Question | Answer |
---|---|
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. |
