• Life Science
  • Structure and function in living systems
    • All organisms are composed of cells--the fundamental unit of life (5-8)
  • Diversity and adaptations of organisms
    • Millions of species of animals, plants, and microorganisms are alive today. (5-8)
    • Although different species might look dissimilar, the unity among organisms becomes apparent from an analysis of internal structures, the similarity of their chemical processes, and the evidence of common ancestry. (5-8)
    • Species acquire many of their unique characteristics through biological adaptation, which involves the selection of naturally occurring variations in populations. (5-8)

• Science as Inquiry
  • Abilities necessary to do scientific inquiry
    • Ask a question about objects, organisms, and events in the environment. (K-4)
    • Use appropriate tools and techniques to gather, analyze, and interpret data.
  • Understandings about scientific inquiry
    • Types of investigations include describing objects, events, and organisms; classifying them; and doing a fair test (experimenting).
    • Scientists develop explanations using observations (evidence) and what they already know about the world (scientific knowledge). Good explanations are based on evidence from investigations. (K-4)
