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. |
