When it rains, much of the water drains directly in the ground. But why? Try this experiment and draw your own conclusions.
| Grade | Discipline | Core Idea |
|---|---|---|
| 3-5 | ESS2.A: Earth materials and systems |
Four major Earth systems interact. Rainfall helps to shape the land and affects the types of living things found in a region. Water, ice, wind, organisms, and gravity break rocks, soils, and sediments into smaller pieces and move them around. |
| 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. |
| 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 | 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. |
| 9-12 | ESS2.A: Earth materials and systems |
Feedback effects exist within and among Earth's systems. |
| 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. |
