Simple chart helping students categorize animals based on where they live and their physical traits.

Let’s go step by step to fill in the table for each animal. We’ll use what we know about real animals — simple facts that match what you’d learn in school.

---

Bear:
- Lives where? → Land (bears walk on land, even though some swim)
- Type of skin? → Fur (thick fur, not hide like a cow)
- Size? → Bigger than a person (most bears are larger than humans)
- Kind of babies? → Live babies (mammals give birth to live young)

Fish:
- Lives where? → Sea (or water — but since “sea” is an option and fish live in water, we’ll say sea; note: some fish live in freshwater lakes/rivers, but “sea” is acceptable here as general aquatic habitat)
- Type of skin? → Scales (fish have slippery scales)
- Size? → Smaller than a person (most common fish people think of — like goldfish, tuna, salmon — are smaller than a human; yes, some huge fish exist, but generally, we say smaller)
- Kind of babies? → Eggs (most fish lay eggs)

Bird:
- Lives where? → Air (birds fly in air, though they also live on land — but “air” is their main movement space; however, many birds nest on land or trees. Since the options are land/sea/air, and birds spend time in all, but “air” is most distinctive. But wait — actually, birds *live* on land (nesting, eating), but move through air. Let’s check standard answers: usually, birds are said to live on land AND air, but since only one choice allowed, and “air” is unique to them, but technically they rest on land. Hmm. Looking at typical elementary tables: often “land” is used because they build nests on ground/trees. But let’s be accurate: Birds are terrestrial animals that fly. So “land” is safer. However, some might argue “air”. Let me double-check with common curriculum: In many 2nd–4th grade science sheets, birds are listed under “land” because they don’t live in water permanently, and “air” isn’t really a place they “live” — it’s where they travel. Actually, better answer: Land — because they sleep, eat, raise babies on land/trees. Air is how they move.)
Wait — correction: The column says “Lives where?” — meaning habitat. Birds primarily inhabit land environments (forests, fields, cities) and use air to move. They don’t live in air permanently. So “land” is correct.
But let’s see whale — lives in sea. Fish — sea. Cow — land. So bird should be land too? But then why include “air”? Maybe for flying animals. Actually, looking at this table design, “air” is probably meant for birds. Because otherwise, no animal uses “air”. Let’s think: if we put “land” for bird, then “air” is unused. That seems odd. Perhaps the intended answer is “air” for bird — meaning they are aerial creatures. I’ve seen worksheets where birds are listed under “air”. To avoid confusion, let’s go with common educational practice: Bird → Air (as their primary mode of life/movement).

Actually, let’s resolve this properly:

Standard classification in such tables:
- Mammals on land: cow, bear, horse
- Aquatic: fish, whale
- Aerial: bird

So:
→ Bird: Air

Type of skin? → Feathers (not fur, not scales, not hide)
Size? → Smaller than a person (most birds — robin, eagle, pigeon — are smaller than a human; ostrich is bigger, but again, general case)
Kind of babies? → Eggs (all birds lay eggs)

Whale:
- Lives where? → Sea (whales are marine mammals)
- Type of skin? → Smooth skin (no fur, no scales — just smooth blubber-covered skin)
- Size? → Bigger than a person (blue whale is biggest animal ever; even small whales are bigger than humans)
- Kind of babies? → Live babies (whales are mammals — give birth to live young)

Horse:
- Lives where? → Land
- Type of skin? → Hide with short fur (similar to cow — horses have hair/fur over hide)
- Size? → Bigger than a person (adult horses are taller and heavier than humans)
- Kind of babies? → Live babies (mammal)

Now let’s compile:

Final filled table:

| Animal | Lives where? | Type of skin? | Size? | Kind of babies? |
|--------|--------------|---------------------|-------------------|------------------|
| cow | land | hide with short fur | bigger | live babies |
| bear | land | fur | bigger | live babies |
| fish | sea | scales | smaller | eggs |
| bird | air | feathers | smaller | eggs |
| whale | sea | smooth skin | bigger | live babies |
| horse | land | hide with short fur | bigger | live babies |

Note: For “bird”, if your teacher expects “land” instead of “air”, that’s possible — but given the options and typical worksheet design, “air” is likely intended to distinguish flying animals. If unsure, you can ask your teacher — but based on logic and common usage in such charts, “air” fits best for bird.

Also, for “fish”: while some fish are bigger than a person (like whale shark), the general expectation in elementary level is “smaller”. Same for bird — ostrich is big, but we go with typical.

Final Answer:
bear: land, fur, bigger, live babies
fish: sea, scales, smaller, eggs
bird: air, feathers, smaller, eggs
whale: sea, smooth skin, bigger, live babies
horse: land, hide with short fur, bigger, live babies
