SC15.4.9

Examine evidence to support an argument that the internal and external structures of plants (e.g., thorns, leaves, stems, roots, colored petals, xylem, phloem) and animals (e.g., heart, stomach, lung, brain, skin) function to support survival, growth, behavior, and reproduction.

Knowledge

Students know:
  • Internal and External structures serve specific functions within plants and animals.
  • The functions of internal and external structures can support survival, growth, behavior and/or reproduction in plants and animals.
  • Different structures work together as part of a system to support survival, growth, behavior, and/or reproduction.

Skills

Students are able to:
  • Articulate an explanation from evidence explaining how the internal and external structures of plants and animals function to support survival, growth, behavior, and reproduction.
  • Determine the strengths and weaknesses of the evidence collected, including whether or not it supports a claim about the role of internal and external structures of plants and animals in supporting survival, growth, behavior, and/or reproduction.
  • Use reasoning to connect the relevant and appropriate evidence to support an argument about the function of the internal and external structures of plants and animals.

Understanding

Students understand that:
  • Plants and animals have both internal and external structures that serve various functions in growth, survival, behavior, and reproduction.
