Focuses on the why:
It emphasizes that the project's purpose is not just to build a model, but to use the engineering process to gain a deeper, more meaningful comprehension of a biological system.
Encourages deeper inquiry:
The question is open-ended and requires exploring the relationship between different scientific principles, which is a key element of effective STEM projects.
Promotes higher-order thinking:
Answering this requires analysis and evaluation, not just a simple recall of facts. It prompts reflection on how engineered systems compare to man made ones.
