DRILL

• What is technology?
• What is an artifact?
• A. The application of knowledge, tools, and
  skills to solve problems and extend human
  capabilities.
• B. Human innovation in action that involves the
  generation of knowledge and processes to develop
  systems that solve problems and extend human
  capabilities.
• Something created by humans usually for a
  practical purpose an object remaining from a
  particular period.

UNIT 3 Engineering Design

• Engineering, the systematic application of
  mathematical, scientific, and technical
  principles, produces tangible end products that
  meet our needs and desires.

BIG IDEA
What is a systematic application of something?
an organized or established procedure a set
of steps

LESSONS
4
The Core Technologies

• PURPOSE OF LESSON

• To familiarize students with the core
  technologies (engineering resources) the
  building blocks of the designed world by having
  students identify and describe the core
  technologies as they are applied in the designed
  world.

5
The Core Technologies
Write these down What is a function? The
action for which a thing exists What is an
application? A use to which something is put
6
The Core Technologies
What is technology? The application of
knowledge, tools, and skills to solve problems
and extend human capabilities. What is a
technology system? A Technology System is a
group of subsystems working together to solve
problems and extend human capabilities.
7
What is it made of?
A technology system is a group of resources
(subsystems) working together to solve problems
and extend human capabilities.

• Core Technologies are the subsystems
• Mechanical
• Structural
• Electrical
• Electronic
• Thermal
• Fluid
• Optical
• Bio-Tech
• Material

8
The Core Technologies

• There are several engineering resources (core
  technologies) that are the building blocks of
  all technology systems.
• We could store the core technologies on shelves
• We can go to those shelves and use technologies
  according to our needs in problem solving.

• Your final product will look like
• Steps
• Draw LIGHT construction lines using the
  dimensions to the right.
• Offset lines 3/16
• Vertical lines left
• Horizontal lines down
• Darken the shelves with HEAVY object lines
• Draw LIGHT guidelines
• 3/8 for title
• 5/16 for shelves

10

• Identify the problem that the technology system
  solves.
• Analyze the technology system
• What is its function and/or application?
• List the resources (core technologies) you
  recognize in the technology system.
