Abstract
In introductory-geology courses, the combined difficulty and importance of Bowen's reaction series justify that it be taught with unconventional zeal. One such approach involves first singing Bowen's list of minerals to one's students and then casting the students as atoms of Si, Fe, Mg, Ca, Na, and K, according to their gender. Crystallization and melting are demonstrated by selectively having students sit down or stand up depending on the elements they represent. These methods achieve two fundamental learning objectives. The student will learn to: 1) list the order in which minerals crystallize from a cooling silicate melt and 2) explain how rocks of different compositions can form from the same parent magma by fractional crystallization, or from the same parent rock by partial melting.
