Art provides students a way to visually represent their scientific knowledge and at the same time helps teachers assess student understanding. Examining a drawing allows teachers to scrutinize students' mental model of a science concept. Science can be described as a continuing process of discovering the order and recurring patterns in nature; therefore, science that involves action and the act of creating artistic representations models the very nature of the scientific enterprise. Curriculum integration of art and science makes the connection not only between the disciplines but also more importantly between students and the concepts of science. In this article, the author emphasizes the important role that art plays in the science classroom, and presents examples of science/art activities. (Contains 2 figures.)
