Learning Targets
- Fabricate components using the approved design and safe procedures.
- Check fit with the provided rocket throughout the build.
- Document changes from the approved plan and explain why they were necessary.
IED Unit 0 • Lesson 0.8
Prototype Build
Focus Question: How do engineers turn a plan into a prototype while documenting changes?
Mission Briefing
Today’s Plan
Every task advances the same Rocket Launch Pad Design Challenge.
Learning Targets
Success Looks Like…
The prototype is complete, the rocket can be installed and removed, and the build record explains any important deviations from the final drawing.
Project connection: Your work today becomes evidence used in the next stage of the Engineering Design Process.
Prototype
Build the approved design
Fabrication is part of the engineering process. If reality forces a change, document it.

Day 1
Fabricate the primary structure
- Review certification status and the approved cutting layout.
- Measure and cut foam-board components.
- Prepare craft sticks, straws, and string as required by the plan.
- Assemble the base and primary supports.
- Use the provided rocket for controlled fit checks.
- Add major braces and allow hot-glue joints to cool before loading.
- Photograph or sketch the build status before cleanup.
Day 2
Complete, brace, and inspect
- Complete the rocket-support interface.
- Add planned bracing and structural connections.
- Confirm the rocket installs and removes without damage.
- Check the 12 in × 12 in footprint and 12 in pad-height limits.
- Check that the structure stands on its own.
- Complete workmanship and safety cleanup.
Build Record
Do not quietly change the design
| Original Plan | What Changed? | Why? | Evidence / Observation |
|---|---|---|---|
| Describe the planned feature. | Describe the change. | Explain the reason. | Fit issue, material behavior, measurement, etc. |
Engineering rule: A change made during fabrication is still a design decision. Record it.
