I can analyze prototype results, prioritize a revision, and present a supported final structural claim.
POE Unit 2 • Lesson 2.18
Data Analysis, Iteration, and Final Design Review
Focus question: How should structural test data drive revision and final design claims?

Lesson Targets
What You Will Be Able to Do
Final structural design review
The review uses calculated and measured evidence, explains the revision, and states both achievement and remaining limitation.
Activity Flow
How the Lesson Moves
Each step builds the structural reasoning needed for the lesson deliverable.
1. Analyze the data
Compare load capacity, mass, deformation, and efficiency with the criteria.
2. Prioritize a revision
Address the failure location or largest performance gap with a targeted change.
3. Defend the final design
Present the problem, decisions, evidence, revision, result, and limitation in a logical order.
Lesson Interactive
Analyze the Prototype and Build the Design-Review Story
Calculate structural efficiency, select the strongest result, and organize the evidence into a defensible final review.
Prototype Results
| Prototype | Mass | Verified load | Max deflection |
|---|---|---|---|
| A | 120 g | 600 N | 7 mm |
| B | 150 g | 900 N | 5 mm |
| C | 105 g | 525 N | 11 mm |
Organize the Final Review
- Final performance claim and remaining limitation
- Targeted revision based on the evidence
- Load-test data, deformation, and failure observations
- Prototype geometry, mass, and build evidence
- Load path, calculations, and material reasoning
- Selected structural concept and why it was chosen
- Mission need and measurable criteria
Calculate load ÷ mass, consider deformation and criteria, then tell the story from need through evidence to claim.
Today’s Work
Main Deliverable
Final Structural Design Review
Prepare the final evidence-based review of the payload support structure.
- Include the design decision, calculations, prototype data, failure or deformation evidence, and revision.
- State a final claim tied to the criteria and identify one limitation or next improvement.
