Engineering Worksheet: Materials
Engineer's tip (Match the property to the job): Ask: what must it do — keep water out, bend, let light through, carry current or stay cool? Metals and graphite conduct electricity; rubber, plastic, dry wood, glass, pottery and cloth insulate. Pick the material whose main property fits the job.
