Engineering Design Process
100

the application of science and mathematics to solve real-life problems

engineering

100

a solid substance that has a conductivity between that of an insulator and that of most metals

semi conductor

100

information, material, or energy resulting from a system or process

output

100

the specific requirements and standards a design should meet

criteria

100

First step is:

Ask questions and define problems.
200

the design and production of materials, structures, and systems that are modeled on biological entities and processes.

biomimicry

200

Four needs that society has for technology:

food, shelter, clothing, safety

200

a limit that defines the edges of a system and the divisions within a system

boundary

200

limitations that define the boundaries of a design process

constraints

200

2nd step: 

Develop and use models
300

the application of science for practical purposes; the use of tools, machines, materials, and processes to meet human needs

technology

300

a set of interacting parts that work together; sometimes considered distinct from their surroundings only for the purpose of study

system

300

 proposed explanation made on the basis of limited evidence as a starting point for further investigation.

hypothesis

300

the act of giving up one design advantage in order to keep another. 

tradeoff

300

3rd step: 

Plan and carry out investigations
400

a fact or situation that is observed to exist or happen 

phenomena

400

the parts of a system that interact and carry out a process or processes

component

400

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

400

4th step: 

Analyze and evaluate data.
500

the amount of space that a substance or object occupies



volume

500

information, material, or energy added to a system or process

input

500

the point at which the deformation changes from elastic to plastic

yield point

500

The 5th, 6th, and 7th steps:

5th. Construct explanations and design solutions

6th. Engage in argument from evidence

7th. Communicate information
