I am presenting a project on the greenhouse effect for eighth grade 
students.  I have planted plants in a closed system and am introducing 
carbon dioxide using vinegar and baking soda.  I am trying to see how much 
of the carbon dioxide the plants will remove from the air.  I know I can 
withdraw some air and mix in limewater to prove the presence of carbon 
dioxide but I do not know how to get an accurate measurement of the carbon 
dioxide levels.  I have read other questions and responses on the same 
topic but cannot find a detailed answer.
