Exploring Waste Water Management for High School Teachers and Homeschooling Parents

Introduction:

Teaching waste water management to high school students can be challenging, but with hands-on activities, we can make it engaging and interactive. In this blog post, we will explore two exciting DIY projects suitable for high school teachers and homeschooling parents who want to teach waste water management effectively.

Activity 1: Building a Model Septic Tank

Objective:

To understand the functioning of a septic tank and its role in wastewater treatment

Materials Required:

2 beakers
Plastic pipes (cut into appropriate lengths)
Water
Syringe
Food coloring (optional)

Procedure:

Begin by explaining the purpose and working of a septic tank to the students.
Instruct them to place the two beakers side by side, representing the different compartments of a septic tank.
Connect the beakers using the plastic pipes, creating an inlet for waste water and an outlet for treated water.
Fill one of the beakers with water mixed with food coloring to represent sewage.
Show students how to use the syringe to pump the sewage from one beaker to the other through the pipes.
Observe how the sewage settles in one compartment while the water is gradually treated and flows out through the outlet.
Discuss the importance of regular maintenance and pumping of septic tanks to prevent environmental pollution.

Activity 2: Creating a Water Overflow Sensor

Objective:

To demonstrate the need for water management and develop an understanding of water conservation techniques

Materials Required:

Container (such as a plastic bowl or a glass jar)
Buzzer circuit (available at electronics stores or online)
Water
Jumper wires

Procedure:

Explain the concept of water overflow and its impact on water conservation.
Guide the students in assembling the buzzer circuit using the provided instructions.
Place the buzzer circuit in the container and ensure it is secure.
Fill the container with water, leaving some space for overflow.
Connect the buzzer circuit to the container using jumper wires.
As the water level rises and reaches the circuit, the buzzer will sound, indicating an overflow situation.
Discuss the importance of water conservation practices and the significance of managing waste water effectively.
