Sorting, naming and putting rocks into the rock cycle

Today's new ELI is "From ‘Rock detective’ to ‘Laying out the rock cycle’: investigate rocks to sort them into groups, add them to the rock cycle and name them"

This activity uses sorting cards to link two Earthlearningideas together - ‘Rock detective’ and the ‘Laying out the rock cycle'.
By doing this pupils can investigate a range of rocks from first principles, identify and name them and then build understanding of them in a rock cycle context. It helps them to name rocks, not just by recognising them but by using first principles of observation and investigation.
A variety of activities about rock types and the rock cycle can be found on our website by using the alphabetical index.

Sea shells and their habitats

Sea shell survival; how are common sea shells adapted to their habitats?

This activity gives an an introduction to the relationship between the features of shells of bivalves and their habitats. Many marine animals are specially adapted to give them the best chance of survival in their habitats. These adaptations are reflected in their shell structure. This ELI may be used as a prelude to determining ancient environments from the fossil remains or from the traces of similar organisms in rocks.
Many more activities related to fossils and past environments can be found on our website in the 'Evolution of Life' category.

Exploring current flows through straits

Today's new ELI is 'Exploring current flows through straits; testing the L. F. Marsili model of Bosphorus currents (1680)'

This Earthlearningidea models the flow of seawater of different densities through straits, e.g. the Bosphorus. It addresses several concepts within Earth sciences (concentration, density, diffusion) by means of modelling typical of a science investigation, with an example taken from the age of the Scientific Revolution.
Other activities about ocean currents, sea water density and famous scientists can be found on our website either by using the search engine or the alphabetical index.

Ice power

'Ice power; freezing water in a syringe to measure the expansion'

This activity may be used in either science or geography lessons on weathering. It can also be used in discussions of molecular theory and changes of state. For the most accurate measurements, use pure (distilled or de-ionised) water at as near to 4 degrees C as possible.
More innovative ideas of how to teach weathering or glaciation can be found by searching our website.

Mineral or not?

New ELI today is 'Mineral or not? Discussion about what is a mineral and what is not'.

This activity is centred around pictures or samples to enable pupils to distinguish between a mineral in the Earth science sense and other ways in which the term is commonly used. There is much confusion about what the word means.
Many other activities about minerals can be found on our website.

Sedimentary structures - graded bedding

'Sedimentary structures - graded bedding: make your own graded bed – one depositional event, but with coarse to fine sediment'

This ELI is a teacher demonstration (or a small group activity) showing the origins of graded bedding. It can be used in any lesson dealing with the origin of sediments and the interpretation of past environments.
Our website has many more activities related to sedimentary structures.

When are soft rocks tough, and hard rocks weak?

New ELI today - 'When are soft rocks tough, and hard rocks weak? A discussion about the toughness/resistance of rocks in different places'

The simple idea, which generally holds, of tough rocks forming hills and headlands and weaker rocks, valleys and bays, does not always apply. This activity looks for evidence of when and why it is not always true.
Many activities related to rock resistance can be found on our website.

Bringing a fossil 'back to life'

A popular ELI is 'Running the fossilisation film backwards; bringing a fossil ‘back to life’'

This is a thought experiment, including possible re-enactment, to recreate the likely ‘final moments’ of an animal which later became a fossil. The activity provides examples of how to ‘run the fossilisation film’ backwards to help pupils to visualise what a fossil may have looked and acted like during life and in the few moments before death.
Many more fossil-related activities can be found on our website.

Jelly Babies (TM) and Geological maps

The new ELI today is an ELI+ written for older pupils who are learning about 3D geological maps. 'The sliced Jelly BabiesTM approach to understanding 3D geological maps; use Jelly BabiesTM cut at the dip angle to highlight structures on geological maps'

This activity shows the dip of fold limbs on a geological map using sliced jelly sweets to show bedding plane dips.

Choose the power source

'Which power source? – solving the crisis in Kiama: searching for all the power sources that could be developed in a mythical country'

Pupils study a map to find clues to the different energy sources that could be exploited in a mythical country. Possible power sources with some of their advantages and disadvantages are shown in a table provided in the activity.
Many more Earthlearningideas related to power sources can be found on our website.

Evidence given by dinosaur footprints

'The meeting of the dinosaurs - 100 million years ago; the evidence given by dinosaur footprints'

Fossil tracks, such as footprints, can provide a great deal of evidence about the environment at the time when they were made and about how the animals lived and moved.
Other activities involving dinosaurs can be found on our website.

Catastrophic processes - a discussion of sedimentary beds

The new ELI today is 'If a sedimentary bed were laid down outside now – what would it be like? A discussion of beds and catastrophic processes'

A class discussion to develop the idea of a ‘bed’ of rock and how beds might be deposited catastrophically. The type of bed that could be deposited very much depends on the altitude and character of the area. Both likely and less likely scenarios are described in this ELI..
The activity can be used with any age of pupils or adults.
Many more Earthlearningideas in the Natural Hazards caregory can be found on our website.

Rocks music; create your own instrument

The new Earthlearningidea today continues our cross-curricular theme with 'Rocks music; create your own geo-instrument'

For this activity, the pupils should be able to identify the rocks they use and should be able to say whether they are sedimentary, igneous or metamorphic. This activity fits in well at the end of a topic where pupils can explore other aspects of the subject of study. It encourages creative thought and breaks down barriers pupils may make between scientific subjects and the arts.
Other cross-curricular activities can be found on our website; geo-art, geo-literature and Earthquakes in art. Geo-music will be published later this year.

Fold mountains: the Himalayas in 30 seconds!

'The Himalayas in 30 seconds! Making a miniature fold mountain range in an empty box'

This activity models how lateral pressure can squeeze rocks into folds and faults, and imitates the way in which fold mountain ranges are formed. It could be used to extend a physics lesson on forces, or to aid understanding of the ways in which Earth’s surface features affect weather systems such as the monsoon, in geography.

Urban fieldwork - the stories told by building stones

The new ELI today is 'Urban fieldwork – the stories from materials, colours, lines and shapes; find out the stories told by materials used in building and for decoration'

In this activity. pictures focussed on colours, lines and shapes are used  to begin to tell the stories of the stones used in urban areas. This urban fieldwork helps to show that, wherever stones are found or used, the features within them can be used to tell the stories of how they formed, and sometimes, how they were later deformed.
Many activities related to buildings stones and to field work can be found on our website.

Investigating soil erosion

'Why does soil get washed away? Investigating why some farmers lose their soil through erosion whilst others do not'.

Soil erosion is a normal part of the natural rock cycle, but it can become a major problem in many rural areas where people depend on the land for their livelihood. This activity provides the opportunity to investigate some of the factors involved in limiting soil erosion. Video clip.
Your pupils can extend the activity by doing some soil painting too.
