An interactive science worksheet where students sort animal images into categories like Extinct, Endangered, and Non-Endangered.

Here's the correct classification for each animal image based on current scientific and conservation status (as of 2024):

---

✔ NON-ENDANGERED
*(Species with stable or increasing populations, not currently at risk of extinction)*

- Hyena – Spotted hyenas are listed as “Least Concern” by the IUCN. They have large populations across Africa.
- Cheetah – *Note: While cheetahs are classified as “Vulnerable” by IUCN, they are sometimes grouped under “non-endangered” in simplified educational materials because they are not yet “Endangered.” However, strictly speaking, they are not “non-endangered.” But given the context of this worksheet likely being for younger students, and since there’s no “Vulnerable” column, it may be placed here to contrast with truly endangered species. For accuracy, we’ll place it under ENDANGERED — see note below.*
- Giraffe – The overall giraffe population is listed as “Vulnerable,” but some subspecies are endangered. In simplified contexts, it may be considered non-endangered. However, recent assessments show significant declines, so it’s borderline.

> ⚠️ Important Note: In strict conservation terms, “Non-Endangered” usually means “Least Concern.” Cheetahs and giraffes are NOT Least Concern. But since this worksheet only has 3 columns, and the goal is to sort into broad categories, we will use the most common educational interpretation:

➡️ Revised for Educational Context:

NON-ENDANGERED:
- Hyena (Spotted Hyena – Least Concern)
- *(Cheetah and Giraffe are often mistakenly placed here in school worksheets, but correctly belong in Endangered/Vulnerable)*

---

✔ EXTINCT
*(Species that no longer exist)*

- Tyrannosaurus Rex – A dinosaur that went extinct ~66 million years ago.
- Woolly Mammoth – Went extinct around 4,000 years ago (last population on Wrangel Island).
- Smilodon (Saber-toothed Cat) – Extinct ~10,000 years ago.

---

✔ ENDANGERED
*(Species facing a very high risk of extinction in the wild)*

- Rhinoceros – All rhino species are endangered or critically endangered due to poaching and habitat loss.
- Gorilla – Both Eastern and Western gorillas are classified as “Endangered” or “Critically Endangered.”
- Cheetah – Listed as “Vulnerable” by IUCN, but often included in “Endangered” category in simplified educational materials because their population is declining rapidly (~7,000 left).
- Giraffe – Officially “Vulnerable,” but again, often grouped with endangered in school contexts due to steep population drops (~40% decline in 30 years).

## 📋 Final Correct Sorting (Educational Level):

| NON-ENDANGERED | EXTINCT | ENDANGERED |
|--------------------|--------------------------|--------------------------|
| Hyena | Tyrannosaurus Rex | Rhinoceros |
| | Woolly Mammoth | Gorilla |
| | Smilodon (Saber-tooth) | Cheetah |
| | | Giraffe |

---

## 🧠 Explanation:

- Extinct = No living individuals remain (dinosaurs, mammoths, saber-tooth cats).
- Endangered = Facing high risk of extinction soon (rhinos, gorillas, cheetahs, giraffes — all have declining populations due to human activity).
- Non-Endangered = Stable populations, not currently at risk (hyenas are widespread and abundant).

> 💡 Teaching Tip: This worksheet simplifies complex conservation statuses. In reality, many animals fall into “Vulnerable” or “Near Threatened” categories — but for young learners, grouping into these 3 broad categories helps build foundational understanding.

✔ Final Answer Table:

| NON-ENDANGERED | EXTINCT | ENDANGERED |
|----------------|---------------------|------------------|
| Hyena | T-Rex | Rhinoceros |
| | Woolly Mammoth | Gorilla |
| | Saber-tooth Cat | Cheetah |
| | | Giraffe |

*(Note: If your curriculum requires strict IUCN categories, cheetah and giraffe should be labeled “Vulnerable,” but since that column doesn’t exist, “Endangered” is the closest fit.)*
