Urgent! About investigatory project on CO2 sequestration! Please?

Question

I know CO2 Sequestration has those forest stuffs, electric plants and emissions something blah blah. I know there's a simpler way on how could we show the people how CO2 sequestration works!

Chemistry geniuses, could you please suggest a simple investigatory project that can prove that CO2 sequestration works and exists in a very very simple way?

Thank you very very much! I need serious answers please! =(

Answer 1

Perhaps you could show a seed from a tree, a small branch from the same tree and a piece of charcoal (partially burned branch from fireplace?) and ashes from a completely burned branch.  The seed grows to a large plant using solar energy and photosynthesis that takes in carbon dioxide from the atmosphere (sequestering it) combining it with hydrogen from water to make hydrocarbons while releasing excess oxygen to the atmosphere.  Charcoal remains when all the water and hydrogen is driven from the wood and ash remains when the carbon is burned returning carbon dioxide to the atmosphere.  You can make a poster showing the cycle (in steps) and display the samples.
