Problems, then questions, then knowledge
PQK Lab is an inquiry workshop, not a poster factory. This page keeps evidence habits on the trail from friction to knowledge. Insights are the lab's public field seminars. They do not introduce invented mentors or results. They teach a move until it can be attempted in a real setting.
Habits are not posters about evidence. They are pages with dates. For evidence habits, the lab's answer is inquiry-based STEM: notice a real problem, design a researchable question, gather evidence a peer could inspect, build a knowledge model, and only then communicate.
If evidence habits still lives at the level of a theme, PQK will not help a team jump to a showcase title. The sequence is the pedagogy. Problems, questions, knowledge.
The inquiry move this page trains
The habit here is notebooks that survive a visitor. Read with a notebook open. After each section, apply the move to evidence habits. If you cannot walk to a setting, the section is not finished.
Teams keep objects that make evidence habits visible: the search intent, the track move, the collapse, the object, the critique question, and the next track. Those objects are the curriculum. They are also the only honest rehearsal for a later science fair, design review, or classroom critique.
Mentors do not seize the build when the work is evidence habits. They ask for the trail. A visiting teacher should be able to follow the trail from the first noticing to the latest model without needing a speech.

- the critique question
- the next track
How inquiry quietly turns into display
PQK watches evidence habits fail in predictable ways. The failure is usually not a lack of enthusiasm. It is a missing problem, an untestable question, or a knowledge claim that arrived before the evidence log.
Repair is always a return to the trail. Redesigning the poster comes last. For evidence habits, PQK would rather keep an ugly notebook with a live question than a beautiful board with a dead one.
- using the essay as a citation instead of going to a setting
- inflating the problem because the essay is long
Problem framing for students
Problem framing is a craft, including when the work is evidence habits. Students learn to separate a grievance, a wish, and a problem that can be investigated. A grievance may be true and still too large. A wish may be kind and still untestable. A problem has a setting, a friction, and a possible observation.
From a framed problem, question design produces variants. Some variants are too broad. Some hide the answer. Some require a laboratory the team does not have. The surviving question is researchable because evidence could confirm or embarrass it. That is the PQK meaning of researchable questions in evidence habits.
Evidence habits then take over in evidence habits. Teams decide what they will count, photograph, measure, or trial, and how they will record a miss. Knowledge is not a paragraph of certainty. It is a model that can be revised when the next trial disagrees.
A field-scale worked example
Worked at PQK, evidence habits in stem always returns to a doorway, a lunch line, a planter, or a sensor the team can actually reach. The mentor asks what evidence could embarrass the current sentence. If the room cannot answer, the essay's advice has not yet become a habit. That is inquiry-based STEM: not a larger theme, a harder local question.
They then write five questions about evidence habits and strike three as untestable. The remaining two are compared by evidence cost. The cheaper honest question wins. An evidence log is opened before any prototype is glued.
After a week of observations on evidence habits the knowledge model is ugly and useful: two likely causes, one constraint, one uncertainty. The inquiry build tests one cause. The showcase draft is forced to include the miss. That sequence is inquiry-based STEM, not a storyboard of success.
Evidence, models, and builds
Read with a notebook open. After each section, apply the move to evidence habits. If you cannot walk to a setting, the section is not finished. An evidence log for evidence habits is dated, located, and unit-aware. A knowledge model names causes, constraints, and uncertainties. An inquiry build is a test, a prototype, a protocol, or a data story that tries the model in the world.
Showcase communication about evidence habits is last because communication should carry knowledge, not conceal its absence. A poster that cannot point to a log is advertising. A talk that cannot admit a failed trial is theatre.
A reader should finish evidence habits in stem with a more local, more testable next sentence.
Who uses this lab page
Students use it to see how evidence habits is supposed to feel in the hands: messy at first, then sharper. Families use it to support the trail without replacing the noticing. Schools use it to design inquiry clubs that do not collapse into craft hour.
Inquiry mentors use this page as a shared critique language for evidence habits: problem, question, evidence, model, build, communication. Learning partners use it to see how a challenge brief can stay student-scale.
PQK does not publish rankings, invent faculty celebrity, or quote unnamed testimonials about evidence habits. The lab's proof is the quality of questions and the inspectability of evidence.
What to do after reading
Return to the insights index or enter the matching track in the curriculum. An inquiry about evidence habits should include a real setting, a first-pass problem, any question already attempted, and constraints of time, tools, and school context.
If you need a track for evidence habits, open the curriculum. If you need a format, use offerings and the compare page. If you are a school, describe the club or unit the module would sit inside. If you are a family, say how much authorship the student can actually sustain.
The lab will answer evidence habits with a smaller question more often than with a larger plan. That is a compliment to the work.
Critique questions the lab keeps repeating
These questions are the mentor script for evidence habits. Teams should learn to ask them before anyone else does.
- Where, exactly, was the problem noticed?
- Which question could a two-week evidence log actually embarrass?
- What did you count, photograph, measure, or trial, and what did you skip?
- What rival explanation still fits the same observations?
- Which sentence on the poster is still a hope rather than a finding?
From local proof to transferable knowledge
Knowledge building in evidence habits does not require a universal law. It requires a model that another team could try in a neighboring setting. Transfer is earned by clarity of conditions, not by louder adjectives.
Students working on evidence habits learn to say what would have to be true for the model to fail elsewhere. That sentence is more scientific than a claim of global relevance.
PQK will not inflate evidence habits into a national verdict. It will help the team make a local study difficult to dismiss.
