    manipulated was the fuel to oxygen ratio and the variable that we observed was how efficiently the fuel burned in each of the mixtures. The efficiency of the combustion depended on the fuel to oxygen ratio. If mixture was fuel lean the combustion reaction would produce less soot and smoke. If the mixture was fuel rich‚ an incomplete combustion reaction occurred and it produced plenty of soot and smoke. The controlled variable was the amount of water in the test tube. If there was more water in one
