Everything that we eat has nutrients. Nutrients get into the soil many different ways: from decomposed animal waste and dead plants, the atmosphere, weathering of rocks and bacteria conversions. Slides and activities
Next Generation Science Standards
| Grade | Discipline | Core Idea |
|---|---|---|
| 3-5 | ESS3.A: Natural resources |
Energy and fuels humans use are derived from natural sources and their use affects the environment. Some resources are renewable over time, others are not. |
| 3-5 | ESS3.C: Human impacts on Earth systems |
Societal activities have had major effects on the land, ocean, atmosphere, and even outer space. Societal activities can also help protect Earth's resources and environments. |
| 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. |
| 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. |
