Lesson 1
the application of science and mathematics to solve real-life problems
engineering
a solid substance that has a conductivity between that of an insulator and that of most metals
semi conductor
information, material, or energy resulting from a system or process
output
the specific requirements and standards a design should meet
criteria
First step is:
the design and production of materials, structures, and systems that are modeled on biological entities and processes.
biomimicry
Four needs that society has for technology:
food, shelter, clothing, safety
a limit that defines the edges of a system and the divisions within a system
boundary
limitations that define the boundaries of a design process
constraints
2nd step:
the application of science for practical purposes; the use of tools, machines, materials, and processes to meet human needs
technology
a set of interacting parts that work together; sometimes considered distinct from their surroundings only for the purpose of study
system
proposed explanation made on the basis of limited evidence as a starting point for further investigation.
hypothesis
the act of giving up one design advantage in order to keep another.
tradeoff
3rd step:
a fact or situation that is observed to exist or happen
phenomena
the parts of a system that interact and carry out a process or processes
component
a type of design testing that is repeated many times as part of the engineering design process; the results of each repetition are used to modify the next version of the product or tool
iterative testing
4th step:
the amount of space that a substance or object occupies
volume
information, material, or energy added to a system or process
input
the point at which the deformation changes from elastic to plastic
yield point
The 5th, 6th, and 7th steps:
5th. Construct explanations and design solutions
6th. Engage in argument from evidence
7th. Communicate information
