[7.ETS.1.2] - Evaluate competing solutions to a given design problem using a decision matrix 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.*
[WCA.6-8.9] -
Draw evidence from informational texts to support analysis, interpretation, reflection, and research. (See grades 6-8 Reading Standard 1 for more on the use of textual evidence.)
[7.RP.A.2.a] -
Decide whether two quantities are in a proportional relationship, e.g., by testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin.
[7.LS.2.5] -
Evaluate competing design solutions for protecting an ecosystem. Discuss benefits and limitations of each design.*
Clarification Statements: Examples of design solutions could include water, land, and species protection and the prevention of soil erosion. Examples of design solution constraints could include scientific, economic, and social considerations.
[7.ETS.1.7] -
Construct a prototype of a solution to a given design problem.*
