WHERE DOES YOUR USED WATER GO?
INTRODUCTION
Students and their parents should know how wastewater gets to
a treatment facility, and what type of treatment the wastewater
receives there. The following activity and investigation panel
are designed to examine how used water gets to a treatment facility
and the treatment process or processes utilized in your community.
Do the activity first, then ask the students to answer the questions
addressed by the investigation panel.
ACTIVITY
OBJECTIVE
To demonstrate what happens to wastewater and the importance of
treatment facilities to a community.
MATERIALS REQUIRED
- One piece of wood, rope, or a strip of paper, approximately
2.4 meters long.
- Two pieces of wood, rope, or strips of paper approximately
0.6 meter long.
- One piece of wood, rope, or strip of paper approximately 0.7
meter long.
- Shredded newspaper.
- Cardboard box, any size.
TEACHER PREPARATION
- Place a copy of this poster on the wall where the students
can see it.
- Set up materials for the activity as shown in the following
diagram.
The 2.4-meters-long
object represents the main underground sewer pipe. Place the cardboard box at
one end of the "main sewer
pipe" to represent the wastewater-treatment facility. At
the other end of the "main sewer pipe," place two 0.6-meter-long
objects to represent underground pipes coming from buildings where
water is being used (homes, schools, restaurants, factories).
Place the 0.7-meter-long object perpendicular to the middle of
the "main sewer pipe." This object represents underground
pipes coming from homes recently constructed in the community.
