Learn about the processes performed at a water treatment plant and the reasons for these processes. Students perform several of the procedures that occur in a water treatment plant on "polluted" water on a smaller scale. They examine the changes in the water after each treatment step and observe the physical characteristics of water, such as clarity, color, and odor and how they are affected from the beginning of the treatment process until the end.

Great for small groups or for students who are working at home!
Students develop knowledge of the processes performed at a water treatment plant and learn the reasons for each process. They perform, on a small-scale, several of the procedures that occur in a water treatment plant on "polluted" water. They examine the changes in the water after each treatment step is performed. Students also observe physical characteristics of water, such as clarity, color, and odor and how they are affected from the beginning of the treatment process until the end. Contains enough materials for 5 groups and includes teacher's manual and student study guide.

This kit addresses the following Next Generation Science Standards*:
