Water pressure - underground

The new ELI published today is 'Water pressure underground; demonstrating how hydrostatic pressure increases with depth'. Pupils will be able to describe how the pressure of water increases with depth and also to explain how flow rates can be measured and compared.

Banana benders - simulate geological structures

Next time you eat a banana, try this first, 'Banana benders; using a banana to simulate geological structures'.
Bananas are commonly available, linear bars of material which deform readily and repeatedly to produce a whole series of natural fold and fault structures. They can be deformed at room temperature and will yield varying responses depending upon age and ripeness, but consistent results will be obtained.

Calculating the intense pressures underground


The new Earthlearningidea published today is an ELI+ 'Under pressure; calculating the intense pressures underground'. This 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.

IMPORTANT NOTICE

Earthlearningidea is moving to a new and more powerful server.
The content is identical.
The main entry point remains http://www.earthlearningidea.com.
Some users are accessing the old site with direct links to the pdf downloads.
Please will these users update their links and bookmarks as the old server will be turned off in about one week's time.

How do we know how extinct animals lived?

The ELI 'Curious creatures' uses fossil and modern evidence to work out the lifestyles of extinct animals. Pupils try to compare the features of animals today with
those of fossils. All of the creatures in the drawing above, lived in the sea about 515
million years ago before there were any plants or animals on land.
This is one of many activities to be found in the Evolution of Life category on our website.

Margarine mountain-building

Have you tried making mountains every time you make a sandwich? Try this ELI 'Margarine mountain-building'  The activity uses materials that pupils use every day to remind them how folds and mountain belts are formed, as surface and near surface materials are scraped up during plate subduction.

New ELI today - Environmental evaluation

We continue our Fieldwork series with 'Environmental evaluation; developing a strategy for evaluating the environment'.  This activity helps your pupils to appreciate and evaluate the outdoor environment by carrying out an environmental evaluation at different sites and comparing their results. They are given a scale to use in environmental evaluation, and then asked to apply this scale to different environmental circumstances, that can range from a local small environment to a panoramic view. If you are successful, your pupils may return from holiday and tell you they’ve been to a ‘9’ holiday destination!
