They are a series of two-week sessions during the summer when young people can come to practice different kinds of art all day. The younger children take a broad view, trying out many different types of visual art, music, and theater, while the older students may choose to experiment with many types of expression or concentrate on a specific form.
So at your age, if you wanted to try a little bit of everything just for fun and self-expression, you could. Alternately, you could decide that you wanted to spend two weeks, for example, improving your clay sculpture technique with an instructor who specializes in that.
Sessions begin in June, going two weeks on, one week off through the end of August, and campers may take as many sessions as they like.
