| Term | Definition |
|---|---|
| Technology | The modification of the natural environment in order to satisfy human needs and wants. |
| Technology Literacy | The ability to use, manage, understand, and access technology |
| Materials Technology | The technology of producing, altering, and combining materials. |
| Transportation Technology | The technology of transporting people and goods. |
| Information & Communication Technology | The technology of communicating to people and machines |
| Medical Technology | The technology of caring for the sick and curing disease |
| Agricultural & Bio Technology | The technology of farming and DNA |
| Construction Technology | The technology of building and maintaining structures |
| Energy & Power Technology | The technology of producing and transferring energy into work/power |
| Manufacturing Technology | the technology of producing goods in a factory |
| Science | The knowledge of the natural world (Discovery). Helps us develop technology |
| Invention | A totally new product, produced from ideas and imagination |
| Innovation | An improvement to an invention. You will have more innovations than inventions |
| Positive Outcomes vs. Negative Outcomes | Positive: technology solves problems, Negative: creates new problems |
| Systems Model | A group of units/parts that work together. Consists of input, process, output and sometimes feedback |
| 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 |
| Systems Thinking | Viewing problems as parts of an overall system.What component is causing the problem |
| Controls | Mechanisms or steps that are performed using information about the system that cause the system to change |
| 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 |
| 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 |
| Criteria | The problem you are trying to solve/the goal of your design. Example: Design a bridge |
| Constraint | Limitations to your design. You may have a time limit, money limit or specifications for the appearance. |
| Prototype | A full scale working model of the product. For example the crash car used to test car safety |
| 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 |
| Mechanical Advantage | A force that is increased by the use of a machine. Ex. using a drill to drive a screw |
