QuestionAnswer
Technology : Modifying the natural environment to satisfy human needs and wants.
criteria A goal or problem that you are solving. Your solution must solve this problem. S
constriant : A goal or problem that you are solving. Your solution must solve this problem
system A group of units or parts that work together.
subsystem Unique, independent systems necessary for the overall structure or system to function.
open-loop system : A system in which there is no feedback. (Input>Process>Output)
closed-loop system : A system in which there is feedback. (Input>Process>Output>Feedback)
input Anything put in to a system. Can be capital ($), raw materials, people (labor), fuel, etc.
PROCESS : The process of changing/using the inputs. Ex. The burning of the fuel to produce power/work in an engine.
Stem intergration The combination of Science, Technology, Engineering, and Mathematics in Technology, Engineering, and Design.
science knowledege for tech Using scientific theory/discoveries to advance technology. Constraint: A limitation to your design. It could be money, size, color, etc. Social Studies for Tech: Examining
language arts for tech Using speaking and writing skills for technology. For example, writing a technical report about a design.
mathematics for tech Using mathematics for the design of inventions/technology. For example, using geometry to design a structure.
tech effects enviroment Technology can have harmful effects on the environment, such as pollution. Air pollution laws would be an example of this relationship.
upcycling The process of using unwanted materials to create a new product of better quality.
recycling The process of using discarded material as a resource for new things.
transporation tech Technology that makes it easier to transport people or goods
output The results of the system. Can be power, movement, a product, etc
feedback The results of the system. Can be power, movement, a product, etc
positive impacts When a technology solves problems and makes life easier for humans
negative impacts When a technology creates problems and has consequences for humans.
maintenance Checking components of a system before they breakdown.
newton 1 law Force = mass x acceleration. The greater the mass, the more force that is needed to move it
newtons 2 law For every action, there is an equal and opposite reaction
newton 3 laws Unlimited (wind, solar), Non-Renewable (will run out, like oil), Renewable (will replenish with time, like bio fuels).
types of energy : Suspension, Propulsion, Structure, and Support (support provides maintenance).
sub-systems for transportation tech : Technology that makes it easier to construct structures like buildings and bridges.
construction tech Technology that makes it easier to encode, transmit, and decode messages
communication tech Technology that makes it easier to diagnose and cure diseases.
medical tech Technology that makes the manufacture of goods in a factory easier.
manufaucturing tech Technology that makes it easier to grow crops and feed the populous.
agricultural revolution Agriculture changed the humans lived because they stopped being hunters and gatherers and started living in cities.
hydroponics The use of biotechnology research produced hydroponics. Hydroponics makes it possible to grow food without the use of soil.
