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.

Lots more teaching ideas can be found on our website by using the search engine or the index.
