5-ESS2-2 Earth’s Systems
|
Students who demonstrate understanding can: Describe and graph the amounts and percentages of water and fresh water in various reservoirs to provide evidence about the distribution of water on Earth. |
Clarification Statement: N/A
|
Assessment Boundary: Assessment is limited to oceans, lakes, rivers, glaciers, ground water, and polar ice caps, and does not include the atmosphere. Only a tiny fraction is in streams, lakes, wetlands, and the atmosphere.

Disciplinary Core Ideas
|
Scale, Proportion, and Quantity:
- Standard units are used to measure and describe physical quantities such as weight and volume.
|
Using Mathematics and Computational Thinking:
- Mathematical and computational thinking in 3–5 builds on K–2 experiences and progresses to extending quantitative measurements to a variety of physical properties and using computation and mathematics to analyze data and compare alternative design solutions.
- Describe and graph quantities such as area and volume to address scientific questions.
|
The Roles of Water in Earth’s Surface Processes:
- Nearly all of Earth’s available water is in the ocean.
- Most fresh water is in glaciers or underground; only a tiny fraction is in streams, lakes, wetlands, and the atmosphere.
