Quarry through the window

'Quarry through the window - what would you see, what would you not see?' This is our latest Earthlearningidea - click here to view the activity in English. It can also be found in Spanish in the 'Resources and Environment' category (Recursos y Medio Ambiente) - click here.
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.
Ask your pupils to try this activity and send us their work. We will publish the best.
