In the dead of the night on June 21, 2000, several refrigerated trucks drove into London on a strange mission. They were carrying 14 enormous snowballs, each weighing a ton or two, which had to be gently deposited at carefully chosen locations by 6 a.m. so that they would begin melting during the morning rush hour. Inside each snowball, artist Andy Goldsworthy had buried something interesting, such as sheep's wool, horse chestnuts, pine cones, barbed wire, or beech branches. He hoped that people would take pleasure in watching this filling slowly emerge as the snowballs melted over the next few days. Most people, finding a giant snowball on a city street in the middle of summer, could not resist patting it gently. Others picked curiously at the emerging debris. Sadly, one of the snowballs, which was filled with the winged seeds of an ash tree, was deliberately destroyed by an enraged passerby. Perhaps he was an art critic.
- How did the energy stored in the snowball change as it melted?
- Design your own artwork based upon a physical change. What is the change that occurs? What does your artwork look like? What might it help people to understand? Write a paragraph about your artwork, and include a diagram or a drawing of it.
