✓Lesson Snapshot
Student Objective
I can compare metals, polymers, ceramics, composites, and wood/paper materials using properties important to aerospace design.
Main Activity
Evaluate material samples and connect density, strength, stiffness, cost, manufacturability, and sustainability to design decisions.
Deliverable
Aerospace material selection chart
Tools / Materials
Material samples, balance, calipers or ruler, notebook
1ProblemUnderstand the challenge and why it matters.
A material that works well in one application may fail or be wasteful in another. Aerospace engineers must choose materials based on the mission and constraints.
2ConceptLearn the engineering idea or skill.
Material families include metals, polymers, ceramics, composites, and natural/wood-based materials. Engineers compare density, stiffness, strength, toughness, thermal behavior, cost, manufacturing process, and sustainability.
3ApplyUse the skill in a guided task.
Evaluate several materials and rank them for a payload support structure. Explain why the top material choice fits the design problem.
4DocumentRecord your evidence and decisions.
Complete a material selection chart that includes property evidence and a final recommendation.
5ReviewCheck quality and identify your next step.
A material recommendation must connect to the actual function of the part, not just a general statement like “strong.”
