During our June 24th water testing session, Dr. Emilly Obuya–Sage College professor of chemistry and long-time NATURE Lab contributor–joined our fellows, mentors, and visiting artist Ipi Fernandez for a conversation on water justice and the scientific method. We talked through the stages of observation and being curious about our environments, forming a hypothesis, or educated guess, collecting and interpreting data, and how that data can be interpreted and used for positive change. We also visited the 123rd boat launch in Lansingburgh to sample water in the rain. Of course sewage contamination levels came back high on Sunday because rain contributes to combined sewer overflows.
