Soils around the world vary in color, texture, structure, and chemical, physical, and biological composition. Slides and activities on soil orders
| Grade | Discipline | Core Idea |
|---|---|---|
| 6-8 | ESS2.A: Earth materials and systems |
Energy flows and matter cycles within and among Earth's systems, including the sun and Earth's interior as primary energy sources. Plate tectonics is one result of these processes. |
| 6-8 | ESS2.E: Biogeology |
[Content found in LS4.A and LS4.D] |
| 6-8 | ESS3.A: Natural resources |
Humans depend on Earth's land, ocean, atmosphere, and biosphere for different resources, many of which are limited or not renewable. Resources are distributed unevenly around the planet as a result of past geologic processes. |
| 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. |
| 6-8 | LS4.D: Biodiversity and humans |
Changes in biodiversity can influence humans' resources and ecosystem services they rely on. |
| 9-12 | ESS2.A: Earth materials and systems |
Feedback effects exist within and among Earth's systems. |
| 9-12 | ESS2.E: Biogeology |
The biosphere and Earth's other systems have many interconnections that cause a continual co-evolution of Earth's surface and life on it. |
| 9-12 | ESS3.A: Natural resources |
Resource availability has guided the development of human society and use of natural resources has associated costs, risks, and benefits. |
| 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. |
| 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. |
