Students work individually on centers of their choice. Each center has three levels: a novice level to introduce a subject, an apprentice level to broaden or delve deeper into a subject, and a master level to provide for student synthesis and evaluation. Some examples of centers include:  Computer Art and Computer Music, Castles, Landscape Design, Polyominoes, Architectural Design, Creative Writing, Bridge Design, and What's Up In Space? There are over thirty-five different centers from which the students may choose.
