How do we model Carbon Dioxide in the Classroom?
Look at what you know and what you think you know from your Know/Need To Know board then begin to form a visual model that answers your problem statement about the effect of carbon dioxide levels in the classroom. Lay out the visual model using STELLA software. The variables that affect the CO2 levels will be the converters and stocks and the interactions will be the flows. The mathematical relationship that develops in the STELLA model should be reflected in your hypothesis and experimental design. Go back and forth between your model and your experimental design until you are satisfied with your hypothesis and experimental design and you feel that you will be testing what you think is happening in your model.
