First of all, we take a look at various ways of measuring water pollution and among them, we include experiment for student to know about the water pollution by using indicator organisms. Next, we examine how some elements in our daily life affect on water and provide class with systematically technological and engineering solution. With this text book, we let the student recognize environmental problem and seek for the solution about it. Therefore, it helps student to connect with stream of thought.
