This article describes an Earth Systems approach that was developed to prepare preservice elementary school teachers in understanding science content and pedagogy with emphases in technology and mathematics. This approach, developed at the University of New Orleans, uses Lake Ponchartrain as the unifying theme for four courses in which students learn both scientific content and process. The authors note that many children decide if they like or dislike science by middle school and that improvements in science teaching in the middle grades are imperative, and that improving elementary science education is especially important in regions where significant portions of the student body are from groups traditionally under-represented in science. Surveying and field-testing results suggest that participants in these classes are likely to apply this approach to science teaching in their own classrooms.
