What This Standard Means
What Students Need to Do
- Students identify body parts and actions animals use to get food, water, and oxygen. They record observations and compare how two animals meet the same need differently.
What Mastery Looks Like
- A student can name a relevant structure or behavior and explain its job using evidence. The student can organize observations in a table and state a clear similarity or difference.
Common Misconceptions
- Students may confuse a body structure, such as a beak, with a behavior, such as pecking. They may think all animals drink water or breathe air in the same way.
How to Assess It
- Show pictures of a duck and a fish. Ask students to name one structure or behavior each uses to get food, water, or oxygen, then compare them.

Ways to Teach It
Use spoons, tweezers, and clothespins as beaks to collect different foods, then record which tool works best for each food.
Show a hummingbird and frog, then ask students to write how each animal's body and actions help it get food.
Play a card match game pairing animals with structures, behaviors, and needs, such as a fish, gills, swimming, and oxygen.
Observe birds at a feeder or watch a short feeder video, then record how beaks and movements help different birds eat.
