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 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
Students use data and pictures of a destroyed wind sensor, to develop a theory of what happened to the station. They then develop a plan to make sure the station is not destroyed again.
Objective
Students will be able to use data to develop a reasonable hypothesis.
