Make your own sedimentary rocks with 'fossils'

A very good Early years activity is 'Rock builder; simulating the formation of fossiliferous sedimentary rocks'.

This activity simulates the formation of fossiliferous sedimentary rocks using a variety of sediments and shells in a plastic bottle, with filler acting as cement to ‘glue’ the grains together.
