What is ethanol and how is it made?
The students in the fifth grade class were making ethanol through the process of fermentation. Ethanol is a fuel that comes from plants so it is called a biofuel, and it can be used like gasoline. The students measured water, corn syrup, and yeast; they mixed all their materials in a water bottle and placed a balloon over the top of the bottle. After about thirty minutes, the balloon filled up! Through discussing and investigating, the students were introduced to biofuels by studying ethanol.
