We continue our theme of the Greenhouse effect with 'Is the greenhouse effect happening outside today? A classroom discussion to consolidate understanding about the greenhouse effect'.
This ELI involves a discussion to reinforce learning and to counter misconceptions about the greenhouse effect.
Related activities on climate change can be found in the 'Climate change' category.
The new ELI today continues our climate change series with 'Greenhouse effect in a bottle: how to simulate the effect of increased CO2 level on Earth's temperature'.

Because of the solar eclipse which is happening today, we are publishing 'Why does the Sun disappear? Demonstrate what happens when the Moon hides the Sun'.
Related Earthlearningideas can be found in our 'Eclipses - solar and lunar, Earth in Space' category.
Our latest ELI+ is "‘Earth’s oxygen thermometers’ - simulating how ocean sediment and continental ice cores record past changes in Earth’s temperatures."
This activity is a simulation of how oxygen isotope analysis of deep-ocean sediments and continental ice-cores provides a record of past changes in Earth temperatures.

The ELI team is now publishing three more activities which will be useful when teaching climate change. The first is: 'Ocean acidification – The other CO2 problem; see how acidified water affects calcareous marine organisms'.
A demonstration, involving blowing into neutral water to produce a weak acid. Powdered seashells are added and react with the acid, as a quick-acting laboratory example of how an acidifying ocean affects the life of many marine organisms.

The new ELI today is another in our very popular 'Picturing . . .' series - 'Picturing Landforms -1; visualise and draw landforms from a verbal description'.
Other activities in the series can be seen in the 'Picturing . . .' table.
This activity is all about sorting rocks according to their properties, which depend upon how they were formed. Pupils use the characteristic properties of a set of rocks to sort them into sedimentary, igneous and metamorphic rock groups. This works reasonably well for most rocks, but there are exceptions which are explained in the activity.
Other ELIs about rocks can be found in the Rocks section of Earth Materials.
Our new ELI today is the third in a series of 'Teaching geology to students with visual impairment (VI) - modifying geological materials for students who cannot see'.
Using the three ELI activities in this series, pupils with visual impairments can actively participate in learning geology. They can engage with real geological materials used so frequently when teaching the subject. They can also share in learning, using these models alongside visually acute students.
The other activities in the series are in the Cross Category topics lists.
Keeping our theme of limestone - - '‘I’m pure calcium carbonate’ – the calcium carbonate question; a discussion focussed on common misconceptions about calcium carbonate'.
New ELI today is 'Make a mini lime kiln and discover limelight; investigating the results of heating limestone.'
This ELI is a pupil activity to decompose limestone by heat and to discuss the uses of the resulting quicklime. It's a good activity for science, geography or environmental science classes.

'Mineral or not? Discussion about what is a mineral and what is not'.
This is an activity 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.
Many related activities about Minerals can be found in the Earth Materials section of our website.
The new ELI is the last in the current series of Essential Minerals for the Green Revolution. It is "Essential mineral – critical mineral: what is the difference?"
The full series of 'Essential Minerals for the Green Revolution' can be found in the Minerals section of Earth Materials on our website.
The new ELI today is 'Counting to one million? - trying to imagine the enormity of geological time'.
'What is it made of? Relate each mineral or rock to the everyday object containing it.'
