There is a plausible explanation for how carbon dioxide molecules could interact with water molecules thereby forming a solution where the carbon dioxide is the solute and water is the solvent (as it usually is). The weak inter-molecular attractive forces rely on the polarity of the water molecule and the high density of electrons at either end of the
When a bottle or can of carbonated beverage is opened the carbon dioxide is allowed gas to come out of solution. This is because there is a pressure differential between the carbon dioxide in the liquid and carbon dioxide in the air. The pressure in the liquid is higher than the pressure in the air so the carbon dioxide moves
This activity is 4 of 4 in a series that exposes students to the concepts of and work done by the HERMYs Project (Historical Ecology and Risk Management: Youth Sustainability):
1. A Narrative Pantomime
2. Environmental Risk Assessment
3. Risk Hazard Identification
4. Local and Traditional Knowledge & Risk

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
Students will undertake a long term project to evaluate the effectiveness of different local forecasters, match the forecast with the actual weather and analyze which forecaster is best.
Objective
Students will compare the accuracy of different weather forecasts. Students will compile and analyze their own data gaining a better understanding of the challenges involved in weather forecasting
This activity is designed to make a connection between a group of scientists and the students.
Objective
Students will learn that scientists are people too.
Preparation
The teacher will need to contact a group of scientists to make sure they would like to participate in the project and to explain to them the goals of the
