How science works
We open Section 2 by building a clear, precise understanding of the scientific method — not as a set of steps memorized in school, but as a living process of hypothesis, testing, revision, and consensus-building. Science is not simply a collection of facts; it is a way of generating and evaluating claims about the world. In this session you will develop the English vocabulary for talking about evidence, methodology, and the difference between a finding and a theory, and you will begin to see why how science works matters as much as what science has discovered.

Grammar focus
Grammar focus: The language of scientific hedging — "Studies suggest that..." / "The evidence indicates..." / "Current research points to..." / "It has been found that..." These passive and impersonal constructions are the backbone of academic and scientific English. They signal that a claim is grounded in evidence rather than personal belief, and they communicate appropriate uncertainty without undermining credibility. Noticing when a speaker uses these structures — versus when they should but don't — is a critical reading and listening skill.
Come prepared to discuss
"What is the difference between a scientific theory and a guess? Why do you think many people use the word 'theory' to mean 'just an idea'?"
Before this session
Prepare: Find one recent science news headline — in any area you find interesting. Read the headline and the first two paragraphs. Ask yourself: Is this a preliminary finding or an established consensus? What language in the article signals that? Come ready to share the headline and what you noticed about how the claim is framed.
Task-Based Activity
Present students with five claims ranging from "well-established scientific consensus" to "preliminary single study" to "popular myth dressed as science." Students work in pairs to rank the claims by reliability and explain their reasoning using this session's vocabulary. Debrief: What made a claim trustworthy? What red flags did you spot? Follow up with a short discussion: Is all science equally reliable — and how do you tell the difference?
Career-Oriented Take — How to Frame It
In any data-driven workplace — finance, healthcare, tech, policy — the ability to read a finding critically and express appropriate confidence or skepticism is essential. "Studies suggest" and "the evidence is inconclusive" are not evasions; they are marks of intellectual honesty that signal professional credibility. Students who can use scientific hedging language accurately will communicate more persuasively in high-stakes professional environments.
Big Picture — Global Context
The scientific method is one of humanity's most powerful tools for reducing error and self-deception. It is not perfect — science has been wrong, biased, and misused — but it is the best system humans have developed for systematically correcting mistakes. Understanding how it works is not just an academic exercise: it is the foundation for participating in public debates about climate, health, technology, and policy that will define the next generation.
Homework (assign after session)
Find a science news story that includes a link to or mention of the original study. Compare how the news article describes the findings versus how the study's abstract presents them. Are there differences? Does the headline overstate the findings? Write 3 to 5 sentences on what you notice. Bring it to Session 6.
