Margarine mountain-building

Have you tried making mountains every time you make a sandwich? Try this ELI 'Margarine mountain-building'  The activity uses materials that pupils use every day to remind them how folds and mountain belts are formed, as surface and near surface materials are scraped up during plate subduction.
Many more free-to-download activities can be found on our website.

New ELI today - Environmental evaluation

We continue our Fieldwork series with 'Environmental evaluation; developing a strategy for evaluating the environment'.  This activity helps your pupils to appreciate and evaluate the outdoor environment by carrying out an environmental evaluation at different sites and comparing their results. They are given a scale to use in environmental evaluation, and then asked to apply this scale to different environmental circumstances, that can range from a local small environment to a panoramic view. If you are successful, your pupils may return from holiday and tell you they’ve been to a ‘9’ holiday destination!
Lots more ideas for out of the classroom work can be found on our website.

Teaching about fossils?

The Earthlearningidea team has introduced a new 'Fossils' category in our Teaching strategies so it is now very easy for everyone to find all the activities we have published so far about fossils. There is a separate 'dinosaur' section too!

A new group of ELIs is being written now called ELI (Early years) and that too will have some activities about fossils. We will keep you informed!
Please contact us with any requests.

Fieldwork: Applying 'the present is the key to the past'

The new ELI today is 'Fieldwork: Applying 'the present is the key to the past'.
This five-phase outdoor activity is used to explain how Earth scientists use the Principle of Uniformitarianism, often simply stated as ‘the present is the key to the past’, by considering the present environment and thinking how it might be preserved geologically.
It is one of many outdoor ELIs - all listed on the website in activities related to the new ELI and in 'Teaching strategies' under 'Fieldwork'.

Danger - quicksands!

'Danger - quicksands! Why do some rocks give way when it rains hard?' This ELI investigates pore water pressure in a sediment and demonstrates how raised pore water pressure can weaken apparently strong rocks/sediments, causing subsidence in buildings or landslides.
Many more such activities can be found on our website; all are FREE to download.

Trace fossils - burrows or borings

Our latest Earthlearningidea, published today, is 'Trace fossils - burrows or borings; what evidence do living organisms leave behind in rocks?' This activity is best used immediately after pupils have worked though the ELI activity 'Sea shell survival - how are common sea shells adapted to their habitats?' Adaptations to different habitats are reflected in the shell structure of bivalves. This understanding is applied to working out what ancient environments were like from the trace fossils left behind by similar organisms. Can you distinguish between a burrow and a boring?
This is one of many ELIs about fossils; all can be found in the Evolution of Life category on our website.

Eruption of Krakatoa

This is a very popular ELI but it can make a watery mess! 'The balloon goes up at Krakatoa' The activity uses a tank and a balloon to simulate the huge tsunamis caused by the eruption of this volcano.

 The eruption of Krakatoa (or Krakatau to use its Indonesian name) was the first major volcanic eruption that was investigated and recorded scientifically. It is described as ‘colossal’ on the Volcanic Explosivity Index (VEI), having ejected more than 10 cubic km of material. (The eruption of Tambora in 1815, also in Indonesia, is described as ‘super-colossal’ on the VEI, having ejected more than 100 cubic km of material, whilst the eruption of Taupo, New Zealand about 28,000 years ago, was ‘mega-colossal’, ejecting more than 1000 cubic km of material – but both of these erupted before scientific records). Thus we have reasonably good scientific evidence for the effects of the Krakatoan eruption, even if we still don’t understand the exact mechanisms of eruption and tsunami-generation.
This is one of many innovative Earthlearningideas on our website
