Learning Targets
- Begin constructing the prototype from the approved plan.
- Document changes made during construction.
- Identify early build problems and possible fixes.
IED Unit 5 • Lesson 5.9
Prototype Build Day 1: Structure and Core Function
Focus question: How do engineers move from a planned design to a physical prototype while documenting changes along the way?
Mission Briefing
Today’s Plan
Use this page with the lesson presentation, your engineering notebook, and the tools or evidence assigned for Build the Prototype Structure and Core Function.
Success Looks Like
You can begin building the prototype structure or core function while documenting changes and issues.

Opening Prompt
How do engineers move from a planned design to a physical prototype while documenting changes along the way?
Connect your response to the decision, evidence, or quality standard required for Build the Prototype Structure and Core Function.
Reveal: useful engineering move
This lesson is ready to move forward when the evidence meets this standard: The prototype demonstrates the intended basic function and all unplanned changes are documented.
Core Skill
What We Are Practicing
Build days should follow the plan while still recording necessary changes.
Structure and core function come before decoration or polish.
Unexpected problems become evidence when documented clearly.
Your Task
Build the Prototype Structure and Core Function
Construct the first physical version of the design while documenting changes from the approved plan.
- Complete material, tool, and safety checks.
- Build the structural base or primary form.
- Install or create the core function.
- Record progress, deviations, and one issue for the next build session.
Quality check: The prototype demonstrates the intended basic function and all unplanned changes are documented.
Lesson Interactive
Plan Prototype Build Day 1
Sequence the work so the team establishes a safe structure and core function while preserving evidence of changes.
- Record any deviation from the fabrication plan
- Verify parts, tools, and safety requirements
- Inspect the build and secure loose parts before stopping
- Assemble the primary structure and datum interfaces
- Confirm the core mechanical function
Build-day standard
Do not hide changes made during fabrication. Record them so the model, prototype, and final documentation can be reconciled.
Start with verification and structure. Finish with documentation and inspection.
What You Will Submit
Prototype Build Day 1 Evidence
Submission standard: The prototype demonstrates the intended basic function and all unplanned changes are documented.
