Following our Story of the World chapter on the Wars of the Greeks, we did "stone" sculpture with soap. The Greeks did so well making statues and friezes that when their towns and cities were taken over, their hard work was taken as bounty.
The kids also worked hard and enjoyed "sculpting", but the next day I found Avery with Jasper's project crumbled on the floor.
One of the benefits of working with stone i suppose.
