  1. 4. Divisor; the number below the line in a fraction.
  2. 5. The act or process of building, erecting, or constructing buildings, roads, or other structures.
  3. 7. System The decimal measuring system based on the meter, liter, and gram as units of length, capacity, and weight or mass.
  4. 9. The number above the line in a fraction showing how many of the parts indicated by the denominator is taken.
  5. 11. The science of patterns and order and the study of measurement, properties, and the relationships of quantities using numbers and symbols.
  6. 12. A tool for systematically ranking alternatives according to a set of criteria.
  7. 13. A limit to the design process. Constraints may be such things as appearance, funding, space, materials, and human capabilities.
  8. 16. A systematic problem-solving strategy, with criteria and constraints, used to develop many possible solutions to a problem or to satisfy human needs and wants and winnow (narrow) down the possible solutions to one final choice.
  9. 18. Desired specifications (elements or features) of a product or system.
  10. 20. The condition or quality of being true, correct, or exact; precision; exactness. The degree of correctness of a quantity or expression.
  11. 22. The way people use resources to meet their wants and needs.
  12. 23. A group of interacting, interrelated, or interdependent elements or parts that function together as a whole to accomplish a goal.
  13. 24. An iterative decision-making process that produces plans by which resources are converted into products or systems that meet human needs and wants or solve problems.

  1. 1. A visual, mathematical, or three-dimensional representation in detail of an object or design, often smaller than the original. A model is often used to test ideas, make changes to a design, and to learn more about what would happen to a similar, real object.
  2. 2. The transmission of information through a common system of symbols, signs, behavior, speech, writing, or signals.
  3. 3. A full-scale working model used to test a design concept by making actual observations and necessary adjustments.
  4. 6. A new product, system, or process that has never existed before, created by study and experimentation.
  5. 8. A method of shared problem solving in which all members of a group spontaneously, and in an unrestrained discussion, generate ideas.
  6. 10. Using technological and scientific knowledge to solve practical problems.
  7. 14. An improvement of an existing technological product, system, or method of doing something.
  8. 15. System also referred to as the English system of measuring. The measuring system based on the foot, second, and pound as units of length, time, weight, or mass
  9. 16. 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.
  10. 17. The study of our natural world through observation, identification, description, experimental investigation, and theoretical explanations.
  11. 19. A human-made object.
  12. 21. A person who is trained in and uses technological and scientific knowledge to solve practical problems.
