I had my 8th grade create bowls and plates for their clay project this last quarter. The ceramic works were stunning when finished. They used coils and spheres to create the designs. I asked students to put feet on their projects. They good do as the student did below, create 3 or 4 feet at the bottom or they could add a coil wrapped around into a circle to raise the work off the surface a bit. I really stressed that they needed to make these 'thick as a double stuffed Oreo cookie' and almost all made it through both firings.
