Try our new Earthlearningidea 'Squeezed out of shape: detecting the distortion after rocks have been affected by Earth movements' Ask your pupils if we can ever tell by how much a rock has been squeezed by Earth movements. One way is to look at fossils in deformed rocks. The original shapes of these are usually well known, so they can be used to work out the extent to which they have been deformed. If the fossils have been deformed, then so has the rock in which they are found.This is a very popular activity in the UK. Let us know how you get on - - send us some photos of your results.
