Sedimentary rock

We made some tasty sedimentary rock which had lots of layers of soil, sand, rock, pebbles and fossils. We used broken up Oreo’s for bits of rock, crumbled digestives for sand, melted chocolate for soil, smarties and sultanas for pebbles and mini marshmallows and mixed fruit for shells and fossils. This was all squashed together and left for a few million years (10 mins in the fridge) and we then had some delicious sedimentary rock!
