The New Millennium Observatory (NeMO) is a seafloor observatory off the coast of Oregon, which studies the relationships between submarine volcanic events and the chemistry and distribution of hydrothermal vents and the biologic communities that depend on them. The research activities at NeMO provide an extraordinary educational opportunity, both from the daily reports from expeditions at sea and from creative learning materials based on NeMO results. This curriculum is based on real events and real data: the 1998 eruption at Axial Volcano and the rumbleometer instrument that was stuck in the new lava flow. The activities for the classroom are modeled on how scientists actually investigated this event. This curriculum is intended for middle and high school students in earth science and marine science classes and includes advice for presentation and additional background information that could be incorporated into the lessons. It is supported by the National Science Foundation, Oregon Sea Grant, and Oregon State University.
