This document summarizes a conference on using serious games and virtual worlds for science education. It discusses how today's students are accustomed to gaming and need interactive, immersive learning experiences. Serious games promote motivation, challenge, active learning and problem solving. The conference featured a virtual island created in OpenSim for role playing games and simulations of volcanic areas. Students solve problems and interact to explore concepts like tsunamis, rocks and debrief their experiences. Principles for good game-based learning emphasize simplified contexts, active learning, reflection and extensive practice in an engaging environment.
