"PLTW Engineering Essentials" detailed questions with verified
solutions (A+ Grade 2026\2027)
concensus
- correct answer general agreement
Design Process
- correct answer A systematic problem-solving strategy, with criteria and constraints, used to develop
many possible solutions to solve a problem or satisfy human needs and wants and to winnow (narrow)
down the possible solutions to one final choice.
optimize
- correct answer make the best or most effective use of (a situation, opportunity, or resource).
graphic organizer
- correct answer A visual display that demonstrates relationships between facts, concepts, or ideas. A
graphic organizer guides the learner's thinking as they fill in and build upon a visual map or diagram
Engineering Mindset
- correct answer A way of thinking that affects how someone interacts with a challenge, comes up with
a solution to a problem, and innovates on current technologies or systems.
Misconception
- correct answer A view or opinion that is incorrect because it is based on faulty thinking or
understanding.
collaboration
- correct answer Collaboration is the action of two or more people working together through idea
sharing to accomplish a common goal.
Systems Thinking
- correct answer Understanding a system by examining the connections between the parts that
compose the entirety of the system.
, system
- correct answer A group of interacting, interrelated, or interdependent elements or parts that function
together as a whole to accomplish a goal. Change happens if you add or remove a part.
patent
- correct answer A government authority or license conferring a right or title for a set period, especially
the sole right to exclude others from making, using, or selling an invention.
Model
- correct answer An accurate representation of an object or phenomenon. Models can be visual,
physical, mathematical, or computational, and are often used in the development of scientific theories
or the engineering of artifacts.
conceptual model
- correct answer A visual representation of an idea. A conceptual model can be a sketch, concept map,
schematic, flow chart, or any other visual representation.
graphical model
- correct answer A pictorial representation (such as a picture, map, or technical drawing) used to convey
detailed information. In engineering, graphical models are created using standards of engineering
graphics to document a design and are often referred to as technical drawings.
spatial
- correct answer Relating to, occupying, or having the character of space. Spatial describes how objects
fit together in space or down here on Earth.
Subduction(zone)
- correct answer The sideways and downward movement of the edge of a plate of the Earth's crust into
the mantle beneath another plate.
simulate
- correct answer To reproduce the conditions of (a situation, etc). To use a model to imitate certain
conditions for purposes of study or training.
