Many people don‘t realise that, to build our buildings, to construct transport links and to make dams and reservoirs, we have to extract millions of tonnes of material from the ground — and that this comes from quarries. Most people would not like a quarry in their 'backyard‘, but quarries have to be sited where the materials are found underground, and not too far from where they are needed, because it is very expensive to transport bulk materials like quarry products for long distances. So, some rock, sand and gravel quarries and clay pits have to be sited near towns and cities. If they are sited near towns and cities, because of the strict planning regulations in many countries today, not only would the quarry be hidden by screens when the quarry was in action, but it would be landscaped afterwards and often would be used later as an amenity by local people (water park, golf course, etc.) or for waste disposal.
There are lots of Earth-related activities for you to try at Earthlearningidea.

Lots of ELIs were tried and teachers took home copies of the activities.
We really like the one shown in the photo where our suggested foam balls have been replaced by marshmallows. You can eat them afterwards too; what a good idea! This idea will be included in the 'extension ideas' for the activity 'Metamorphism - that's Greek for 'change of shape' isn't it?'

The new activity 'Riches in the river' is an investigation into how valuable ores may become concentrated on river beds. Pupils will explore the importance of differences in density of sand and valuable ore, to see how the ores may become concentrated by the action of moving water.
Pupil learning outcomes: Pupils can
- explain how moving water can separate particles of different density;
- predict where best to look for gold and dense ores on a river bed;
- explain how density differences can be used to separate valuable ores from less dense waste in a commercial situation.
Try this or any of our Earth-related activities and please let us know how you get on.

Not only is Jothi Rajan doing the translations but he is also demonstrating Earthlearningideas at workshops. Next week, on 3rd and 4th December, he is organising a two-day orientation cum workshop for rural schools science teachers of Usilampatti Educational District. The participants are science teachers of 9th standard class handling Tamil Medium classes. The Earthlearningidea team wishes Jothi and his students every success at this event! We hope we shall be able to publish some photos afterwards.

Pupil learning outcomes: Pupils can:
- test the porosity of a model in the classroom;
- work out the percentage pore space;
- explain why some rocks are porous;
- apply their knowledge of rock porosity to real world situations, such as oil and gas reservoir rocks and rocks containing water (aquifers);
- (in the context of other activities from the Earthlearningidea series) explain the difference between porosity and permeability.

"I often use this as a 'challenge' activity, where student teams compete to see who 'best' cleans the water. I offer the students a choice of possible items to filter and let them design their own filters using different layers. The biggest challenge is getting the blue food coloring out of the water. This exercise really works well with the cut off bottles as funnels. If you have a microscope, students can easily see some of the small organisms in the water and you can incubate your own by putting grass clippings in water and letting it sit."
These are positive and enhancing comments which we have published in our 'Extension Ideas'. Thank you Mary!
We shall be very pleased to receive any other suggestions to add to these to take the investigation further.

Ask the pupils if they have ever built a big sandcastle. What was the steepest angle they could build the side walls of the castle? Could they make a steeper wall if the sand was dampened? Questions like these go well beyond the playground or beach. Many people have been killed by the collapse of unstable slopes of loose rock or sand. This activity investigates the factors which affect the angle at which loose materials rest before they begin to slide.
Please let us know how your pupils get on by writing a comment on this post or contacting us by email.

- A dinosaur in the yard
- Dinosaur death - did it die or what it killed?
- How to weigh a dinosaur
- The meeting of the dinosaurs - 100 million years ago.
All of these activities use trace fossils.

First of all your pupils need to do some 'trail-thinking' by asking themselves why would the animal have been on the sand, in which direction was it moving, how would it have been moving, how fast, how deep would the trail be, would it have been straight, would the animal have rested and how could the trail become fossilised?
When pupils have completed this activity, they will be able to describe how animals of the past might have moved, use their descriptions to make appropriate trail marks in damp sand and explain how the trails they have made give information on how the animals moved in the past.
Of course, they can make many types of trails from those left by trilobites to those of dinosaurs.
We should be very pleased to receive your pupils' ideas and photos of their trails, if possible.

