Make your own rock

Try our latest activity - 'Make your own rock; investigating how loose sediment may be stuck together to form a 'rock'' To become hard rocks, most sediments need to be cemented together. This idea can be tested with a variety of 'cements'. Pupils can demonstrate how 'rocks' are made by compacting and cementing loose sand. This activity is very popular in the UK - let us know how it is received in other countries.
