technology
Term | Definition |
---|---|
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 |
Constraint | A limitation to your design. It could be money, size, color, etc. |
System | A group of units or parts that work together |
Sub-System | 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 Integration | The combination of Science, Technology, Engineering, and Mathematics in Technology, Engineering, and Design |
Science Knowledge for Tech | Using scientific theory/discoveries to advance technology |
Social Studies for Tech | Examining technology’s impact on society |
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 on the Environment | 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 |
Transportation 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 | Information about the system that can be used to alter the system. Can be a gauge or other measurements |
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’s 1st Law | An object remains still or remains in motion unless acted upon by an outside force |
Newton’s 2nd Law | Force = mass x acceleration. The greater the mass, the more force that is needed to move it |
Newton’s 3rd Law | For every action, there is an equal and opposite reaction |
Types of Energy | Unlimited (wind, solar), Non-Renewable (will run out, like oil), Renewable (will replenish with time, like bio fuels) |
Sub-Systems for Transportation Tech | Suspension, Propulsion, Structure, and Support (support provides maintenance) |
Construction Tech | Technology that makes it easier to construct structures like buildings and bridges |
Communication Tech | Technology that makes it easier to encode, transmit, and decode messages |
Medical Tech | Technology that makes it easier to diagnose and cure diseases |
Manufacturing Tech | Technology that makes the manufacture of goods in a factory easier |
Agricultural & Bio Tech | Technology that makes it easier to grow crops and feed the populous |
Energy & Power Tech | Technology that aides us in the production of energy and power in the form of electricity, engines, etc. (Examples: Nuclear Power Plant, Car Engine, etc.) |
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 |
