Lesson aim
Evidence to collect
The learner separates measured findings, expert claims, and open questions in a science feature, and uses passive reporting and hedges to control certainty.
Language lens
Report findings with the right degree of certainty
A science feature must show what was measured, what experts believe, and what is still uncertain. Passive reporting structures foreground the finding or the belief, while hedges such as suggest, may, and tend to stop the writer from claiming more than the evidence shows.
Suggested sequence
Timing
- 3 min · Discuss heat, shade, and waiting outside in the learner’s city.
- 6 min · Read for the plan, the evidence, and the doubts.
- 5 min · Complete comprehension and point to the supporting line.
- 6 min · Sort sentences into finding, belief, and hedge.
- 3 min · Analyze how the writer balances experts and critics.
- 4–6 min · Explain the plan aloud or write a news brief.
Anticipated problems
Watch and respond
- The learner may treat every quoted statement as a proven fact; ask whether it was measured, believed, or predicted.
- The learner may produce forms such as trees believe to cool the air; drill be + past participle + to infinitive.
- Discussion can turn into a general debate about climate; bring it back to what this study did and did not show.
Short lesson
If time is limited
Read the first four paragraphs and Okafor’s final quotation, answer questions one, two, and five, and compare two passive reporting structures.
Extended lesson
If the learner needs more
Ask the learner to rewrite Okafor’s cautious statement as an overconfident headline, then explain exactly which words make it misleading.
Controlled practice
Answer key and teaching evidence
- shade-service · The city has decided to treat shade as basic infrastructure, like water pipes or streetlights, and to plant first where heat is worst.
- walk-more · Fewer households there own cars, so more people walk to bus stops during the hottest part of the day.
- old-decisions · Decisions made decades ago about highways and maintenance budgets are still visible in the canopy.
- water · Some council members describe water use as the project’s weakest point.
- health-effect · The study shows that shaded stops are much cooler, but not yet how much shade changes health across the whole population.
- wait-and-see · She will judge the plan by real shade at her stop, not by announcements.
- are-believed · Say Street trees are believed to lower air temperature.
- may-reduce · The findings suggest that shade may reduce heat stress matches what the study can support.
- members-described · Some council members described water use as the weakest point names the critics directly.
