  • Use appropriate tools and techniques to gather, analyze, and interpret data.
  • Given evidence, develop descriptions, explanations, predictions, and models.
  • Show the relationship between evidence and explanations.
  • Recognize and analyze alternative explanations and predictions.
  • Communicate scientific procedures and explanations.
  • Use mathematics in scientific inquiry.

8.4.4 By the end of eighth grade, students will develop an understanding of populations and ecosystems.
Example Indicators:

  • Investigate and describe that a population consists of all individuals of a species at a given place and time.
  • Investigate and analyze the living and nonliving factors that determine the number of organisms an ecosystem can support.
  • Describe an organism by the function it serves in an ecosystem (e.g., producer, consumer, and decomposer).
