Water Quantity
Students remove measured amounts of water from a five-gallon bucket, simulating the amount of fresh water available on earth.

Groups of learners work on a single Great Lake and connecting waterway and then come together as a class to construct a simple three-dimensional model of the Great Lakes. Individual groups also
present their Great Lake and connecting waterway information.
By creating a map of the rivers flowing into your Great Lake, learn how rivers form a watershed.
How much water does each Great Lake hold? Use this lesson as a demonstration or a classroom lesson to create visual representations of the Great Lakes, Lake Baikal, and the relationships between surface area, retention time and pollution effects.
Two of the most important characteristics of ocean water are its temperature and salinity.
Together they help govern the density of seawater, which is a major factor controlling the ocean’s
vertical movements and layered circulation.
Students use a simple model to discover that air moving over water causes the surface of the water
to move horizontally. In writing and in a discussion, students relate this concept to surface currents in
the ocean and the Great Lakes.
Objectives:
Groups of learners work on a single Great Lake and connecting waterway and then come together as a class to construct a simple three dimensional model of the Great Lakes. Individual groups also present their Great Lake and connecting waterway information.
After participating in this activity, learners will be able to:
