As part of Ms. Orbuch's environmental monitoring program at SLVHS, students monitor phytoplankton at the SC Harbor bi-weekly.  In addition to collecting data for their research questions, their samples also contribute to CDPH's Phytoplankton Monitoring Program.  Keep an eye out for these young scientists every spring at the high school science fairs!

Current students: Halie Davis, Ian Gallagher, and Quinn Lydon
