concensus - general agreement Design Process - A systematic problem-solving strategy, with criteria and constraints, used to develop many possible solutions to solve a problem or satisfy human needs and wants and to winnow (narrow) down the possible solutions to one final choice. optimize - make the best or most effective use of (a situation, opportunity, or resource). graphic organizer - A visual display that demonstrates relationships between facts, concepts, or ideas. A graphic organizer guides the learner's thinking as they fill in and build upon a visual map or diagram Engineering Mindset - A way of thinking that affects how someone interacts with a challenge, comes up with a solution to a problem, and innovates on current technologies or systems. Misconception - A view or opinion that is incorrect because it is based on faulty thinking or understanding. collaboration - Collaboration is the action of two or more people working together through idea sharing to accomplish a common goal. Systems Thinking - Understanding a system by examining the connections between the parts that compose the entirety of the system. system - A group of interacting, interrelated, or interdependent elements or parts that function together as a whole to accomplish a goal. Change happens if you add or remove a part. patent - A government authority or license conferring a right or title for a set period, especially the sole right to exclude others from making, using, or selling an invention.Model - An accurate representation of an object or phenomenon. Models can be visual, physical, mathematical, or computational, and are often used in the development of scientific theories or the engineering of artifacts. conceptual model - A visual representation of an idea. A conceptual model can be a sketch, concept map, schematic, flow chart, or any other visual representation. graphical model - A pictorial representation (such as a picture, map, or technical drawing) used to convey detailed information. In engineering, graphical models are created using standards of engineering graphics to document a design and are often referred to as technical drawings. spatial - Relating to, occupying, or having the character of space. Spatial describes how objects fit together in space or down here on Earth. Subduction(zone) - The sideways and downward movement of the edge of a plate of the Earth's crust into the mantle beneath another plate. simulate - To reproduce the conditions of (a situation, etc). To use a model to imitate certain conditions for purposes of study or training. Computational Thinking - Habits that help people solve problems with computers. Computational thinking habits encourage a person who is facing a problem to ask how computers could help them be more creative, to communicate, collaborate, use data or the internet, or use crowdsourcing or simulation, to solve a problem. data validation - A feature in Excel used to control what a user can enter into a cell. conditional formatting - A feature in Excel that allows the user to automatically apply formatting to one or more cells based on the cell value. algorithmic thinking - Creating a sequence of steps to solve a problem or accomplish a -offs - An exchange of one thing in return for another: especially relinquishment of one benefit or advantage for another regarded as more desirable. ethical issue - A problem or situation that requires a person or organization to choose between alternatives that must be evaluated as right (ethical) or wrong (unethical). ethical dilemma - A situation in which there is a choice to be made between two (or more) options, neither of which resolves the situation in an ethically acceptable fashion. patents - A government authority or license conferring a right or title for a set period, especially the sole right to exclude others from making, using, or selling an invention. sustainable - A method of harvesting or using a resource so that the resource is not depleted or permanently damaged and will still be available for future generations. constructive criticism - The process of offering valid and well-reasoned opinions about the work of others, usually involving both positive and negative comments, in a friendly manner rather than an oppositional one. problem statement - A clear and concise identification and description of the design problem or opportunity. variable - A factor in an experiment that changes and may impact the experimental outcome. testable hypothesis - A proposed explanation that can be affirmed or disproved based on scientific testing using the experimental design process. independent variable - A variable that represents a quantity that is being manipulated in an experiment. The letter x is often the variable used to represent the independent variable in an dent variable - A variable that represents a quantity whose value depends on how the independent variable is manipulated. The letter y is often the variable used to represent the dependent variable in an equation. experimental controls - Controls used as the standards for comparison and providing baseline data. All experimental data is compared to the control data in order to determine if the independent variable has an effect. positive control - Part of a well-designed experiment that shows scientists what a positive result will look like. negative control - A component of an experiment demonstrating what a negative result looks like. Used as a comparison against positive results. qualitative data - Data dealing with descriptors and characteristics, such as color, texture, odor, etc. quantitative data - Data dealing with numbers, such as height, volume, length, time, temperature, etc. composite material - A material made by combining two or more materials, often ones that have very different properties. The materials work together to give the composite unique properties. However, within the composite you can easily tell the different materials apart as they do not dissolve or blend into each other. reliable - Consistently able to perform as expected. durable - Able to maintain structure and function during a life span.
