STEM Engineering Principles in Education 4

Question 1

In engineering education, 'biomimicry' refers to designing solutions that:

Accepted Answer

Imitate strategies found in nature to solve human problems

Answer

Biomimicry applies natural strategies — such as the lotus leaf's water repellency — as inspiration for innovative human-made designs.

Question 2

A student team disagrees on which design to pursue. Which professional engineering practice should the teacher encourage them to use to resolve the conflict?

Accepted Answer

Use a decision matrix to evaluate options against weighted criteria

Answer

A decision matrix provides an objective, criteria-based framework for comparing alternatives and reaching a data-driven team consensus.

Question 3

Which principle does the engineering concept of 'redundancy' address in safety-critical systems?

Accepted Answer

Providing backup systems so a single failure does not cause total system failure

Answer

Redundancy ensures reliability by duplicating critical components so the system continues functioning if one component fails.

Question 4

When teaching 'human-centered design,' a STEM teacher emphasizes that the process should begin with:

Accepted Answer

Empathizing with and understanding the end user's needs

Answer

Human-centered design starts with deep user empathy to ensure the final solution genuinely addresses real human needs and contexts.

Question 5

Which engineering principle explains why a drinking straw becomes structurally stronger when bent into an arch shape?

Accepted Answer

Load redistribution through compression along the curve

Answer

Arches redirect loads into compressive forces along the curve, allowing thin materials to support greater weight than in a flat configuration.