- What would they see?
- What would be happening to the ground?
- What would be happening to the buildings and trees?
- What would people be doing?
- What would it be like inside their building?
- How would they feel?
- What would they do?
- What would they tell their friends to do?
- What do they think caused the earthquake?
- Can they predict when the next earthquake will happen?
Please send us the best of their stories and we will publish them. Maybe they have some true stories to tell?

Trace fossils can give very valuable information on the lifestyles and environment of the organisms that created them.
The photo above shows a footprint from a large dinosaur. An impression would have to be taken of this for it to be used for this Earthlearningidea.

Note - the measurement of the lead letters can be done with a tyre depth gauge if a micrometer is not available. Participants could also look to see if there is any difference in the weathering of one side of the stone from the other side; this may indicate the influence of the prevailing wind. In the U.K. the latitude and longitude of the site can be found on Ordnance Survey maps so you don't need GPS.
The weathering rates of gravestones are an indication of changes in the acidity of rainfall between locations and over time. The acidity is affected by air pollution and other factors, and could be used as a measure of changes in climate and pollution levels.
'Weathering - rocks breaking up and breaking down' is the Earthlearningidea activity concerned with the various ways rocks are weathered.

AEON EarthWISE is currently preparing two teacher workshops in the first week of August as part of National Science Week. The organisers plan to reach 80 teachers from all over the Free State. Two activity books, (one for Intermediate Phase and one for Senior Phase), have been set up to distribute to the teachers during these workshops and Earthlearningidea activities form a huge part of these books. ELI activities fit right into the National Curriculum. The activities have been printed in their pdf format and put into the Appendices in the back of the books.
The current coordinator says, "I can't wait to show it to the teachers, because I truly believe that doing these activities in the classroom can be nothing but beneficial to the learners. So yes, we are definitely putting your ideas to good use. Thank you very much for them!"
The Earthlearningidea team is delighted to hear about this venture and the use of our activities. We wish the organisers every success for their workshops in August.
To the rest of the world - - please let us know of any similar uses of our ideas.

The problem was that activities and videos mentioned in blog posts before November 2008 were linked to the PBwiki Earthlearningidea website. We have checked all the links on the blog from the first post on 6th May 2007 and all should now go straight to our current Earthlearningidea website.
Our remit at the beginning of the project was that everyone everywhere should have access to our activities without having to pay, subscribe or log-in to anything.
We hope we have solved the problem but please let us know if you are still asked to log-in to access something. You don't need to log-in - just go straight to the website.

A mixture of sand and sugar will separate into its components if poured slowly and evenly into a pile. The process can also be tried with different materials - sand, glass beads, sugar crystals - and the results are clear. Typically, larger grains will have a steeper angle of repose than smaller ones, and they will roll down the slope more energetically. The smaller grains tend to get stuck at the top of the pile, the larger ones at the base—they spontaneously segregate. But things become more complicated. As the different angles of repose of different grains are reached and exceeded, successive avalanches will be made up of different-sized grains. The cascades of smaller grains will stop first, to be then covered by a layer of the larger grains still on the move. The process repeats itself over and over, creating a layered pile. Different (and unpredictable) results can be achieved by varying the size, density, and shape of the grains and therefore their angle of stability or repose.

- what might you see?
- what might you hear?
- what might you taste, smell?
- what might you sense?
- what might you be feeling - scared? - happy? - amazed?

This an easy activity to set up and carry out. It could form part of a lesson about volcanic eruptions and their effects. Is it better to use one source or several in trying to predict an eruption? How do you prepare a response to an eruption in a volcanic area? Please let us know what your pupils think.

It is important to know about these faults as they explain why a rock layer like a coal seam in a mine, may suddenly stop only to be discovered higher or lower on the other side of the fracture in the strata.

In January, I tried the sediment transport investigation "Mighty river in a small gutter; sediments on the move", using some planks covered in a plastic sheet to set up the "stream table". You only need washed sand, some small pebbles of gravel and a bottle of water. You can see erosion, transportation and deposition very clearly.
I also tried the thought experiment "Flood through a window: what would you see, how would you feel?", looking through the window of the classroom. Some answers were very curious!
The students were 15 years old and enjoyed both activities very much. I shall use them again in the future.
The Earthlearningidea team is very pleased to receive comments and photos such as this. Please do send yours to us.
