KNOWLEDGE

Terminology

Specific details
and elements

– Students will recall the three major types of hazardous material

– Students will recall the local reservoirs that supply water to their water treatment plant

– Students will recognize different types of commonly used acids & bases

– Students will recognize the importance of killing giardia in drinking water

– Students will identify & illustrate the materials used in filters in a water treatment plant

– Students will illustrate the size of micron by comparing it with the thickness of human hair

– Students will identify and interpret an illustration of the hydrologic cycle (h. c.) and understand it as a system

 

– Students will use the appropriate metric & standard English units as appropriate during water treatment tests

– Students will divide the total storage capacity by seasonal usage to determine backup storage

– Students will find the similarities between the filters designed in their classroom and those at the water treatment plant

– Students will analyze the sources of water for our use and consumption

– Students will predict the groundwater situation when there is an excess or deficiency in precipitation based on their understanding of the h. c.

 

– Students will generate a list of jobs available for students' personal career choices using Monster’s website

B.
PROCEDURAL
KNOWLEDGE

Subject-specific skills and algorithms

Subject-specific techniques and methods

– Students will identify the
processes used to kill cryptosporidiumduring water treatment

– Students will identify experimentally the
pH of commonly used substances

– Students will classify different materials used in filters in terms of their function(s)



– Students will measure flow rate using a graduated cylinder and stop-watch

– Students will use the appropriate metric & standard English units to calculate flow rates of their test-filters
– Students will organize the different materials used in filters at water treatment plants

– Students will demonstrate knowledge of appropriate steps they might take as a plant operator during emergencies
  – Students will design their set up for filters with four materials
C.
CONCEPTUAL
KNOWLEDGE

Classifications and categories

Principles and generalizations

Theories, models, and structures

Specific details
and elements
 

– Students will compare and contrast their filters (design and materials) with those at the water treatment plant

– Students will paraphrase what they learned from the “Filtration Project

– Students will predict the settling order of the different layers (based on densities) in water treatment plant filters

– Students will use appropriate tools (graduated cylinder, stop-watch, pH paper, probes, laser) to test the quality of their filtered water

– Students will use their knowledge of living things and apply it to reservoirs that supply water to water treatment plants

– Students will distinguish between fiters used in water treatment plants and their class designs

– Student will test the performance of their filters in terms of the four tests

– Student will test their filters and rate their performance in terms of the four tests

– Students will generate appropriate designs for filters using only 4 materials

– Students will construct an improved design of filters after testing out their initial designs

D.
META-
COGNITIVE

KNOWLEDGE

Strategic knowledge

Cognitive tasks, including appropriate contextual and conditional knowledge

Self-knowledge
 

– Students will explain their design of test-filters in terms of systems, trade-offs, constraints, & feedback

– Students will summarize their learning experience in the "Filtration Project "

– Students will use their a) knowledge and understanding of water contaminants and b) material properties to design their test-filters

– Students will deconstruct the Benchmarks from “failure, lines of reasoning, and interacting parts” using examples from their own experimentation

– Students will judge their own and their peers work based on five criteria: design, creativity, explanation, cost efficiency, and test-endurance
