Strand III
Use Scientific Knowledge from the Life Sciences in Real-World Contexts

 

Science/Strand III
Content Standard 2
All students will use classification systems to describe groups of living things; compare and contrast differences in the life cycles of living things; investigate and explain how living things obtain and use energy; and analyze how parts of living things are adapted to carry out specific functions. (Organization of Living Things)

Science/Strand III/Content Standard 2/Elementary
Benchmark 1
Explain characteristics and functions of observable body parts in a variety of animals.

Benchmark Clarification

Animals can be sorted by their observable body parts. Students will categorize an animal according to its characteristics and how the characteristics work.

Examples:

  • Insulation: fur, feathers, blubber
  • Support: exoskeleton (outer), endoskeleton (inner)
  • Food-Getting: claws, beaks, teeth
  • Protection: quills, horns, claws, eyes
  • Movement: legs, wings, fins, webbed feet

Students will:

  • Categorize an animal according to its characteristics and how those characteristics work
  • Categorize vertebrates — animals with a backbone
  • Categorize invertebrates — animals without a backbone

Instructional Example
Benchmark Question: What are the functions of observable body parts of animals?
Focus Question: It’s a part; what’s its function?

Students will select a familiar animal to analyze. All observable body parts of the chosen animal will be listed. Then students will work to put each of the body parts into at least one of the function categories listed in the Benchmark Clarification Section.

Constructing: (SCI.I.1.E.1), (SCI.I.1.E.2), (SCI.I.1.E.5), (SCI.II.1.E.3), (SCI.II.1.E.4).

 

Science/Strand III/Content Standard 2/Elementary/Benchmark 1
Assessment Example
Each student will invent an animal that shows an observable body part for each of the following functions: insulation, support, movement, foodgetting, and protection. Each student must present his or her design in one of the following forms: storybook, flipbook, multi-media presentation, 3D model, or drama.

This presentation must also include a written explanation of the body’s observable characteristics and the function that each fulfills. Written presentations may be in one of the following forms: story, poem, song, or report.

(Give students rubric before activity.)
