To apply students' savvy internet skills in the science classroom--as well as capture their interest in science and investigation, and provide opportunities for authentic research--introduce them to real-time data from ocean-observing systems. Students can use data from these ocean-observing systems to discover the winds and waves from storms or to explore currents and predict marine-organism distribution. The four web-based student activities presented in this article bring the world of high-tech instruments and real-time data information to the classroom.
