AB: Life of the Aquifer is a program to improve Earth Science education in local public high schools. Geologic awareness among the local population is low because southeastern N.C. are on the Coastal Plain where rocks are not visible. This has made instruction in Earth Science, now required in North Carolina high schools, difficult. Our approach is to use groundwater, source of local public water, as a theme to organize instruction in geology. More than 70% of the student population in Robeson County, a rural low-wealth area, is from groups under- represented in the geosciences (46% Native American and 31% African American). Linking basic concepts in geology to groundwater is a way to show how geology is real and affects society. Our project engages teachers and students in active inquiry of the functioning of local aquifers from recharge to groundwater production. Although data on water levels in the Black Creek aquifer have been collected, there has been little formal investigation because serious problems with groundwater have not been noted to date. Nonetheless, the hydraulic head of Black Creek Aquifer wells has been declining. We started by improving skills of local Earth Science teachers, because most have had no formal education in geology. The teachers attended workshops on basic geology, groundwater, and exercises based on local groundwater data. The workshops also included field trips to outcrops exposing the local aquifer, 100 km away in South Carolina. We also showed teachers how each topic addresses Competency Goals in the Standard Course of Study. By using our instructional modules, the teachers assist their students to develop spatial reasoning skills by analyzing maps. Student geologic knowledge is increased by learning how the components of a groundwater system form as a result of geologic processes and collecting data from the Internet on changes in groundwater systems over time. Our remaining implementation activity is installation of wells to sample the surficial water table on the grounds of each participating school. When this is completed, students will be able to do their own monitoring of fluctuations in the water table as it responds to high frequency drivers such as variation in rainfall. The project builds knowledge about groundwater to educate students, teachers and the community before irreversible problems can arise with this important environmental resource.
