PLTW ENGINEERING ESSENTIALS EXAM
REVIEW QUESTIONS AND CORRECT
ANSWERS
◉ patent.
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.
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.
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.
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.
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).
Answer: The sideways and downward movement of the edge of a
plate of the Earth's crust into the mantle beneath another plate.
◉ simulate.
Answer: To reproduce the conditions of (a situation, etc). To use a
model to imitate certain conditions for purposes of study or training.
◉ Computational Thinking.
Answer: Habits that help people solve problems with computers.
Computational thinking habits encourage a person who is facing a
problem to ask how computers could help them be more creative, to
communicate, collaborate, use data or the internet, or use
crowdsourcing or simulation, to solve a problem.
