After studying the trees and the land, students have begun focusing on the water. We have begun collecting data, studying and exploring the stream. The question was asked, “How do the plants and trees on the land relate to the water in the stream?” After studying both the land and the water, we will look at how they are connected.
To start, we began with a discussion. Some of the questions asked were: Where does this water come from? What is in the water? What lives in the water? To follow, students played a game of tag where each student was something that could be in the water, or a water quality parameter. Students were oxygen, nitrate, nitrite, heavy metals, algae and ammonia. The students would play a specific game of tag for a few rounds and then we would see who, or what, was left. This game allows students to see that water quality is based on what is found in the water.
We then split up into 3 groups and studied three different parts of the stream, upstream, midstream and downstream. We caught aquatic insects and we will use the species of insect caught to deduct or analyze the water quality. Some insects live only in poor water quality, while some need excellent water quality to survive. If we analyze the insects we catch, it can give us an idea of our overall water quality.
