Recipe for a magnetic Earth and a magnetic detector

Our new Earthlearningidea today is 'Recipe for a magnetic Earth and a magnetic detector: using a stress ball and small magnet, with a needle and thread to model magnetic Earth'

If you want to use the ‘Magnetic Earth’ Earthlearningidea in your teaching, but would like each group of pupils to try it out for themselves, then this version can be put together very cheaply. Other activities associated with Earth's magnetism can be found in the alphabetical index or by using the search engine.

Clues in sediment which bring an environment to life

'What was it like to be there? – clues in sediment which bring an environment to life: bringing a depositional environment to life using evidence from sedimentary structures.' 

This ELI asks ‘deep questions’ about sedimentary structures to help pupils to visualise the environment in which they formed.
Many more activities about sediment deposition and sedimentary structures can be found on our website, either by using the alphabetical index or the search engine. The former gives a list of such structures with an activity for each.

Hand modelling of compression, tension and shear in the Earth

Today's new Earthlearningidea is 'Modelling Earth stresses with your hands; hand modelling of compression, tension and shear in the Earth'.

This is a class activity to help pupils to visualise and remember the types of stress in the Earth through modelling with their hands. The results of the different types of stress are seen in the deformation of a cube, shown in the diagrams above.
Activities to demonstrate these stresses can be found on our website. The easiest way is to search for 'Stresses in the Earth' in the alphabetical index.

Understand the enormity of geological time

Use some sheets from a toilet roll to make 'The toilet roll of time; make a geological timeline to take home'

This activity has been devised to address the common lack of knowledge about geological time. Research has shown that many people have no idea of the great length of geological time nor of the order of the key events during the geological history of the Earth.
Many more activities about deep time can be found on our website.

Atmosphere and ocean in a lunchbox

Our new Earthlearningidea today is an adaptation of a very popular teacher demonstration, developed into a smaller scale model for pupil use - 'Atmosphere and ocean in a lunchbox; a model for all pupils – of hot, cold and cloudy density currents'

This activity can be used to introduce or reinforce understanding of atmospheric and/or ocean processes or, if used interactively, as an effective way of developing thinking skills, as outlined in the activity.
Many more ELI models can be found by searching our website.

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.

Modelling unconformity – by hand

Today's new Earthlearningidea is another in our 'hands' series - 'Modelling unconformity – by hand; using your hands to demonstrate how unconformities form'.

The formation of angular unconformities involves a range of processes operating over different time spans. Modelling these with your hands, whilst explaining the processes and the timings involved, helps to consolidate learning.
Other activities relating to Earth processes and unconformities can be found on our website by using the search engine or the alphabetical index.
