Materials
  • Sand colours, in separate tubes
  • Small bottles or containers. I have used old cuvettes.
  • Small squares of paper, with a crease in, to use to pour the sand into the container
  • Tape to seal containers
  • Sedimentary rocks with clear coloured layers
Procedure

Students make thin layers of sand in different colours. Tap the container between each layer so that they settle densely.
Once the container is completely full, seal the top with tape, to prevent the sand from shaking around and the colours mixing.

Discuss how sedimentary rocks are formed, and look at real sedimentary rocks to see the layered patterns they make.

Notes

Included in rock study lesson, but better placed in a sedimentary rock cycle lesson.
