Integrated Science – Tuesday
Today students in the Integrated Science Residential Program continued their exploration of the properties and possibilities of water. In the morning, students began investigating current topics in water, ecosystems, and conservation for their week-long research projects. They also were introduced to osmosis: the movement of water through a membrane. In the afternoon, students applied that knowledge to a real-world scenario by emulating Red Cross workers in a dialysis-simulation lab. They soaked semipermeable tubes of mystery “dialysis solution” in “blood” – water dyed with red food coloring – and measured changes in mass and color between the different tubes. Kidneys clean waste products from your blood, of course, as part of the job of maintaining a delicate balance of water in the body, and Dr. Randall discussed with students how these processes in the human body mirror the cycling of water through ecosystems.
