The sugarcane undergoing fermentation produced a volume of carbon dioxide that was nearly nine times more than the corn, wheat grain and wheat stalk. Wheat grain and corn was nearly doubled that of the wheat stalk and the control (Figure 1). Sugarcane was the leading plant material producing the highest volume of carbon dioxide (mean= 19.9 ± 0.996 mL) while other than the control; the wheat stalk produced the lowest volume of carbon dioxide (mean= 1.33 ± 0.036 mL). As time elapsed, the sugarcane had the highest reaction rate, nearly nine times more than all the other plant materials (Figure 2). Sugarcane ended with the highest reaction rate (mean= 0.99 ± 0.070 mL/min) while wheat stalk had the lowest reaction rate (mean= 0.067 ± 0.0095 mL/min).

Data Analysis
1. The null hypothesis for this experiment was that for all plant materials, the volume of carbon dioxide produced and the rate of carbon dioxide produced would remain constant and unchanged as the time elapsed. The Alternate hypothesis for this experiment was that sugarcane would be the leading producer 2. came from the fact of sugarcane properties which is composed of simple sugars, therefore the yeast being used for fermentation in this experiment would have a faster rate of producing carbon dioxide rather than spending time breaking down complex sugars into simpler sugars. Our prediction was that sugarcane would be the fastest at producing carbon dioxide due to its composure of simple sugars. 3. Our collected data and overall trend of the two figures indicate that our hypothesis is well supported by the data. The volume of carbon dioxide produced over time graph indicates that sugar cane is the leading producer of carbon dioxide and the Rate of Carbon dioxide production at 20 minutes graph indicated that for specifically sugarcane, its rate of production was greatly higher than all the other plant materials. 4. A) Out the four tested plant materials, sugarcane would be...
