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
In this lesson students research scientific field expeditions and learn what it is like working in the field. Students are able to ask questions of the research team as part of their project. Students then share what they have learned with their classmates.
Objective
1. Students understand what really goes on in the field during a scientific study.
2
An important science skill that needs to be developed is asking significant questions that advance knowledge. This activity helps students to understand the difference between significant and trivial questions.
Objective
Students should be able to distinguish between significant questions that advance knowledge and trivial questions.
Procedure
1. Have the students define significant question and trivial questions in a
