Question

which step is part of the engineering design process but is not part of a scientific investigation?
a. performing tests
b. solving a problem
c. using math and measurements
d. identifying criteria and constraints

Explanation:

Scientific investigation focuses on exploring natural phenomena to build knowledge, while engineering design aims to create solutions to human problems. Performing tests, using math/measurements, and addressing problems are common to both. However, identifying criteria (desired features of the solution) and constraints (limits like cost or materials) is unique to engineering design, as scientific investigations do not require defining such solution-specific parameters.

Answer:

D. Identifying criteria and constraints
