I can present a mechanism design and justify it using sketches, calculations, prototype evidence, and test data.
POE Unit 1 • Lesson 1.18
Final Design Review and Reflection
Focus question: How can a final design review defend a mechanism using calculations, prototype evidence, and test data?

Lesson Targets
What You Will Be Able to Do
Final design review presentation and reflection
The final review links the mission problem, design decisions, calculations, prototype revisions, and test data into a defensible engineering argument.
Activity Flow
How the Lesson Moves
This page highlights the lesson elements you need for practice, evidence, and submission.
1. Build the evidence story
Organize the problem, requirements, concept decision, calculations, prototype, tests, and revisions.
2. Defend the final design
Use visuals and data to support claims and acknowledge remaining limitations.
3. Reflect on the process
Identify the most important learning, tradeoff, and next improvement.
Lesson Interactive
Organize a Defensible Final Design Review
Reorder the sections so the presentation tells a coherent engineering story from mission need to tested conclusion.
Review Goal
The audience should be able to trace why the team chose the mechanism, how calculations informed it, what happened during prototyping, and whether the final evidence supports the claim.
Reorder the Story
- Present final test data and criterion results.
- Define the mission problem, criteria, and constraints.
- Explain revisions made from evidence.
- Show concept alternatives and the justified decision.
- State the final claim, limitations, and next improvement.
- Show prototype construction and observed issues.
- Present ratio, work, power, or circuit calculations.
Move the sections into an evidence-based engineering narrative.
Today’s Work
Main Deliverable
Final Design Review Presentation and Reflection
Present the rover mechanism and submit a concise engineering reflection.
- Include requirements, concept rationale, calculations, prototype evidence, test data, and final performance claims.
- Explain one successful decision, one limitation, and the next evidence-based revision.

Mission Debrief
One way today’s lesson connects to an aerospace mechanism or VEX rover system.
One type of evidence you could use to support a design decision.
One question you still have about mechanisms, energy, power, or the Unit 1 challenge.
