Clarification Statement - S.P.LS.1.2.CS:
Emphasis should be on the relationships between the physical and living environment. Examples of external parts could include roots, stems, leaves for plants and eyes, ears, mouth, arms, legs for animals.

Science and Engineering Practices - PK2.SEP3.1:
With guidance, plan and conduct an investigation incollaboration with peers.

Disciplinary Core Ideas - S.P.LS.1.2.DCI:
LS1.A: Structure and Function

• All organisms have external parts. Different animals use their body parts in different ways to see, hear, grasp objects, protect themselves, move from place to place, and seek, find, and take in food, water and air. Plants also have different parts (roots, stems, leaves, flowers, fruits) that help them survive and grow.

LS1.D: Information Processing

• Animals have body parts that capture and convey different kinds of information needed for growth and survival. Animals respond to these inputs with behaviors that help them survive. Plants also respond to some external inputs.

Crosscutting Concepts - CC2.2:
Events have causes that generate observable patterns.

Crosscutting Concepts - CC3.1:
Systems in the natural and designed world have parts that work together.

Crosscutting Concepts - CC4.1:
The shape and stability of structures of natural and designed objects are related to their function(s).
