5-ESS2-2 Graph amounts of salt water and fresh water on Earth

Describe and graph the amounts of salt water and fresh water in various reservoirs to provide evidence about the distribution of water on Earth.

Assessment boundary: Assessment is limited to oceans, lakes, rivers, glaciers, ground water, and polar ice caps, and does not include the atmosphere.

Why water teaches this standard well

This is the strongest science-meets-math water standard in elementary school: students graph why about 97 percent of Earth's water is salty ocean and less than 1 percent is accessible fresh water. That single graph explains in one lesson why treatment plants, conservation, and careful water management matter.

Materials tagged with this code are written to the full standard and assessment boundary, and each carries a written note explaining the alignment. See how we review materials.
