How is farming a system? What are the inputs (fertilizer, pesticide, seed) and outputs (crop yield, emissions, runoff)? What impact does soil as a storage have on the consequences of these inputs and outputs?
Systems thinking, applied in business and environmental science, examines the interconnected parts of a whole, categorized as inputs (external additions), outputs (productions), storages (reserves for future use), and flows (movement of matter and energy). In agriculture, inputs like seeds, fertilizers, and water interact within the soil system, influencing crop production. Soil composition—sand, silt, clay—along with nutrient levels (Nitrogen, Phosphorus, Potassium) and pH, affects plant growth. Mismanagement, particularly over-fertilization, can lead to cultural eutrophication, creating "dead zones" in water bodies by depleting oxygen, crucial for aquatic life.

Meet Jim Love and Sheila Downey from Becks Hybrids as they take you on a virtual field trip to showcase how precision technology in agriculture helps farmers make better decisions to improve yield and increase profitability. Learn what drones can do and how they are used! See how data is collected to help inform farmers' decisions on crop growth and potential inputs as they discuss how technology is changing agriculture.
What are GMOs? How is genetic modification done? Can genetic modification help …
What are GMOs? How is genetic modification done? Can genetic modification help to reduce the impact of human activities on natural systems? Plasmids are DNA that determine the traits of bacteria. Transform bacteria by inserting a plasmid and examine the results of this transformation. Compare this process to the techniques currently used in food production.

How does the production of corn affect water quality? How is water quality tested?
Corn production's impact on water quality has improved due to best management practices, reducing sediment and nutrient losses significantly. Modern agriculture uses genetically modified crops and efficient water infiltration methods, alongside USDA programs and the 4 Rs nutrient strategy, to lessen environmental impact. Water quality is assessed through chemical tests measuring properties like dissolved oxygen and nutrients, essential for aquatic life. Biological assessments, based on vertebrate and macroinvertebrate diversity, indicate water health, reflecting the ecosystem's chemical and physical condition. Riparian zone management, affecting stream structure and temperature, plays a crucial role in maintaining water quality, highlighting the interconnectedness of agricultural practices and aquatic ecosystems.

Prior to this lesson learners engage in the Arcadia Earth app’s Keep the Great Lakes GREAT section to build their understanding of the Great Lakes and its importance to all animals that call this area home, including humans. Next learners explore food chains with a hands-on activity, Linking the Chain. Students then synthesize what they know about the Great Lakes, food chains and how human behaviors can affect both.
Estimated time required: 1 class period.
Technology required for this lesson: Tablet or Smartphone.
