Education Organisation conference, GeoSciEd VII, in Hyderabad, India in 2014.
