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

The Oklahoma Academic Standards for Science (2026) outcome 5.ESS2.2 (Earth and Space Sciences) for Grade 5 says: “Describe and graph amounts of saltwater and freshwater in various reservoirs to provide evidence about the distribution of water on Earth.” This Fieldbook unit teaches it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson. Official wording: Oklahoma Academic Standards for Science (2026).

The Water Cycle, Start to Finish Grades 3–6

A water-drop journey game around eight stations of the room, a 100-square model of where all of Earth's water really is, from USGS data, and a sealed bag of water on a sunny window that shows the Sun driving the whole cycle. Two of the three lessons need nothing but printed sheets.

  • Where is all of Earth's water? 45–60 min

    Teams shade two 100-square grids from real USGS data to show how much of Earth's water is salty, frozen, underground or in lakes and rivers, then the whole class becomes a human model of all the water on Earth. Students graph the amounts and explain why fresh, liquid water is so precious.
