Investigating how sediment is transported by water

'Rolling, hopping, floating and invisibly moving along; investigating how sediment is transported by water'.

Sediment is transported in water (rivers, the sea or currents in gutters) in solution, suspension, by saltation (bouncing along) and by traction (rolling or sliding along). As the sediment is moved along the grains bump into one another and bump against the river or sea bed. They gradually become ground down or eroded; any sharp edges are worn away and the grains become more rounded and smaller.
More activities about how sediment is transported can be found on our website.

Use the view from your local area to tune yourself into the local geology

The photo below shows teachers in Morocco trying out the Earthlearningidea 'The view from the site; using the view of the local area to tune yourself into the local geology'

All the ‘lumps and bumps’ of a landscape are either natural or the result of human activity; larger features can only be natural. This activity uses these features as clues to the underlying geology and geological structure.
Many more ideas to carry out in the field can be found on our website.

Simple demonstrations for use outside and ELIs for UK exams - 14-16 years

The ELI 'Fieldwork: interactive re-creation' suggests activities using simple transportable apparatus to simulate features in the field.

If geological features seen in the field can be 're-created' (simulated) in front of the exposure where they are found, then pupil understanding will be enhanced. This seems to be effective.
Many more ideas for field work can be found on our website.

Teachers in the UK - Geopix and Earthlearningidea have matched Earthlearningideas with the current GCSE specification.
The chart can be found in 'Teaching strategies' on the website.

From river sediment to stripey sedimentary rocks

The new ELI today is 'From river sediment to stripey rocks; modelling the build up of different layers of sediment as seen in sedimentary rocks'.

The activity is useful in consolidating knowledge about sediment transport and deposition by rivers. It helps pupils to interpret patterns they see in ancient river sandstones and to understand that the environment is constantly changing. It's also fun to do!
Lots more activities about rivers and their erosion, transportation and deposition can be found on our website by using the search engine or the index.

What questions about weathering might be asked at any rock exposure?

This series of Earthlearningideas suggests questions about geological processes that might be asked when standing with pupils looking at rock in a cliff, road cutting or quarry. The first of the series is about planning for fieldwork and the second is all about weathering.

This activity can be carried out using any exposed surface of rocks, including natural and artificial rock exposures, but also building stones, monuments or gravestones. Manufactured materials such as bricks, tiles and concrete also show the effects of weathering.
Other activities associated with weathering can be found on our website.

When the youngest rock is not on top of the rock sequence

Today's new ELI is 'Modelling by hand ‘when the youngest rock is not on top’; illustrating how rock sequences can have older rocks on top of younger ones'

While the ‘Principle of superposition of strata’ states that younger rocks are found above older ones, there are certain unusual geological conditions causing older rocks to be found on top of younger ones. Through this activity, pupils can model the unusual geological conditions where the ‘Principle of superposition’ does not apply.
This is one of a series of activities using modelling with your hands. Many activities related to the topics in this ELI can be found on our website.

Rock cycle discussion about a sand grain

Have you tried the ELI 'Sand on a sill; what will happen to a sand grain left on a window sill? – a rock cycle discussion'?

This discussion activity has been devised to encourage pupils to think about rock cycle processes in the context of the area outside their own school. By leading the small group discussion using questions such as: ‘What might happen next?’, ‘And then?’ or ‘Can you think of another idea?’, teachers should be able to encourage pupils to consider a range of different processes and products of the rock cycle and how these link to other Earth cycles, as described in the activity.
Many other activities about the rock cycle and its processes and products can be found in 'Teaching strategies' or in the index on our website.
You can also take part in the international research project.

What drives the tectonic plates?

This activity 'What drives the plates?' uses a pupil model to demonstrate that slab pull is the main plate-driving force.

Recent evidence has shown that the traditional view of mantle convection being the main driving force in lithospheric plate movement is probably incorrect. If it were the main driving force, then plates with the largest surface area would move fastest because they would have the largest area on which the mantle convection forces would act – this is not the case. However, those plates that have the longest subducting margins, with geophysical evidence of the deepest subduction slabs, do seem to be moving fastest – which is why this is now considered to be the main driving force. A fourth force that might be important is subduction suction where the old, cold oceanic plate subduction trench migrates towards the oceanic ridge pulling the over- riding plate behind it. Some geophysicists argue that this is an important driver of plate movement.
Many more activities about plate tectonics can be found on our website.
