To complement their study of explorers, the Primaries made clay Viking ships. We started by rolling a flat slab of clay with a rolling pin and then cutting out the bottom of the boat. Next, we rolled coils of clay to build up the walls. Finally, students could choose to add a dragon head to the ship and shields. We painted a fabric sail while the clay projects dried. After these were fired in the kiln, we painted them with watercolor paints and attached the sails. These were sprayed with a varnish to seal the paint.
