After exploring the science of energy and energy conversion, students will evaluate some environmental impacts of hog farming and explore technologies that minimize negative human impact by creating biogas energy from animal waste.
Students explore the process of fermentation in the creation of ethanol and observe the role enzymes play in the fermentation of starch.
Students will use the scientific method to learn about the growth properties of algae and how algae production may be a possible solution to address the global energy crisis. Students will utilize the engineering design process to apply their knowledge about algae growth to create a bioreactor for algae production and discover if biofuel can be made from algae.
In this lesson students will describe the domestic food supply chain and identify the use and types of energy involved in the growth, harvest, processing, transportation, and marketing of an agricultural commodity.
