Biofuels: Investigating Ethanol Production and Combustion, Developed by SEPUP (#39S)
This activity includes three major parts:
• Investigation 1 - a demonstration of the fermentation of corn and cane sugar, the two food sources used most commonly to produce ethanol, and the distillation of the fermented stillage to produce fuel.
• Investigation 2 - students investigate the energy released by the combustion of ethanol and kerosene and compares the results.
• Investigation 3 - students measure and compare two by-products - CO2 and particulate matter - of the two fuels. Students compare results and discuss the trade-offs of biofuels and fossil fuels as sources of energy.
Modeling and Comparing Fossil Fuel and Biofuel Combustion (#38)
In Part A of this activity, students use Lab-Aids® Molecular Models to build methane, ethanol, and octane molecules then “combust” them with oxygen molecules. “Combusting” the model molecules helps students determine the balanced chemical equations for the combustion reactions and compare the amount of carbon dioxide released when these three fuels are burned. In Part B students use standard bond energies to calculate and compare the amount of energy released during the combustion reactions they modeled in Part A. They are then asked to use their data about the energy released and the CO2 produced to choose which fuel they think is better.
