Pressure underground and water pressure

'Under pressure; calculating the intense pressures underground'
This Earthlearningidea has been devised to give an idea of the intense pressures underground through measurement and calculation. It is presented in three systems of units.

The activity uses lab measurements of the force applied by different depths of sand and water to calculate their downward pressure and then uses these figures to extrapolate to likely pressures at crustal depths.








'Water pressure - underground; demonstrating how hydrostatic pressure increases with depth' 

This activity helps pupils to visualise the increase of hydrostatic pressure with depth that may have previously been explored in the activity mentioned above.

Environmental evaluation

This ELI is all about developing a strategy for evaluating the environment.


Help your pupils to appreciate and evaluate the outdoor environment by carrying out an environmental evaluation at different sites and comparing their results.
Many more good ideas for teaching Earth science can be found on our website.

Rocky play-park; design your own

New ELI just published - 'Design your own rocky play-park; telling the stories of rocks for everyone'. 
When you have designed your play park, you will need to present your ideas to the public. This could be by: a drawing like the one below; a plan (a view seen from above); a model; a website ...... you decide ..... and then present your ideas in the best ways possible.
Please send us your designs (email) and we will publish them on the website and on this blog.

'The present is the key to the past'

The ELI today involves applying ‘The present is the key to the past’. It is an outdoor activity using Earth science-thinking in reverse.


This activity helps pupils to build a picture of the past from the evidence preserved. It is one of many field work activities available to download free of charge from our website.

What evidence do living organisms leave behind in rocks?

'Trace fossils - burrows or borings' Living creatures often leave behind evidence of their activity in rocks, even if their actual remains are not found as body fossils. Clues may be obtained from living examples, which we can study in their modern habitats.


In this activity, pupils are invited to apply previously learned observations about the features of modern bivalve shells to the fossil record.
Many more activities related to fossils can be found on the website.
