Final Launch Pad Challenge & Design Review

Focus Question: How can engineers use performance evidence to defend a design?

Mission Briefing

Today’s Plan

Every task advances the same Rocket Launch Pad Design Challenge.

Learning Targets

  • Demonstrate that the final launch pad satisfies the required constraints and qualification tests.
  • Record final measurements, stability data, and observations directly on the Engineering Design Review form.
  • Use evidence from the full project to defend design decisions, explain iteration, and propose a future improvement.

Success Looks Like…

You complete final testing and a two-page Engineering Design Review that uses specific project evidence—not guesses or general statements—to explain how and why the design performed as it did.

Project connection: This is the Communicate stage of the Engineering Design Process. Your final claims should be supported by evidence collected throughout the unit.

Class Flow

  1. Prepare the form: Put your name, period, team members, and date on the Engineering Design Review before testing begins.
  2. Qualify: Complete Part A as your launch pad moves through each required test.
  3. Compete: Record the maximum successful tilt angle and final observations.
  4. Review: Use your earlier sketches, decision matrix, build notes, and test evidence to complete Parts A–E, then submit the two-page form.
Final Qualification

Pass the required tests before entering the competition

DefineResearchImagineSelectDevelopBuildTestImproveCommunicate

Dimensions

12 in × 12 in maximum footprint and 12 in maximum pad height.

Rocket Interface

Provided rocket installs, remains upright, and removes without damage.

Level Stability

60 seconds unsupported.

Required Tilt

10° in four directions for 5 seconds each.

Disturbance

Pass the standardized instructor-controlled disturbance test.

Use the worksheet while you test: Complete the Part A qualification table as each test happens. Record actual measurements, pass/fail results, and short observations. Do not wait until the end of class and try to reconstruct your data from memory.
Competition

Maximum Tilt Challenge

Most Stable Launch Pad

After qualification, increase the test-platform angle in consistent increments until the design can no longer maintain the required stable condition. The design with the highest successful tilt angle wins the stability challenge.

Mass is not part of the competition.

Record the result on Part A

Write your team’s maximum successful tilt angle on the Engineering Design Review form immediately after competition testing. Use the Evidence / Observation column to capture anything that helps explain the result, such as where the structure began to shift, flex, or tip. If multiple teams achieve the same maximum angle, the smaller qualifying footprint is the tie breaker.

Design Review Worksheet

Complete the two-page Engineering Design Review

The worksheet is your written final evidence for the Launch Pad Challenge. Complete it individually unless your instructor directs otherwise.

IED 0.10 Engineering Design Review

Use this form during testing and competition, then finish the analysis and reflection sections before submitting the lesson.

What counts as strong evidence?

  • Measured footprint, height, time, or tilt angle.
  • Pass/fail results from qualification testing.
  • A specific observation of flexing, shifting, joint failure, tipping, or stability.
  • Evidence from your decision matrix, sketches, build record, or engineering change.
  • A before-and-after comparison from testing and improvement.

Page 1 — Final Performance & Iteration

  1. Header: Fill in your name, period, team members, and date.
  2. Part A: Complete the qualification table during testing. Enter actual results and mark Y/N for each required check.
  3. Maximum tilt: Record your highest successful competition angle.
  4. A1–A2: Identify the strongest and weakest parts of the final design and support each answer with evidence.
  5. Part B: Explain why your team selected its concept, describe the most important change made after testing, and evaluate whether the change improved performance.

Page 2 — Engineering Process & Judgment

  1. Part C: Give one specific example from your project for each EDP step: Define, Research, Imagine, Select, Develop, Build, Test, and Improve.
  2. C1: Explain how your team communicated its engineering work using sketches, the decision matrix, build documentation, test records, or the design review.
  3. Part D: Propose one Version 2 improvement, identify the strongest evidence that your design solved the original problem, and explain what the project taught you about engineering design.
  4. Part E: Complete your self-assessment. Leave the teacher scoring boxes blank.
Evidence rule: Avoid answers such as “it worked well” or “we made it stronger.” Name the feature or change, describe what happened, and point to a measurement, test result, observation, or earlier design document that supports your claim.
Engineering Design Process

You completed the full cycle

Define → Research → Imagine → Select → Develop → Build → Test → Improve → Communicate

The point of Unit 0 is not only the launch pad. It is learning how engineers use a process, evidence, and documentation to move from a problem to a defensible solution.
