This resource is a 12-minute video that presents an overview of soil science. The composition of soils and the processes which produce healthy fertile soil are discussed, as well as what is needed for plant growth and sustainable agriculture. Finally, some examples of the ecosystem services performed by soil, including acting as a carbon sink, are discussed. This resource does not shy away from jargon, but does an excellent job explaining terminology and making the topic approachable. This resource is recommended for teaching.
Science and Engineering
ESS2: Earth’s Systems
MS-ESS2-2 Construct an explanation based on evidence for how geoscience processes have changed Earth’s surface at varying time and spatial scales.
HS-ESS2-2 Analyze geoscience data to make the claim that one change to Earth’s surface can create feedbacks that cause changes to other Earth systems.
ESS3: Earth and Human Activity
MS-ESS3-1 Construct a scientific explanation based on evidence for how the uneven distributions of Earth’s mineral, energy, and groundwater resources are the result of past and current geoscience processes.
LS2: Ecosystems: Interactions, Energy, and Dynamics
MS-LS2-3 Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.
HS-LS2-3 Construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions.
