Using Mathematics and Computational Thinking

Scale, Proportion, and Quantity

Students know:

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.

Students are able to:

Graph the given data (using standard units) about the amount of salt water and the amount of fresh water in each of the following reservoirs, as well as in all the reservoirs combined, to address a scientific question:
- Oceans.
- Lakes.
- Rivers.
- Glaciers.
- Ground water.
- Polar ice caps.
Use the graphs of the relative amounts of total salt water and total fresh water in each of the reservoirs to describe that:
- The majority of water on Earth is found in the oceans.
- Most of the Earth's fresh water is stored in glaciers or underground.
- A small fraction of fresh water is found in lakes, rivers, wetlands, and the atmosphere.
