Activity

Sedimentary sand art

Summary: 
Make layered sand art from different sand colours, with a discussion of sedimentary rocks.
Science content (2016 curriculum): 
Earth/Space: Rock cycle, Earth Materials, Natural resources (5)
Science topic (2005 curriculum connection): 
Earth and Space Science: Earth's Crust (grade 7)
Lessons activity is in: 
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:
