Additional Info


Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution. Include potential impacts on people and the natural environment that may limit possible solutions.*


Create visual representations of solutions to a design problem. Accurately interpret and apply scale and proportion to visual representations.* [Clarification Statement: Examples of visual representations can include sketches, scaled drawings, and orthographic projections. Examples of scale can include ’’ = 1’0’’, 1 cm = 1 m.]


Communicate a design solution to an intended user, including design features and limitations of the solution. [Clarification Statement: Examples of intended users can include students, parents, teachers, manufacturing personnel, engineers, and customers.]


Analyze and compare properties of metals, plastics, wood and ceramics, including stiffness, strength, ductility, hardness, thermal conductivity, electrical conductivity, and melting point.


Given a design task, select appropriate materials based on specific properties needed in the construction of a solution. [Clarification Statement: Examples of materials can include metals, plastics, wood, and ceramics.]


Choose and safely use appropriate measuring tools, hand tools, fasteners and common power tools used to construct a prototype.* [Clarification Statement: Examples of measuring tools include a tape measure, a meter stick, and a ruler. Examples of hand tools include a hammer, a screwdriver, a wrench and pliers. Examples of fasteners include nails, screws, nuts and bolts, staples, glue, and tape. Examples of common power tools include jig saw, drill, and sander.]


Evaluate competing solutions to a given design problem using a systematic process to determine how well each meets the criteria and constraints of the problem. Use a model of each solution to evaluate how variations in one or more design features, including size, shape, weight, or cost, may affect the function or effectiveness of the solution.*


Construct a prototype of a solution to a given design problem.*
