Grade Discipline Core Idea
6-8 ESS3.C: Human impacts on Earth systems Human activities have altered the biosphere, sometimes damaging it, although changes to environments can have different impacts for different living things. Activities and technologies can be engineered to reduce people's impacts on Earth.
9-12 ESS3.C: Human impacts on Earth systems Sustainability of human societies and the biodiversity that supports them requires responsible management of natural resources, including the development of technologies.
6-8 LS2.C: Ecosystem dynamics, functioning, and resilience N/A
9-12 LS2.C: Ecosystem dynamics, functioning, and resilience If a biological or physical disturbance to an ecosystem occurs, including one induced by human activity, the ecosystem may return to its more or less original state or become a very different ecosystem, depending on the complex set of interactions within the ecosystem.
6-8 LS4.D: Biodiversity and humans Changes in biodiversity can influence humans' resources and ecosystem services they rely on.
9-12 LS4.D: Biodiversity and humans Biodiversity is increased by formation of new species and reduced by extinction. Humans depend on biodiversity but also have adverse impacts on it. Sustaining biodiversity is essential to supporting life on Earth.
