His cartoons combined simple machines and common household items to create complex, wacky and diabolically logical machines that accomplished mundane and trivial tasks. (Show students a few Rube Goldberg cartoons that feature his crazy inventions.) For 55 years, Rube Goldberg's award winning cartoons satirized machines and gadgets that he saw as excessive. Student Activity Worksheet (pdf) Visit [ to print or download.Ī familiarity with the six types of simple machines: inclined plane, wedge, screw, lever, wheel and axle, and pulley.Ībility to safely use tools, such as screwdrivers, saws, drills and hammers. Identify the five elements of a universal systems model: goal, inputs, processes, outputs, and feedback. Identify appropriate materials, tools, and machines needed to construct a prototype of a given engineering design.Įxplain how such design features as size, shape, weight, function, and cost limitations would affect the construction of a given prototype. Identify and explain the safe and proper use of measuring tools, hand tools, and machines (e.g., band saw, drill press, sander, hammer, screwdriver, pliers, tape measure, screws, nails, and other mechanical fasteners) needed to construct a prototype of an engineering design.ĭemonstrate methods of representing solutions to a design problem, e.g., sketches, orthographic projections, multiview drawings.ĭescribe and explain the purpose of a given prototype. Identify and explain appropriate measuring tools, hand tools, and power tools used to hold, lift, carry, fasten, and separate, and explain their safe and proper use. Make two-dimensional and three-dimensional representations of the designed solution.ĭifferentiate between inputs, processes, outputs, and feedback in technological systems.ĭevelop innovative products and systems that solve problems and extend capabilities based on individual or collective needs and wants.Ĭreate solutions to problems by identifying and applying human factors in design.Īnalyze how an invention or innovation was influenced by its historical context. Specify criteria and constraints for the design. International Technology and Engineering Educators Association - Technologyīrainstorming is a group problem-solving design process in which each person in the group presents his or her ideas in an open forum. Specification of constraints includes consideration of scientific principles and other relevant knowledge that is likely to limit possible solutions.Īll human activity draws on natural resources and has both short and long-term consequences, positive as well as negative, for the health of people and the natural environment.Īlignment agreement: Thanks for your feedback! The uses of technologies and any limitations on their use are driven by individual or societal needs, desires, and values by the findings of scientific research and by differences in such factors as climate, natural resources, and economic conditions. The more precisely a design task's criteria and constraints can be defined, the more likely it is that the designed solution will be successful. This activity focuses on the following Three Dimensional Learning aspects of NGSS:ĭefine a design problem that can be solved through the development of an object, tool, process or system and includes multiple criteria and constraints, including scientific knowledge that may limit possible solutions.Īlignment agreement: Thanks for your feedback!
