Reading 1 — The Mystery of the Silent Pond

Part 1 of 2

For several summers, Willow Pond had been loud with frogs after sunset. This year, students from a nearby school noticed something strange: the pond was almost silent.��Their first guess was pollution. They tested the water for several common chemicals but found no unusual levels. Then they compared photographs from previous years. The pond had much less shallow water along its edges.

Part 2 of 2

A dry spring had lowered the water level. At the same time, thick plants had spread across parts of the shoreline. The students learned that several local frog species laid eggs in warm, shallow areas with open water.��They could not prove that one factor explained the silence. Still, the evidence suggested that changing habitat conditions were a stronger explanation than chemical pollution. The students recommended continued water testing and a survey of frog eggs the following spring.

Questions — The Mystery of the Silent Pond

Integrated Middle School Reading Skills

1. What is the central idea of the passage?

2. Which detail best supports the central idea?

3. What does an important word or phrase mean in context?

4. What can the reader infer?

5. How is the passage organized, or what is the author’s purpose?

Answer Guide — The Mystery of the Silent Pond

How to Solve

1. Suggested approach: Identify the idea developed across most or all paragraphs, not one isolated fact.

2. Suggested approach: Choose a concrete fact or event that directly strengthens the central idea.

3. Suggested approach: Use nearby words, examples, contrasts, and the paragraph topic.

4. Suggested approach: Combine a text clue with logical reasoning; the inference must be supported by the passage.

5. Suggested approach: Look for structure such as cause/effect, compare/contrast, sequence, problem/solution, or argument.

Reading 2 — The Experiment That Changed the Plan

Part 1 of 2

A robotics team wanted to build a small vehicle that could carry a cup of water across a rough surface without spilling it. Their first design used four hard plastic wheels.��During testing, the vehicle bounced sharply over every bump. The team tried driving more slowly, but the cup still lost water. One student suggested replacing the wheels with larger rubber tires.

Part 2 of 2

The new tires reduced some bouncing, but the vehicle became harder to steer. Instead of choosing one design immediately, the team measured the amount of water spilled and the time needed to complete the course for several wheel sizes.��The results surprised them. Medium rubber tires performed better overall than either the original wheels or the largest tires. The team changed its plan based on the data.

Think Deeper

Optional written response

Choose one passage. Write 4–6 sentences explaining one important idea from the text. Use at least two details as evidence.

Goal: Make a clear claim, cite evidence, and explain how the evidence supports your thinking.
