PLTW EES Unit 1 Vocabulary

Match the following

• 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

• General agreement.

• innovative

• 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.

• consensus

• 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.

• design process

• Improving an existing technological product, system, or method of doing something. 

Match the following

• sustainable

• A view or opinion that is incorrect because it is based on faulty thinking or understanding.

• vaccine

• 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.

• misconception

• Collaboration is the action of two or more people working together through idea sharing to accomplish a common goal.

• ethical dilemma

• A substance used to stimulate the production of antibodies and provide immunity against one or several diseases.

• collaboration

• 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.     

Match the following

• systems model

• 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

• Understanding a system by examining the connections between the parts that compose the entirety of the system.

• system

• 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.

• systems thinking

• An abstract representation of a system that identifies interacting elements and components of the system and the relationships among those components and elements.

Match the following

• graphical model

• The sideways and downward movement of the edge of a plate of the Earth's crust into the mantle beneath another plate.  

• subduction

• Relating to, occupying, or having the character of space. Spatial describes how objects fit together in space or down here on Earth.

• spatial

•  A visual representation of an idea. A conceptual model can be a sketch, concept map, schematic, flow chart, or any other visual representation.   

• conceptual 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.

Match the following

• logistics

• The detailed coordination of a complex operation involving many people, facilities, or supplies.

• optimization

• Creating a sequence of steps to solve a problem or accomplish a task.

• algorithmic thinking

• Making the best or most effective use of resources to get the best possible solution.

• 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.

Match the following

• constructive criticism

• 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.     

• 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).

• problem statement

• 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.

• sustainable

• A clear and concise identification and description of the design problem or opportunity.

• ethical dilemma

• 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.

Match the following

• independent variable

• 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.  

• dependent 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 equation.

• experimental controls

• A factor in an experiment that changes and may impact the experimental outcome.

• 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.

• testable hypothesis

• A proposed explanation that can be affirmed or disproved based on scientific testing using the experimental design process.

Match the following

• experimental controls

• Data dealing with descriptors and characteristics, such as color, texture, odor, etc.

• quantitative data

• 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.  

• qualitative data

• Data dealing with numbers, such as height, volume, length, time, temperature, etc.

Match the following

• reliable

• Consistently able to perform as expected.

• composite material

• Percentage of an object that is solid material inside.

• infill density

• Able to maintain structure and function during a life span.

• validate

• 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.

• durable

• To check or prove the accuracy of (something).

Match the following

• stakeholder

• A written plan that identifies a problem to be solved, its criteria, and its constraints. The design brief is used to encourage thinking of all aspects of a problem before attempting a solution.

• measurable

• An individual, group, or organization who may affect, be affected by, or perceive itself to be affected by a decision, activity, or outcome of a project.

• design brief

• Design criteria that provides a precise indicator of a quantifiable characteristic so that a design can be compared to the criteria and deemed acceptable or unacceptable.
