This is a simulation, not a quiz. You answer by trying things and watching what happens.
Our question
What controlled comparison will help you compare paper-flight designs using repeated, fair tests rather than one lucky flight?
Getting the simulation ready…
1Change the design
2Say what will happen, then test it
3Finish: say what you found
What counts as evidence
Select the measured comparison that directly addresses the prediction.
Name the changed condition, cite one result, and connect it to this goal: Compare paper-flight designs using repeated, fair tests rather than one lucky flight.
Your criteria, constraints, measured failure, iteration, and tradeoff defense become inspectable engineering evidence.
First Launch: predicted what should change before this action: Set thrust and payload parameters.
