This experiment will help students to understand the role of plants in filtering the water moving through a watershed. Students will discover that soil and plants have something of a dual role in this process and, depending on whether materials are dissolved or suspended in the water, soils and plant roots can remove some or all of this material as the water moves down through soil. They also learn that most suspended materials will adhere to the soil and these may then be broken down and used as food by the plants. This experiment is a very simplified way to show whether plants will take up certain kinds of materials from water moving relatively quickly through their root systems.
