2. Scientists
Investigate our
natural world
Technologists
Apply science and
math to designs
Mathematicians
Use numbers and symbols
to solve problems
Engineers
Create our
designed world
STEM
Working together
to solve problems
based on societal
needs and wants

3. Science vs. Technology
•Scientists investigate our natural world
•Engineers help create the human-
designed world
•Technology (or technologies) denotes the
products and processes created by an
engineer and often used by a scientist
(the “stuff” or “things” we use)

4. How are each of them needed to
Create a Product?
Example ScienceTechnologyEngineering Math

your idea with
the resources
you have
Size and
shape
Dimensions

5. How are each of them needed to
Create a Product?
Example ScienceTechnologyEngineering Math
PencilDiscovery of
graphite and
the fact that
rubber
(an eraser)
will remove
graphite
Creating a
writing device
that doesn’t
use ink
Designing a
device with a
graphite insert,
an exterior
holder, and an
attached eraser
What is the
optimal
length,
diameter,
or shape for
the device?

6. Science…Math…
•Knowledge of science and math is
necessary for the creation of new
technologies
•People working in multiple career areas
helped put the cereal you may have eaten
this morning
•Think about the tables and or chairs you
may have used so far today.

7. Scientists…Engineers…
•Information from a scientist helped the
farmer to plant, grow, and harvest the
grains (corn, oats, wheat, rice, and barley)
•The responsibility of an engineer includes
designing the equipment used to harvest
the grain and designing the factory where
the grain was processed into what you eat
today

8. Engineers…Technologists…
•An engineering technologist built the
factory, built the tools and equipment
necessary for converting the grains into
cereal
•Engineering technologists were part of a
team that built the farm equipment (that
an engineer designed)

9. Mathematicians…
•All along the way, mathematicians were
needed to solve problems…like how big the
factory should be or how much cereal
should go in one box
•Have you ever noticed that most cereal
boxes are the same width, but they vary in
height and/or thickness? Why do
you think these particular dimensions are
chosen?

10. What is Engineering?
CONCEPTS
•Science is the study of the natural world,
while technology is the study of how
humans develop new products to meet
needs and wants.
•Teams of people can accomplish more
than one individual working alone.

11. Introduction to Engineering

technologies

12. What is Engineering?

environmental consequences

13. What is Engineering?
CONCEPTS
•Engineers, designers, and engineering
technologists are needed in high demand

used by a technological system

16. What is Engineering?
Key Terms
•Engineering
Using technological and scientific
knowledge to solve practical problems

The study of workplace equipment design
or how to arrange and design devices,
machines, or workspace so that people and
things interact safely and most efficiently

17. What is Engineering?
Key Terms
•Industrial
Anything relating to (or resulting from) industry,
manufacturing, production, etc.
•Invention
A new product, system, or process that has
never existed before, created by study and
experimentation
•Innovation
An improvement of an existing technological
product, system, or method of doing
something

18. What is Engineering?
Key Terms
•Manufacturing
The process of making a raw material into
a finished product; especially in large
quantities
•Math
The science of patterns and order and the
study of measurement, properties, and the
relationships of quantities using numbers
and symbols

19. What is Engineering?
Key Terms
•Nanotechnology
The science and technology of building
devices, such as electronic circuits, from
single atoms and molecules
•Process
Human activities used to create, invent,
design, transform, produce, control,
maintain, and use products or systems; a
sequence of actions that combines
resources to produce an output

20. What is Engineering?
Key Terms
•Science
The study of our natural world through
observation, identification, description,
experimental investigation, and theoretical
explanations
•System
A group of interacting, interrelated, or
interdependent elements/parts that function
together as a whole to accomplish a goal

21. What is Engineering?
Key Terms
•Technology
The way people use resources to meet
their wants and needs; the devices humans use
