Electrical ground probing

Following on from last week's post about remote sensing, this week we have 'Electrical ground probing; measuring the electrical resistance of the ground to find buried objects.'


The activity models the principles involved in surveying by electrical methods. Such techniques are frequently used in mineral exploration or in archaeological surveying. Forensic scientists also use the method to investigate disturbed ground in the search for objects buried by criminals.

Modelling remote sensing geophysics

The new Earthlearningidea today is 'Modelling remote sensing geophysics; using a mock gravitometer and magnetometer set up in the classroom'

This activity involves using a mock gravitometer and magnetometer to demonstrate the principles of the remote sensing of gravity and magnetism. It is an ELI+ activity. This method models how density and magnetic anomalies are identified by geophysical remote sensing. Data from such geophysical sensing is used to plot gravity and magnetic anomaly maps, like the ones shown above and explained in the activity.

A thought experiment to investigate carbon cycle processes

‘Tag’ a carbon atom – and explore the carbon cycle' is an Earthlearningidea thought experiment to investigate carbon cycle processes.


We can ‘mark’ genes with glowing colours to discover how they work – and so can produce mice that glow bright green. We can also tag organisms, from butterflies to whales, to find out about their lives and movement. Help your pupils to understand the carbon cycle by pretending to ‘tag’ a carbon atom so that they can ‘see’ it as it is carried around different parts of the carbon cycle.

Fracking: recipe for the perfect fracking fluid

The new ELI today is 'Recipe for the perfect fracking fluid; make your own fluid to fracture hydraulically (frack) methane-bearing shale'.


This is an activity to examine the hydraulic fracturing method and the purposes of the different constituents of the fracking fluid. Pupils are encouraged to think through the purpose of the constituents of the fluid used for fracking, and the whole fracking concept.

Why is the fossil record incomplete?

'Shell shake – survival of the toughest; why is the fossil record incomplete?'

Many organisms are destroyed by being eaten or by being broken up into tiny fragments by moving water, or by processes of changing the sediments to rock. This activity demonstrates that a slab of apparently well-preserved fossils may not present a true record of all that lived there, so caution is needed in reconstructing the ancient environment in its entirety. A fossil assemblage may contain evidence about the environment in which the organisms lived, and what happened to them after their death.

Geo-literature: create your own geo-poem or story

Today's new Earthlearningidea is 'Geo-literature: poems and stories inspired by all things ‘geo’. Create your own geo-poem or story'

Much of our great literature was and is inspired by the natural world. This activity encourages pupils to write imaginatively about a topic they have studied in Earth science or geography. It creates a cross-curricular link between the sciences and arts. Send us your creations and we will publish them on our website.

Treasure hunt with a difference.

This Earthlearningidea is fun for young children especially if it can be played outside, 'Sensory treasure hunt; using senses to match objects with similar properties'.


This activity has endless potential and can be used in many ways.
Lots more ideas which can be used in the holidays can be found in the 'Children's Fun' section of our website.
