A series of 3D cut out paper models that show the different forms of sand dunes including:

Parabolic Dunes

Barchan Dunes

Longitudinal Dunes

Dune Migration model



All students need is a printer, scissors, and glue to make a 3-D model.


These models were developed by Tau Rho Alpha and myself as part of resources for Geoscience Australia and then The Geological Society fo America – both now giving them away for free.
