Students evaluate the growth of human populations across time, analyze graphic data to make predictions about future population growth, research country statistics to evaluate demographic transition, and participate in a simulation of a village reliant on subsistence farming. Students begin to develop a sense for the Earth's carrying capacity and how humans have impacted it.
Students examine different types of soil that have been mixed with water and allowed to settle. Next, they work with a soil model to investigate its components (sand, silt, and clay) and learn how the properties of these components affect the passage or retention of water through the soil and the amount of air in the soil.
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.
Discover how technological advances and economic forces influence the size of farms in the United States. Evaluate the pros and cons of large-scale agriculture for the production of our food, fuel and fiber and identify the similarities and differences in commercial vs subsistence farming.
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.
Explore modern livestock farming practices and the ecological footprint of meat, milk, and egg production. Evaluate the contributions of the livestock industry and weigh the challenges related to environmental and economic sustainability of animal-source foods in comparison to plant-source foods.
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 explore the origins of food, describe how food waste affects natural resources and the environment, and identify potential solutions to mitigate food waste’s carbon footprint.
Explore concepts of sustainability by evaluating the water footprint (WF) of food. Students are introduced to irrigation practices throughout the world, consumptive and non-consumptive water use, and investigate the water requirements for various food crops.
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.
Virtual Farm Trips® offers free, engaging, live, and on-demand virtual field trips that connect audiences directly with farmers on their actual farms. Unlike pre-recorded and highly edited virtual field trips, these experiences are interactive and unscripted, allowing participants to engage in real-time conversations with farmers in their fields, equipment, and barns. With this approach, no two Virtual Farm Trips are ever the same. For educators and families, the platform offers a variety of live and on-demand trips suitable for different age groups and interests.
