Humans are creative. They try to solve problems in original ways. For example, some scientists are thinking of ways to decrease the amount of greenhouse gases in the air. Other scientists are thinking of ways to limit the amount of sun that reaches Earth so that the Earth won’t get so warm. Like most ideas, there are pros (good
Textbooks say that carbon dioxide is a greenhouse gas and can make earth's climate hotter. Try this lab to see if carbon dioxide gas can really act like a greenhouse.
Objectives
Students should be able to make a hypothesis, perform an experiment, analyze data and write a conclusion based on the evidence from their experiment.
Teacher Betsy Wilkening and researchers publish an article in the Journal of Geophysical Research stemming from their work on the PolarTREC OASIS project.
This PolarConnect event was conducted with PolarTREC teacher Claude Larson, and members of the research team that she worked with on the Prehistoric Human Response to Climate Change 2010 project in Kamchatka, Russia.
This PolarConnect event was held on 16 August 2010, and included Keri Rodgers and members of the ITEX research team studying tundra plant changes in response to a warming climate in the arctic. The research team worked in Barrow and Atqasuk, Alaska. This event was conducted in English and Spanish, and was the first bilingual PolarConnect event.
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
