Innovating Science- Small Group Learning: Water Treatment and Filtration

Students will develop a knowledge of the processes performed at a water treatment plant and understand the reasons for each process. They will perform, on a small-scale, several of the procedures that occur in a water treatment plant on “polluted” water. They will examine the changes in the water after each treatment step is performed. They will also observe physical characteristics of water, such as clarity, color, odor, and how they are affected from the beginning of the treatment process until the end.
This kit contains enough material for 5 groups. Teacher's Manual and Student Study Guide copymasters are included.
