Evaluate competing design solutions for maintaining biodiversity and ecosystem services.*

Performance Expectation

Grade: 
Middle School (6-8)
Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.

Performance Expectation

Grade: 
Middle School (6-8)
Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.

Performance Expectation

Grade: 
Middle School (6-8)
Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.

Performance Expectation

Grade: 
Middle School (6-8)
