Numerous studies have shown that one of the best ways to draw students into geoscience programs is to expose them and their
teachers to research projects designed to investigate issues relevant to their lives and communities. To be most effective,
involvement in these projects should begin at the pre-college level and continue throughout their college career.
Recognizing the importance of genuine research experiences, the Department of Geology at California State University,
Bakersfield (CSUB), with support from the National Science Foundation's {\it Opportunities for Enhancing Diversity in the
Geosciences} program, provides research participation opportunities for teachers and students from the Bakersfield City
School District and the Kern High School District. Both districts have a high percentage of low-income and minority students
that normally would not consider a degree or career in the geosciences.
The project centers around a four-week summer research program and follow-up activities during the school year. The research
investigates the climate history of the southern San Joaquin Valley as well as the frequency of flooding in the valley. Many
teachers and students are familiar with periodic flooding from personal experience and are aware of the larger issue of
climate change in the past and present from news reports. Thus, they can directly relate to the relevance of the research.
The project draws on the faculty's expertise in paleoclimatology and geochemistry and takes advantage of CSUB's existing
research facilities.
Sediments in the dry lake basins of Buena Vista Lake and Kern Lake preserve a record of the regional climate history and
flooding of the Kern River and its tributaries. In the first year of the project, 6 teachers and 10 high school students
worked with CSUB faculty and students. Three cores from the lake basins were collected. The cores were analyzed using
established geophysical, geochemical, lithological, and micropaleontological techniques. The analyses of the sediment
samples range from simple tasks such as core descriptions or total organic carbon analysis to complex procedures such as the
separation, identification, and chemical analysis of ostracode shells. Thus, the participants can find tasks appropriate to
their diverse backgrounds and experience. CSUB students served as mentors and role models for high school students.
Surveys conducted before and after the summer program indicate that knowledge of climate change and local geology of both
teachers and students increased. Student's attitudes towards the geosciences and possible geoscience careers improved.
