Milligan University of South Florida, Tampa, FL, USA. [email protected] Abstract. In mathematics education there has been voluminous consideration of "alternative" approaches to deliver content. At every stage of formal education, motivating students to learn mathematics is accomplished by making the material relevant to them. In the undergraduate calculus sequence, concepts of mensuration are made “real” when students actively use the relevant processes. While textbooks generally offer examples and exercises for students, these are more effective when students have personal motivation via Action Learning, or what are often called “Projects.” The article presented here is an example of what might be composed by the student as an application project. It demonstrates that, in addition to the mathematics, there is an abundance of relevant discussion connected to a topic to gain the writer’s (and hopefully the reader’s, as well) interest. Projects are reviewed by course instructors and subject area supervisors. The one student plus two professionals requirement has merit supported by this example. For starters, the instructor need not be (in this case) a professional astronomer and the astronomers (subject area advisors) need not know all the mathematical details behind each equation presented in a project write-up. The student can draw from these two real sources for motivation, and there’s “action” for all participants. It is not difficult to sense that a project student will likely retain the information learned for a longer period and be ready to synthesize the concepts with other real-world situations as they may arise.

    JOURNAL OF GEOPHYSICAL RESEARCH, VOL. ???, XXXX, DOI:10.1029/, Ocean Worlds in the Outer Solar System F. Nimmo1 and R.T. Pappalardo2 Abstract. Many outer solar system bodies are thought to harbor liquid water oceans beneath their ice shells. This article first reviews how such oceans are detected. We then discuss how they are maintained, when they formed, and what the oceans’ likely char- acteristics are. We focus in particular on Europa, Ganymede, Callisto, Titan and Ence- ladus, bodies for which there is direct evidence of subsurface oceans. We also consider candidate ocean worlds such as Pluto and Triton. 1. Introduction consequences of these oceans; and the extent to which they might be habitable.
