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.
Students compare the components of beef and plant-based burgers by determining the production and processing methods of each product; evaluate the ingredients and nutritional differences between beef and plant-based products; and discuss different points of view in the agricultural industry concerning plant-based proteins and traditional beef. This lesson covers a socioscientific issue and aims to provide students with tools to evaluate science within the context of social and economic points of view.
Students will view the 2014 film Farmland, a documentary spotlighting six farmers and ranchers in the United States. The film portrays the business and lifestyle of a variety of farmers and ranchers. Perspectives on topics such as bioengineered (GMO) crops, animal welfare, organic and conventional farming practices, farm size, farming stereotypes, and more are presented.
Students explore the impact of fertilizer on algae growth, soil erosion, and agricultural soil and water conservation practices.
Students explore the carbon cycle and evaluate the carbon footprint of cattle. Using critical thinking skills, students will use the Claim, Evidence, and Reasoning model to determine the effect of cows’ methane production on the environment and investigate the extent cattle contribute to climate change.
Students explore the carbon cycle, evaluate natural and human-induced activities that drive the carbon cycle, and discover climate smart agricultural practices that can be used to produce our food.
Students observe soil ecosystems to investigate how human impact affects the biodiversity of soils using the Simpson's Index of Diversity. Then, students conduct an investigation using field corn to determine how the introduction of nitrogen fertilizers impact soil microorganisms and biodiversity.
Evaluate the agricultural advances of the Green Revolution, discover the contributions of Norman Borlaug, and discuss the impacts of this era from an economic, social, political, and environmental perspective by watching the 2020 PBS film, The Man Who Tried to Feed the World.
Students will discover the connection between climate and our food supply as they answer the question, "Where does it grow?" They will also explore the consequences of climate change on our food supply and discover how advances in science can help farmers adapt to climate change.
In this lesson, students will take on the role of a nitrogen molecule and experience how various forms of nitrogen cycle through the environment. Students will be able to identify and differentiate between atoms, molecules, and compounds.
