'A world in a grain of sand’ - what can a grain of sand tell us about its past?
This ELI is a ‘thought experiment’ on erosion, transportation and deposition.
For younger ages, it could be used to write a story or draw a cartoon about the life of
Sandy Grain. Start with a grain of sand on a beach, and describe where it has come from and what will happen to it.

We are continuing our latest series with 'Essential Minerals for the Green Revolution – 4 Graphite: from a pencil to the electric car!'
Other related activities in our 'Essential minerals' series can be found in the ELI Minerals category.
Today's ELI is 'A core activity; piecing together evidence for the composition of the Earth’s core'.
This Earthlearningidea asks pupils to examine and discuss the evidence for the composition of the Earth’s core.
Related ideas can be found in our Earth Materials category in 'Structure of the Earth'.
The new ELI today is 'Shadowlands; simulating the effect of the Earth’s core on earthquake waves'.
This is a simulation exercise to demonstrate that the shadow zones created by earthquake waves are affected by the size and physical properties of the Earth’s liquid outer core.
Other related activities can be found in two categories: 'Structure of the Earth' and 'Earthquakes'.
Today, we continue our edible theme with 'Boring chocolate! What can boreholes tell us about the Earth?'.
This activity can be used in any science or geography lesson about finding what is beneath the Earth’s surface, including the search for natural resources and understanding past environments.
You can find related activities in our Earth Materials, Earth's structure category.
The new ELI today is 'Folds and faults with puff pastry and chocolate; understanding folds and faults in cross section and on a geological map'.
This activity models the formation of folds and then of faults using the Catalonian pre-Pyrenees as an example in the real world.
It's in the ELI category of Deformation - folding and faulting where you can find a wide selection of related activities.
In this Earthlearningidea, several photographs are used to stimulate discussion about possible rapid geological processes in the past which might have had “catastrophic” outcomes if there had been humans on the Earth at those times.
Explore the category 'Natural Hazards' for many other activities about catastrophic processes.
