Massachusetts Curriculum Frameworks for Technology/Engineering:

MS-ETS1-1.

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.*

MS-ETS1-5(MA).

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.]

MS-ETS1-6(MA).

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.]


MS-ETS2-1(MA).

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

MS-ETS2-2(MA).

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.]

MS-ETS2-3(MA).

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.]

MS-ETS1-2.

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.*

MS-ETS1-4.

Generate and analyze data from iterative testing and modification of a proposed object, tool, or process to optimize the object, tool, or process for its intended purpose.*

MS-ETS1-7(MA).

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

MS-ETS3-4(MA).

Show how the components of a structural system work together to serve a structural function or maintain and environment for a particular human use. Provide examples of physical structures and relate their design to their intended use. [Clarification Statement: Examples of uses include carrying loads and forces across a span (such as a bridge), providing livable space (such as a house or office building), or providing specific environmental conditions (such as a greenhouse or cold storage). Examples of components of a structural system could include foundation, decking, wall, roofing, inputs (such as heat or AC), and feedback mechanisms.]

MA-ETS3-5(MA).

Use the concept of systems engineering to: a. analyze how components of a transportation, structural or communication system work together or affect each other, and b. model the inputs, processes, outputs, and feedback of a technological system.
