How to see how much Carbon Dioxide is emitted from burning a substance such as wood or ethanol?

I'm going to do an Open Ended Investigation and I can calculate how much CO2 is emitted by using chemical equations and whatnot, but I actually need an experiment for the assessment. So is there an experiment (that can be done at home/school) to see how much CO2 is emitted from burning wood or ethanol?

If you bubble your combustion products through a solution of sodium hydroxide, it will convert the carbon dioxide into sodium carbonate.  If you can carefully remove the solvent and dry the sample, you can calculate how much CO2 was absorbed by weighing.  It won't be easy without specialized equipment, but you might be able to make something work.  It is very dangerous to burn things in a closed container, however, and you should talk with your instructor about how to do this experiment safely.
