The Lego (TM) method of showing weathering, erosion, transportation and deposition

Today's new ELI is another in our ELI Early years series:
'The Lego^TM method of showing weathering, erosion, transportation and deposition: using Lego^TM bricks to demonstrate sedimentary processes'

The activity for young children demonstrates how different rocks break down at different rates. The sedimentary processes of erosion, transportation and deposition are also explored. It is fun to do but, beware, lots of help will be needed to collect the Lego^TM bricks at the end!
Many more ideas for teaching Earth science to young children can be found in ELI Early years.
