✓Lesson Snapshot
Student Objective
I can perform non-destructive tests and use observations to infer useful material properties.
Main Activity
Run simple tests for hardness, flexibility, continuity, ferrous response, surface condition, and dimensional consistency.
Deliverable
Non-destructive material test results
Tools / Materials
Material samples, magnet, multimeter if available, calipers, hardness/flexure test setup
1ProblemUnderstand the challenge and why it matters.
Engineers often need information about a material without destroying the part. Non-destructive tests help identify properties before final use.
2ConceptLearn the engineering idea or skill.
Non-destructive tests may check dimensions, hardness, flexibility, surface finish, magnetism, electrical continuity, or visible defects while leaving the sample usable.
3ApplyUse the skill in a guided task.
Rotate through material test stations and record evidence for each sample. Use observations to infer likely material properties and applications.
4DocumentRecord your evidence and decisions.
Complete a non-destructive test table and identify which material seems best suited for the Unit 2 project.
5ReviewCheck quality and identify your next step.
Observation is evidence only when it is specific, recorded clearly, and connected to a design decision.
