✓Lesson Snapshot
Student Objective
I can identify independent variables, dependent variables, controls, and repeated trials in an aerospace test.
Main Activity
Plan a controlled test for a glider, projectile, rover, payload drop, or launch system.
Deliverable
Controlled test plan draft
Tools / Materials
Notebook, measurement tools, timer, data sheet, graph paper
1ProblemUnderstand the challenge and why it matters.
Mission tests can produce misleading results if variables are not controlled. A fair test requires a clear plan before students collect data.
2ConceptLearn the engineering idea or skill.
A controlled experiment changes one independent variable, measures a dependent variable, and keeps important conditions constant. Repeated trials help reveal variation and improve confidence.
3ApplyUse the skill in a guided task.
Write a test question for an aerospace motion system and identify the independent variable, dependent variable, controlled variables, and number of trials.
4DocumentRecord your evidence and decisions.
Record a test plan with a data table that is ready for repeated measurements.
5ReviewCheck quality and identify your next step.
Your plan should make it possible for another team to repeat the same test under similar conditions.
