ENGINEERING DESIGN PROCESS (ITEEA – 12 STEPS)
What EDP step is when engineers clearly state the problem they are trying to solve?
Identify the problem
Motion that moves in a circle is called what type of motion?
Rotary motion
What part of a system is the material or energy that goes into it?
Input
What career designs solutions to solve problems using science and math?
Engineer
Is a wind-up toy powered by a motor or a spring?
Spring
Which step involves sharing many ideas without judging them?
Brainstorming
Motion that moves back and forth along a straight line is called what?
Reciprocating motion
What part of a system describes what happens inside the system?
Process
Human innovation in action that develops systems to solve problems is called what?
Technology
What are models and simulations used for?
To study problems and test solutions
In which step do engineers build a model or sample of their solution?
Create a prototype
Motion that swings back and forth in an arc is called what?
Oscillating motion
What part of a system is the final result or product?
Output
What is the difference between engineering and technology?
Engineering is the process; technology is the result
What simple machine is used in a toy arm with a pivot point?
Lever
A team tested their prototype and it failed to meet the criteria. What TWO steps of the EDP should they return to, and why?
Test & evaluate, then revise/improve (or brainstorm/select approach) because feedback shows changes are needed.
A windshield wiper swings back and forth. Identify the motion type and explain why it fits that category.
Oscillating motion because it moves back and forth in an arc.
In a hand dryer system, what would most likely happen if the feedback component failed? Explain your reasoning.
The dryer may not shut off or adjust because feedback helps control and improve the system.
A community is rebuilding after a natural disaster. Name TWO technology careers that would help and explain how.
Engineer (designs structures), construction worker (builds safely), city planner (plans layout), etc.
Why is problem-solving more important than memorization in most technology careers?
Because workers must adapt to new problems and design solutions, not just recall facts.
Explain why the Engineering Design Process must be continuous instead of stopping after the first solution works.
Feedback, testing, and new problems require ongoing revisions and improvements.
A toy uses gears to spin wheels while a lever lifts an arm. Identify TWO motion types and where each occurs.
Rotary motion (gears/wheels) and lever motion (arm pivoting).
A system produces output, but the output is poor quality. Which part of the system should be examined first and why?
The process, because it changes the input into the output.
A wind-up toy works without electricity. Explain why it is still considered technology.
Because technology is human innovation used to solve problems, not just electronics.
A toy arm uses a pivot point, moves back and forth, and lifts objects. Identify the simple machine, motion type, and system component involved.
Lever; oscillating or lever motion; process.
