Designed World
•
Consists of all the modifications that humans
have made to the natural world to satisfy their
own needs and wants.
7 Categories of the Designed World
•
Medical technology
•
Agricultural/biotechnology
•
Information and communication technology
•
Transportation
•
Energy and power
•
Manufacturing
•
Construction
Class Discussion: Impact of I&I
•
Briefly discuss with your table partner the
impact of the technology that you researched.
Review of Systems
•
Group of interrelated components designed
collectively to achieve a goal.
•
Consists of an input, process, output and at
times feedback.
Example: Electrical System at House
•
Input – electricity
•
Process-electricity converted to light in the
filament
•
Output-light
•
Feedback – no light? Bulb burned out.
Systems work together to make
technology work.
•
Common systems are:
•
Mechanical
•
Fluid
•
Electrical
•
Thermal
•
Chemical
Types of Systems
•
Open-loop: has no feedback and requires
human intervention
Ex. Home stereo system
•
Closed-loop: uses feedback
•
Ex. Electrical timer
Basic Technological Resources
•
Tools and machines
•
Materials
•
Information
•
Energy
•
Capital
•
Time
•
People
Criteria and Constraints
•
Requirements placed on systems and
products.
Ex. American Electrical Systems – wired to use
consumer products that operate on 110-120
volts.
Optimization
•
Making a product, process or system as
functional as possible.
•
Ex. House wiring circuit – should consist of an
“optimal” number of outlets.
Processes
•
Systematic sequence of actions used to
combine resources to produce an output.
Ex. Designing – applying creative skills in the
development of an invention or innovation.
Other processes: maintenance, management
and assessment.
Troubleshooting
•
Used when a system fails in order to find the
source of the problem and fix it.
Controls
•
The mechanisms or activities that use
information to cause a system to change.
•
Ex. Light switch
Components of Transportation
Systems
1.
Structural
2.
Propulsion
3.
Suspension
4.
Guidance
5.
Control
6.
Support
Independent Assignment
•
Research and explain the systems and
subsystems found in transportation vehicles.
Each person at your table will report on one of
the following:
1. Car
2. Train
3. Airplane
4. Motorcycle
Explore the core concepts of technology, the relationship among technologies, and their connection to other fields of study. Delve into the impact of various technologies like medical, agricultural, and information technology. Understand the designed world created by human modifications to meet needs and wants, and discover the categories such as medical technology, transportation, and energy. Engage in discussions about the impact of technology and review of systems designed to achieve goals using input, process, output, and feedback. Learn about different types of systems and basic technological resources.
