Use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem.

Performance Expectation

Grade: 
High School (9-12)
Develop a model to illustrate the role of photosynthesis and cellular respiration in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere.

Performance Expectation

Grade: 
High School (9-12)
Evaluate the claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions, but changing conditions may result in a new ecosystem.

Performance Expectation

Grade: 
High School (9-12)
Design, evaluate, and refine a solution for reducing the impacts of human activities on the environment and biodiversity.*

Performance Expectation

Grade: 
High School (9-12)
Evaluate evidence for the role of group behavior on individual and species’ chances to survive and reproduce.

Performance Expectation

Grade: 
High School (9-12)
Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring.

Performance Expectation

Grade: 
High School (9-12)
Make and defend a claim based on evidence that inheritable genetic variations may result from (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors.

Performance Expectation

Grade: 
High School (9-12)
Apply concepts of statistics and probability to explain the variation and distribution of expressed traits in a population.

Performance Expectation

Grade: 
High School (9-12)
Communicate scientific information that common ancestry and biological evolution are supported by multiple lines of empirical evidence.

Performance Expectation

Grade: 
High School (9-12)
Construct an explanation based on evidence that the process of evolution primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the proliferation of those organisms that are better able to survive and reproduce in the environment.
