Students utilize different components (enzymes, yeast, feed stocks, and water) to produce ethanol and carbon dioxide through the process of fermentation. Students will develop a model of fermentation and explain how ethanol is made to answer the focus question "How can fermentation produce a renewable fuel source?" Students will develop experimental models to generate data in order to construct explanations about the relationships between the components of the fermentation process and to predict how those relationships can be manipulated to produce carbon dioxide. Students will design solutions to make the fermentation process as efficient as possible and generate the maximum amount of ethanol in a small bag environment Attendees will participate in hands-on activities centered around biofuel. Participants are going to prepare and compare different amounts of fermentation occurring in four different mixtures which will allow observations of production rates. A second activity focuses on a way to make a qualitative or quantitative explanation regarding the relationship between feed stock and glucose availability for ethanol production. Participants will deconstruct a model of starch to examine enzyme and starch reactions to determine how starches change into smaller molecules. Three additional hands-on activities that can be included in your classroom curriculum will be discussed.
Nourish the Future is a national education initiative developed by science teachers for science teachers to connect students to modern agriculture and provide sound science based resources that meet teacher and student needs in the classroom.
