Grade 3 science worksheet on vertebrate classification, matching animals to their respective classes.

Let's solve the Vertebrate Classification worksheet step by step.

---

🔍 Goal:

Match each animal to its correct class of vertebrates based on characteristics.

We are given 5 classes with defining traits:

1. Birds:
- Feathers, lay eggs, have wings, warm-blooded

2. Mammals:
- Have hair/fur, give live birth (usually), nurse young, warm-blooded

3. Reptiles:
- Dry, scaly skin, lay eggs, cold-blooded

4. Amphibians:
- Moist skin, lay eggs in water, usually live near water, cold-blooded

5. Fish:
- Live in water, have gills, fins, cold-blooded

---

Now let’s examine each animal and match it to the correct class.

---

🐾 Animals on the Left Side:

1. Chimpanzee
- Has fur, gives live birth, nurses young, warm-blooded → Mammal

2. Halling *(likely a typo for "frog")*
- Frog has moist skin, lays eggs in water, lives near water → Amphibian

3. Minnow
- Lives in water, has gills, fins → Fish

4. Hummingbird
- Feathers, wings, lays eggs, warm-blooded → Bird

5. Iguana
- Scaly skin, lays eggs, cold-blooded → Reptile

🐾 Animals on the Right Side:

6. Fire-bellied newt
- Newts are amphibians; live in water/semi-aquatic, moist skin, lay eggs → Amphibian

7. Salmon
- Fish that lives in water, has gills and fins → Fish

8. Vampire bat
- Has fur, gives live birth, nurses young, warm-blooded → Mammal

9. Turtle
- Scaly skin, lays eggs, cold-blooded → Reptile

10. Emperor penguin
- Feathers, lays eggs, wings (flippers), warm-blooded → Bird

✔ Final Matching:

| Animal | Class |
|--------------------|--------------|
| Chimpanzee | Mammals |
| Halling (frog) | Amphibians |
| Minnow | Fish |
| Hummingbird | Birds |
| Iguana | Reptiles |
| Fire-bellied newt | Amphibians |
| Salmon | Fish |
| Vampire bat | Mammals |
| Turtle | Reptiles |
| Emperor penguin | Birds |

📝 Summary:

- Birds: Hummingbird, Emperor penguin
- Mammals: Chimpanzee, Vampire bat
- Reptiles: Iguana, Turtle
- Amphibians: Frog (halling), Fire-bellied newt
- Fish: Minnow, Salmon

✔ Answer Key (for matching):
- Chimpanzee → Mammals
- Halling → Amphibians
- Minnow → Fish
- Hummingbird → Birds
- Iguana → Reptiles
- Fire-bellied newt → Amphibians
- Salmon → Fish
