Today we continue with our ELI Early Years activities with 'Sensory treasure hunt; using senses to match objects with similar properties'.
Have you ever tried putting the different pebbles you can find into families? Here are some ideas: 'Rock Explorers; putting rocks into families'.
In this ELI Early Years activity, as Rock Explorers, children investigate a variety of rocks and sort them into groups. They can sort rocks/fossils into groups using a range of criteria e.g. shape, size, colour, how heavy they feel. They can then create their own forms of classification.
Other ELI Early Years activities can be found in our Cross-Curricular activities.
Continuing the climate theme of last week, today's ELI is 'Climate on arrival; if you suddenly arrived somewhere – what would tell you what the climate was like?'
This activity involves looking for features that might be indicators of the current climate. It explains the difference between 'climate' and 'weather'.
Related activities about climate and climate change can be found in our Resources and Environment category.
The new ELI today is 'Why coastal regions enjoy a milder climate than landlocked areas; modelling the ocean’s influence on climate by comparing the heat capacity of water and soil.'
This ELI is about building and testing a small-scale model of “ocean” and “land” to visualise the different heat capacity of water and land surface materials, as the main factor influencing oceanic and continental climates.

The two ELIs today are dealing with fieldwork, the first is about planning to obtain the best outcomes and the second is about safety.
(2) "The ‘What could hurt you here?’ approach to field safety; teaching how to keep safe during fieldwork and other outdoor activities".
The first activity considers what is it that makes a good educational experience. This then becomes a means of generating a checklist to evaluate pupil fieldwork experiences.
The second activity suggests ways to introduce fieldwork safety in ways that the group is likely to remember.

If you are out for a walk and see some rocks, do you wonder what they are? Here are some questions to ask yourself, 'Questions for any rock face 4: rock group (sedimentary or igneous): what questions about the type of rock might be asked at any rock exposure?'
Following the devastating effects of the floods in Texas, our ELI today is 'Flood through the window - what would you see, how would you feel? Pupils picture for themselves what a major flood through the window might look like.'

Our new ELI today is '‘Photo dating’; using photos to simulate the relative dating of the rock record.'
This activity has been devised to demonstrate the principles behind relative dating using zone fossils by substituting photographs, taken over a period of time within the experience of the students.
Related activities can be found in our Geological Time category.
We continue our series investigating geological time with '‘Looking so far into the Abyss of Time’; how to visualise the immensity of geological time...with a rope!'.
This ELI is an exercise to demonstrate the extent of geological time-scales and the need for meaningful geological reference points, obtained from fossils and other geological events, recorded in the rock record.
Go to 'Visualising deep time' in our Geological Time category for other related activities.
The ELI today continues our theme of geological (deep) time with 'But how old is it? Investigating radioactive dating of rocks and minerals'.
This activity investigates how radioactive (radiometric) or absolute dating of rocks and minerals works.
Related activities can be found in our Geological Time category - Visualising deep time.
Continuing our theme of geological time, the ELI today is 'The origin of the Earth – at arm’s length: the age of the Earth - with a good stretch of imagination.'
This activity teaches the great length of geological time in a fun way. It could be used to reinforce other methods of helping pupils to understand the concept of “deep time”, e.g. during a quick-fire revision session.
Related activities can be found in our Visualising Deep time, Geological Time category.
For the next few weeks, we will be considering geological time. The ELI today is '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.

Our new ELI today is the 9th in our Essential Minerals series - 'Essential Minerals for the Green Revolution – 9 Critical Minerals for the USA'
This Earthlearningidea defines the purpose of a national critical minerals list for the current and future needs of the USA’s industries and technology. This activity could form an extension of the ELI series on metal ores which are essential for the “new” technologies as well as the growth of existing industries.
Related activities can be found in our Minerals category.
We continue our theme of Essential Minerals for the Green Revolution with 'Rare Earth Elements; vital components in modern technology'.
This activity could be used in a lesson on the need to identify and exploit rare earth minerals in vital applications in many different fields, ranging from optics to energy saving devices and medical equipment. They are particularly important as catalysts in industrial processes and in the manufacture of strong magnets.
Other related activities can be found in our Minerals category.
Our ELI today is 'Essential Minerals for the Green Revolution – 6 “The Three Ts”; Tin, Tungsten and Tantalum'.
This ELI involves contrasting good practice in extracting essential minerals with illegal mining. It includes a brief survey of world production of the “Three Ts”.

We thought you would enjoy a fun activity as we end our magnetism and plate tectonics series. 'Hands on magnetic stripes; demonstrating how oceanic ridge magnetic stripes form, with several pairs of hands'.
Related activities can be found in our Plate tectonics and Magnetism categories.
Today's new ELI is 'Mapping Magnetic Anomalies; modelling the palaeomagnetic evidence for plate tectonic boundaries on the ocean floor'.
This ELI involves modelling plate boundaries (divergent and transform) from a simulated geomagnetic data survey. Students can describe how the pattern of magnetic stripes was collected from ocean exploration surveys and they can identify evidence of plate boundaries from the pattern of palaeomagnetic anomalies. They can also explain that magnetic anomalies and magnetic stripes are associated with reversals in the Earth’s geomagnetic field.
Related activities can be found in the following topics on our website, Magnetism, Plate tectonics and Oceanography.
Our ELI today is 'Human magnets! - modelling ancient and modern magnetic fields, using your pupils'.

Sink holes have been in the news in the UK over the last few weeks. Our ELI about this topic is 'Sink hole! Demonstrate sink hole processes in action'.
Sink holes commonly form over limestone bedrock, but also develop where the underlying materials are even more soluble, such as rock salt and gypsum deposits. This classroom activity models the dissolving of underground materials and the impacts this can have at the surface.

The new ELI today is 'When did the poles ‘flip’? Simulating how the Earth’s Geomagnetic Polarity Time Scale was established.'
This activity can be used to help teach students to understand how the pattern of ocean floor anomalies (magnetic stripes) can be dated; something they rarely appreciate. It might be used prior to a lesson on the palaeomagnetic evidence for plate tectonics on the ocean floor.
