Identifying Text Structure Assessment worksheet with three informational passages and corresponding text structure options.

Let's solve this "Identifying Text Structure Assessment" by analyzing each passage and determining its text structure. The four possible structures are:

- Sequence – steps in order (how to do something)
- Cause and Effect – one event leads to another
- Problem and Solution – a problem is presented, then a solution is offered
- Compare and Contrast – similarities and differences between two or more things

1. "Hunters of the Sea"

> Passage Summary:
This text discusses sharks and orcas. It highlights what they have in common (both are carnivores, have smooth bodies, sharp teeth) and how they differ (sharks are fish that lay eggs; orcas are mammals that give live birth and have bones).

> Analysis:
The passage clearly compares and contrasts two animals—sharks and orcas—by listing their similarities and differences.

> ✔ Text Structure: Compare and Contrast

2. "Volcanic Eruption!"

> Passage Summary:
This describes how to make a volcano erupt using baking soda, vinegar, food coloring, and dirt. It gives step-by-step instructions: set up the bottle, add ingredients, and pour vinegar to trigger the reaction.

> Analysis:
The text follows a clear step-by-step process for creating a science experiment. Each sentence builds on the previous one in chronological order.

> ✔ Text Structure: Sequence

3. "Disappearing Forests"

> Passage Summary:
It explains that people cut down trees for lumber and fuel. If trees are cut faster than they grow, it causes problems: animals lose homes, rain washes dirt into streams, new trees can’t grow, fish die, and forests become barren.

> Analysis:
The passage starts with a problem (trees being cut too fast), then explains the effects (loss of habitat, soil erosion, etc.). There is no proposed solution—just a chain of consequences.

> ✔ Text Structure: Cause and Effect

---

✔ Final Answers:

| Passage | Text Structure |
|--------|----------------|
| Hunters of the Sea | Compare and Contrast |
| Volcanic Eruption! | Sequence |
| Disappearing Forests | Cause and Effect |

📝 Explanation Summary:

- Compare and Contrast: Used when showing how things are alike and different.
- Sequence: Used when describing steps or events in order.
- Cause and Effect: Used when explaining why something happens and what results from it.
- Problem and Solution: Not used here because none of the passages offer a solution to the problem.
