Rock cycle discussion about a sand grain

Have you tried the ELI '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, as described in the activity.
Many other activities about the rock cycle and its processes and products can be found in 'Teaching strategies' or in the index on our website.
You can also take part in the international research project.
