LS1.A: 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.

 

Choose the letter for each body structure that is used for each function that helps the animals survive (Hint: some may use more than one).

Fulfillment of Next Generation Science Standards (NGSS)

Grade 1 - 1-LS1 From Molecules to Organisms: Structures and Processes
Disciplinary Core Ideas

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. (1-LS1-1)

 

Grade 4 - 4-LS1 From Molecules to Organisms: Structures and Processes
Disciplinary Core Ideas

 LS1.A: Structure and Function
• Plants and animals have both internal and external structures that serve various functions in growth, survival, behavior, and reproduction. (4-LS1-1)

Performance Expectations Students who demonstrate understanding can:

4-LS1-1. Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction.  [Clarification Statement: Examples of structures could include thorns, stems, roots, colored petals, heart, stomach, lung, brain, and skin.] [Assessment Boundary: Assessment is limited to macroscopic structures within plant and animal systems.]
