Water Testing in Middle School Lab

Middle School Students tested the water in the Charles River for pH, dissolved oxygen level, and temperature. They then compared the results to the water study we conducted during our visit to Walden Pond in October and water from Crawford Notch in New Hampshire in September.

Additionally, they began to explore photosynthesis. Students were introduced to the photosynthesis reaction equation, 6 CO₂ + 6 H₂O + Energy –> C₆H₁₂O₆ + 6 O₂, and are currently exploring the role of water and carbon dioxide. They placed cabbage leaves in water dyed with food coloring to observe how plants “drink” water.
