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

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.
Students will learn the basics of calorimetry, energetics and respiration as they pertain to their own bodies and to those of other species, including arctic animals.
Objective
Students will learn about respiration, calorimetry and the energetic needs of various species including their own. Students will compare food intake to daily energy consumption and consider the consequences of
Students will conduct quantitative and qualitative observations on living organisms. By recording careful measurements, making and testing various hypotheses, on super mealworms, students will gain some understanding of how wildlife researchers conduct their studies.
Objective
Students learn to take measurements on living organisms and use those measurements to consider the health of the organisms.
