Wastewater Treatment PlanningLearning Standards
STATE GOAL 1: Read with understanding and fluency.
STANDARD A: Apply word analysis and vocabulary skills to comprehend selections.BENCHMARK1.A.3a: Apply knowledge of word origins and derivations to comprehend words used in specific content areas (e.g., scientific, political, literary, mathematical).
GOAL 12: Understand the fundamental concepts, principles and interconnections of the life, physical and earth/space sciences.
STANDARD C: Know and apply concepts that describe properties of matter and energy and the interactions between them.BENCHMARK 12.C.3a: Explain interactions of energy with matter including changes of state and conservation of mass and energy. Process diagram-Explain how all the material coming into the system must also go out in some form. Analyze the changes taking place with solids, liquids and gasses.
STANDARD E: Know and apply concepts that describe the features and processes of the Earth and its resources.BENCHMARK 12.E.3c: Evaluate the biodegradability of renewable and nonrenewable natural resources. KWL- What types of solids can be broken down and reused?
STATE GOAL 13: Understand the relationships among science, technology and society in historical and contemporary contexts.
Standard B. Know and apply concepts that describe the interaction between science, technology and society.Benchmark 13.B.3c: Describe how occupations use scientific and technological knowledge and skills. KWL-What do you have to know to be able to work here?Benchmark 13.B.3d: Analyze the interaction of resource acquisition, technological development and ecosystem impact. KWL-How do you know what can and can’t be reused? Where does the waste end up?
Benchmark 13.B.3e: Identify advantages and disadvantages of natural resource conservation and management programs. KWL-What would happen if we didn’t treat the water? Are there other ways to handle wastewater?
Benchmark 13.B.3f: Apply classroom-developed criteria to determine the effects of policies on local science and technology issues. KWL-Are there rules for what type of waste or chemicals can be put into the water? What happens if people break the rules? How do you know when the water is clean enough? How do you know what to do with all the solids, liquids and gasses?

Wastewater Treatment Process Cards
Wastewater is held for several hours – solid particles sink. The wastewater is disinfected to
kill harmful pathogens.
Debris is sent to a landfill.The wastewater is slowed down to allow sand, gravel and other
heavy material to settle.
Solids reused as fertilizer, incinerated or sent to landfill.
Large objects such as sticks, cans and rocks are removed.
