'Gold prospectors; panning for ‘gold’ in river sediment'.
This ELI investigates how prospectors use the property of density to search for gold in river sediments.The technique is still actively used across the world where minerals are exploited, on a wide range of scales.
The activity is aimed at ages 5 and upwards but if you are searching for science ideas for younger children, you could explore 'ELI Early years'.
The new ELI today is the second in our Picturing minerals activity, 'Picturing Minerals -2; visualise and draw minerals from a verbal description'.
This could form a useful revision activity, once pupils have studied minerals. Pupils are required to describe what they see accurately so their partner can draw and, hopefully, identify the mineral. It is not always very easy!

The new ELI today is another in our popular 'picturing' series: 'Picturing Minerals-1; visualise and draw minerals from a verbal description'.
This activity enhances pupils’ skills of description and interpretation using photographs of minerals. It could form a useful revision activity - and it is fun!
More ELIs about Minerals can be found in the Earth Materials category.
When we see a rock as a bundle of evidence of how the Earth used to be, we can begin to look for the clues that tell us about its past history, and the past history of the planet. Rocks are natural time capsules. By using the ‘time capsule’ approach you can bring a rock to life in ways that will amaze pupils and adults alike.
The ELI category 'Visualising deep time' has related activities and activities about rocks generally can be found here.
The new ELI today is part 2 of 'Walther’s law of sedimentation – teaching it the Lego TM way: How does a relative fall in sea level affect a vertical sequence of sediments?'
