How to look at rocks

Thanks to the currently ongoing Covid crisis, I have been finding the need to prepare teachers with non scientific backgrounds to be able to deliver more technical lessons to their class bubbles.

I made this powerpoint as a way of teaching staff some of the basics in rock classification, identification, and interpretation. This powerpoint should hopefully help a lay person the things to look out for when teaching a class about rocks.

I cover the main criteria that can be used to distinguish between the different rock types, how to produce an annotated sketch of rock samples, and how to interpret some of the basic information that a rock can provide about its origin.

Naturally, this can be used to teach pupils too, but you will have to provide your own rocks i’m afraid.
