In this investigation, students will measure production of CO2 from surface water and consider the role of surface waters in the global carbon cycle and climate change. They will gather data on using Vernier CO2 sensors. This lesson presents a wonderful opportunity for student-designed experiments.
This is a good lesson to get students thinking about the complexity of the systems involved in providing our society with energy, the consequences of energy use and efficiency. Students are encouraged to explore the data sets on their own, ask their own questions about energy use and present their findings to each other.
Have you ever wondered how polar scientists do it? How do they really know if the planet is losing vast quantities of ice anyway? You can use pictures from satellites to monitor the surface from year to year, but the vast majority of ice is hidden from view, buried beneath the surface in some of the most inhospitable and
In this one hour webinar PolarTREC teacher Tim Spuck explains his work with the NASA IceBridge Project, the largest airborne survey of Earth's polar ice ever conducted.
Students will use marshmallows to simulate toxins in the environment. Concentrations of these toxins will be modeled and calculated as they bioaccumulate up the food chain. Methylmercury and POPs are substances that bioaccumulate in the Arctic food chain. OASIS scientists studied these in Barrow, Alaska. (See Ocean Atmosphere Sea Ice and Snow (OASIS) Project at www.polartrec.com)
Students will discover how a simple action such as turning on a television will lead to toxins in our food supply. Many of these toxins concentrate in the Arctic because of long-range transport of pollutants in the atmosphere. Scientists in the OASIS project (http://www.polartrec.com/ocean-atmosphere-sea-ice-and-snowpack-interactions) study these pollutants in the Arctic. Students will learn about actions that they can take to
