Ice-thickness from scratch: visualising past processes by calculation

The new ELI+ is 'Ice-thickness from scratch: visualising past processes by calculation; modelling glacial striation-formation by calculation – thinking through the assumptions'. 

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, such as the one shown in the photo.
Other activities about glacial erosion can be found on the website.
