I can distinguish weak observations from repeatable evidence in an aerospace performance investigation.
POE Unit 4 • Lesson 4.1
Unit Launch: Mission Performance and Test Data
Focus question: How can repeated test data turn a single mission result into a defensible engineering decision?

Lesson Targets
What You Will Be Able to Do
Mission performance evidence map
The evidence chain uses repeated controlled trials, readable data displays, and a claim limited to the results.
Activity Flow
How the Lesson Moves
Each step builds the data, motion, or testing reasoning required for today’s deliverable.
1. Compare evidence
Rank one trial, repeated trials, and controlled repeated trials by decision value.
2. Trace the argument
Connect measurement, graph, statistic, and claim.
3. Define readiness
State what evidence would justify continuing, revising, or retesting.
Lesson Interactive
Build a Defensible Evidence Chain
Apply the lesson concept to a mission-performance scenario. Use the feedback to correct your reasoning before completing the main deliverable.
Mission Claim
“The rover can reliably stop inside the landing zone.” Select the evidence features needed before the team can defend that claim.
Reminder: A dramatic single success may be useful for troubleshooting, but it is not reliability evidence.
Choose the combination that supports a repeatable, readable, and appropriately limited claim.
Today’s Work
Main Deliverable
Mission performance evidence map
Create one focused engineering artifact that demonstrates today’s learning.
- Map the path from mission question to measurement, analysis, and decision.
- Identify one limitation that prevents the evidence from supporting a stronger claim.
Exit Ticket
Mission Debrief
State the most important data-analysis or motion concept from today in your own words.
Name the measurement, calculation, graph feature, or test decision that supports your conclusion.
Identify one uncertainty, limitation, or next test that would strengthen the evidence.
