The natural urge to play with materials is very evident in sculpture. Expanding on this natural urge, teachers have a great opportunity to introduce a wonderful range of materials and techniques to children that expand the two-dimensional offerings of most children's art programs. In this subject, students use art appreciation of public sculptures as the stimulus for working in ceramics, metal and wire, aerated concrete, plaster and a range of natural and fabricated materials to explore carving and modelling techniques.
