1: STORY

What happened?

The starter describes trees being removed during a stormwater-line repair. The three practice receipts document a different investigation: tree work beginning October 3, an arborist's risk assessment, and a replacement plan. No receipt identifies a stormwater project. The crew keeps the starter's explanation separate from documented reasons.

The parks notice says removal will occur across three blocks. It establishes planned action and a start date but does not identify each tree or explain the decision. Lupa resists filling that gap with the most visible explanation. An accurate notice can still leave questions about why and where.

The arborist assessment identifies twelve high-risk trees: eight scheduled for pruning and four for removal. Onda notices that high-risk does not mean all twelve will be cut down. The response differs within the assessed group. At the same time, the assessment is a technical basis, not a complete public explanation of every alternative, location, or effect on people using the blocks.

Nexo compares the replacement plan: six trees this fall and six next spring, selected for canopy and heat tolerance. Twelve new trees do not automatically provide twelve mature trees' shade right away. The supplied documents do not measure that timeline or explain how replacements relate to the four removals. Voz prepares questions that acknowledge risk, distinguish treatments, and investigate environmental consequences without assuming the plan erases every loss.

2: EVIDENCE

Open the receipts.

These are NPW practice documents. Real-world sources are credited separately below.

SOURCE A — Work notice

NPW practice document; parks department. “Tree removal on three blocks beginning Oct. 3.”

What it establishes: Establishes planned action, not the reason.

Question while reading: What source would explain the decision?

SOURCE B — Arborist assessment

NPW practice document. “12 trees rated high-risk due to structural failure; 8 scheduled for pruning; 4 for removal.”

What it establishes: Provides technical basis and distinguishes removal from pruning.

Question while reading: Which trees are actually being removed?

SOURCE C — Replanting plan

NPW practice document. “Replacement planting: 6 trees this fall; 6 next spring; species chosen for canopy and heat tolerance.”

What it establishes: Shows mitigation/replanting, not whether residents agree with the decision.

Question while reading: What tradeoff could students investigate?

Source A announces removal on three blocks beginning October 3, but gives no reason. Source B supplies a technical rationale and separates eight pruning treatments from four removals within twelve high-risk trees. It does not name the individual trees or demonstrate that all possible alternatives were assessed in the excerpt.

Source C describes twelve planned replacement plantings over two seasons and the species-selection goals. It does not prove those plantings have occurred, that they replace only these four removals, or that equivalent shade will return immediately. No supplied record establishes the starter's stormwater explanation. The next inquiry should connect tree locations, treatment reasons, and replacement outcomes.

Check the reasoning

Source B distinguishes treatments. Source C is a future planting plan and does not measure present or equivalent canopy.

4: TASK

Write three questions that separate environmental impact from rumor.

Write three questions that separate environmental impact from rumor. Include one clear claim or question, at least two source references, one statement of uncertainty/scope, the person or office with relevant authority, and one realistic next step.

Compare with a worked response

My three questions are: Which four assessed trees are scheduled for removal, and how do they correspond to the three-block notice (Source A; Source B)? What structural-risk findings support removal rather than pruning for those trees (Source B)? Where will the six fall and six spring replacements be planted, and how will the department evaluate canopy and heat benefits over time (Source C)? I would send these questions to the parks department and request the relevant tree map and arborist details. The receipts distinguish removal from pruning but do not establish immediate shade replacement, completed planting, or the starter's stormwater-repair explanation.

Before you close the case

  • What is one thing the strongest source establishes?
  • What can it not establish?
  • Who can decide or clarify the issue?
  • What changed between your first read and your read now?

One step further

If a school removes mature trees and promises new landscaping, what evidence would help compare immediate losses with expected benefits across several years?

Teaching moves

  • Ask students to represent twelve assessed trees with counters, separating eight pruning treatments from four removals before discussing replacement numbers.
  • Have pairs sort statements into planned action, technical rationale, expected mitigation, and missing outcome evidence.
  • Invite students to revise one accusatory question into a specific records question while preserving its legitimate concern about environmental impact.

Supports and response choices

  • Preview the three most important terms with examples.
  • Allow oral, typed, handwritten, or visual-map response when format is not the learning goal.
  • Keep the original source excerpt beside a plain-language annotation.
  • Keep formal English institutional terms visible beside translated explanation.
  • Advanced extension: compare the practice document with a real current local source.
