This ELI involves a field simulation of the scratching of striations on bedrock by the debris frozen into an ice sheet, used to approximately calculate the thickness of the ice sheet and to discuss the assumptions made. The activity has been devised to enable pupils to gain a deeper understanding of the glacial processes which erode bedrock surfaces.

Pupils learn to describe spectacular and popular landforms sufficiently accurately that they can be drawn by someone else. This can lead to an in-depth understanding of the particular landform.
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.
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.
