Type: Lesson/Unit Plan

Overview:

Students will look at photographs and read information on blue crabs to understand the changes that a blue crab goes through during molting, and why it is important for scientists to understand these changes.

Content Standard(s):
Science
SC2015 (2015)
Grade: 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.


NAEP Framework
NAEP Statement::
L4.4: When the environment changes, some plants and animals survive and reproduce; others die or move to new locations.


Unpacked Content
Scientific And Engineering Practices:
Engage in Argument from Evidence
Crosscutting Concepts: Systems and System Models; Structure and Function
Disciplinary Core Idea: From Molecules to Organisms: Structures and Processes
Evidence Of Student Attainment:
Students:
  • Argue from evidence to support that the internal and external structures of plants function to support survival, growth, behavior, and reproduction.
  • Argue from evidence to support that the internal and external structures of animals function to support survival, growth, behavior, and reproduction.
Teacher Vocabulary:
  • argue
  • articulate
  • evidence
  • internal
  • external
  • structure
  • survival
  • function
  • behavior
  • 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.
