Educational worksheet teaching students to identify the four kinds of sentences using blue whale facts.

Let's solve this step-by-step. The task is to identify the type of sentence for each of the 15 sentences listed. There are four kinds of sentences:

1. Declarative – makes a statement or gives information (ends with a period).
2. Interrogative – asks a question (ends with a question mark).
3. Imperative – gives a command or request (often ends with a period, but can end with an exclamation mark).
4. Exclamatory – expresses strong emotion or surprise (ends with an exclamation mark).

Now let’s go through each sentence:

---

1. The blue whale is the largest animal.
→ This is a statement.
✔ Declarative

2. It is bigger than thirty elephants.
→ This is a statement.
✔ Declarative

3. How much does it eat every day?
→ This is a question.
✔ Interrogative

4. It eats from four to eight tons of food a day.
→ This is a statement.
✔ Declarative

5. What a huge appetite it has!
→ This expresses excitement or surprise.
✔ Exclamatory

6. Blue whales are so gigantic!
→ This expresses strong feeling.
✔ Exclamatory

7. Does it really weigh 100 tons?
→ This is a question.
✔ Interrogative

8. The Antarctic blue whale weighs up to 150 tons!
→ This is a statement, but ends with an exclamation mark due to emphasis.
Even though it ends with an exclamation, it's still making a factual claim, so it's exclamatory because of the emotional tone and punctuation.
✔ Exclamatory

9. It spends six months a year feeding in Antarctic waters.
→ This is a statement.
✔ Declarative

10. A blue whale is about twenty-five feet long at birth.
→ This is a statement.
✔ Declarative

11. What a big baby that is!
→ Expresses surprise or admiration.
✔ Exclamatory

12. How much does a baby blue whale weigh?
→ This is a question.
✔ Interrogative

13. Please read the sign to find out.
→ This is a polite request/command.
✔ Imperative

14. It weighs about two tons at birth.
