Scientific paper
Present studies are being conducted as a part of the outreach project entitled Geomagnetic Event Observation Network by Students (GEONS) to share excitement of the THEMIS (Time History of Events and Macro scale Interactions during Substorm) mission launched during February, 2007. The goal of this mission is to investigate the causality of events that lead to the explosive release of energy (derived from the Sun) stored in the Earth's magnetic field. The visible manifestation of the energy release is Aurora Borealis observed in the Northern hemisphere of the Earth. Inherent to understanding the root-cause of formation of spectacular aurora is the interaction between the Earth's magnetic field and the solar wind charged particles. To achieve this ambitious objective in a high school classroom, students conducted activities using the magnetic field of bar magnets, electromagnets, electromagnetic induction, and Lenz's Law. Following the fundamental understanding of these concepts, students acquired the necessary vocabulary and explored the various components of the interaction between the Earth's magnetic field and the solar wind charged particles. They were also familiarized with the general format in which THEMIS spacecraft data is displayed. In this presentation, we will address student's misconceptions, their struggle to make connections before they can appreciate "Big Idea" in terms of its components. Discussion will highlight the relationship between student understanding of new ideas and how these ideas connect with their prior knowledge.
