Artist Alexander Calder made a tiny set of mobiles which fitted into a cigar box. Not all artists have been trained to be artists. Artist Helen Chadwick made sculpture from melted chocolate - a bubbling fountain which filled the gallery with the smell of cocoa. Christo and his wife Jeanne Claude wrapped islands in Greater Miami, Florida. They also wrapped whole buildings and bridges - sometimes spending years planning their sculptures and involving teams of people to help create them.
People often think of sculpture as being solid, but sculpture is also about space .
Try making a three-dimensional drawing by twisting a piece of wire into a shape. Alexander Calder made a whole circus, with acrobats, dancers, lion tamers - all from wire. Pupils gave a grey school chair a completely different personality by covering it in fur fabric and tinsel. Groups of children had a room each, to turn into sculpture.
