Lesson 2
Technology Design and Innovation
Vocabulary
Technology literate, system, models,
modeling, resource, requirement,
trade-off, optimization, process,
control, feedback
Technology Literate
Understand Technology
Identify a technology you understand
Technology is created to meet human needs
If you are technology literate you understand how processes work and
how products work , and understand that the laws of nature limit
what technology can do.
Systems
Key ideas set fields of study apart
• Geometry is different than Algebra
Key ideas for technology involve systems
• Systems are interrelated parts that work together
to produce a desired result.
Example:
• Schools (teachers, students, text books)
Tractor (engine, wheels, and plow)
Describe a system, what are the parts?
Models
• Represent a system, process, product,
structure or environment
• Can be graphic (drawing)
• Physical (scale model) Ex: toy car
• Virtual (computer game)
• Mathematical (graph, chart)
Models etc…
• Represent, analyze, predict, and explain the
performance of a device or system
• Often built before final product is produced
Model of building for architect
Identify a model in the real world
Resources
• Any type of supply, service, or support
Seven types:
1) People
2) Capital (money)
3) Time
4) Information
5) Energy
6) Tools
7) machines
Part 2 of Lesson 2
IF….
If you created a new technology that
used the sun to make and receive texts
what would your resources be for the
project?
Requirements
• Define the performance of a system
– New car design
•
•
•
•
How quickly should it accelerate?
How fuel efficient must it be?
How should information be displayed to the driver?
How much room is required for the driver?
Trade-Offs
• Technologists who develop products often
cannot include everything they want in their
design due to costs of materials
• They have give up one option in order to gain
a more realistic option
– A tire that offers better traction might be better
performing for a car design but the manufacture
has to make a trade-off when choosing the brand,
costs, and warranty option for the tire when
considering the total costs for the customer.
