Making a River System Model

Comment 0

A river system is a number of interconnected rivers that form because of the natural movement of water down a slope. It consists of the main river and different smaller rivers that drain into bodies of water such as a lake or the ocean. In this simple science activity, the students learned how natural river systems are formed through the use of a simple soil model.

The patterns formed are similar to those found in nature.

In this picture, a student is making the soil more compact by pushing on it with his hands.

In this picture, a student is making the soil more compact by pushing on it with his hands. The purpose is so that the model somewhat resembles the natural compactness of soils found near rivers.
