The Student Enabled Network of Sensors for the Environment using Innovative Technology (SENSE IT) project will integrate science, technology, pre-engineering and mathematics (STEM) skills into a robust interdisciplinary curricula and teacher development effort by teaching 3,000 high school students to design, build, test, deploy and interpret their own environmental sensors. SENSE IT will span three distinct residential regions in New York's Hudson and St. Lawrence River valleys (Potsdam, Troy and Beacon), as well as a diverse socioeconomic and racial spectrum. SENSE IT will reach at least 60 teachers in the region, providing 120 hours of professional development, in-class support and necessary equipment, while directly increasing awareness of STEM career opportunities for students and teachers.
