Filter design & materials
Materials: [Add the filtration materials used.]
Construction: [Describe the filter container and how the layers or components were arranged.]
FRESHMAN-YEAR PROJECT / GRADE 9
Water
Filtration.
My first-year Engineering CTE project centered on water filtration. This case file frames the engineering question and leaves the specific build details ready to fill from the original project record.

01 / THE ENGINEERING QUESTION
From a broad goal
to a testable system.
Filtration design connects a physical process to measurable choices: what enters the system, what the filter is meant to retain, and how the output is evaluated. The project record identifies water filtration as its focus; the exact build and test conditions belong in the notes below.

02 / PROJECT RECORD
Details that make
the build yours.
Use the original project materials to complete these fields. Keeping the design, method, and observations specific makes the case study accurate and useful.
Testing method
Starting condition: [Describe the water sample or starting point.]
Comparison: [Explain what you observed or measured across each trial.]
What the evidence showed
Observation: [Add your documented result and any limits.]
Next revision: [Name one change you would test next.]

The available source confirms the project title and freshman-year placement. The diagram above is conceptual; replace the bracketed fields with your original build details before presenting them as project findings.
03 / ENGINEERING × FINANCE
Performance has
a cost curve.
A filtration design can be compared by both function and resource use. This is a framework for analyzing the project—not a claim that the original work included a measured budget.
A SIMPLE EVALUATION MODEL
FILTER COST÷WATER PROCESSED→COST PER UNIT
When comparing alternatives, the useful question is not only “Which sample looks clearest?” It is also “How much material, time, and repeat testing did that result require?” A more complete record could compare the cost of each material setup with a consistent output measure, then consider whether a small improvement justifies extra cost or slower flow. That same tradeoff appears in product development and finance: allocate limited resources to the version that delivers the strongest verified result.
