Simple Rock Identification

'Rock detective – rocky clues to the past; investigating your local rocks to find out how they formed'.


This activity is all about sorting rocks according to their properties, which depend upon how they were formed. Pupils use the characteristic properties of a set of rocks to sort them into sedimentary, igneous and metamorphic rock groups. This works reasonably well for most rocks, but there are exceptions which are explained in the activity.

Other ELIs about rocks can be found in the Rocks section of Earth Materials.

Teaching geology to students with visual impairment (VI)

Our new ELI today is the third in a series of 'Teaching geology to students with visual impairment (VI) - modifying geological materials for students who cannot see'.

Using the three ELI activities in this series, pupils with visual impairments can actively participate in learning geology. They can engage with real geological materials used so frequently when teaching the subject. They can also share in learning, using these models alongside visually acute students.

The other activities in the series are in the Cross Category topics lists.
