When the Plan Has Never Been Challenged: Friction Framing, Science Years 4 to 6

Subject adaptation · Years 4 to 6 · Science · Field-Based STEM · Tony Jones

A prediction that has never been challenged is not yet thinking. Friction Framing gives the challenge a form and a moment: before the investigation begins, not after it is finished.

The Strategy

Friction Framing installs a structured challenge to the student's own first idea before any investigation begins. The challenge takes one sentence. The commitment takes one sentence. Together with the original prediction, they form a three-sentence artefact that records unassisted thinking before any external input arrives.

  1. Before any investigation, materials collection, or tool use begins, students write their prediction or plan in one sentence.
  2. Students identify the weakest assumption in their prediction and write it as a single sentence beginning: "The part of my thinking that could be wrong is..."
  3. Students commit in writing: accept the challenge and revise the prediction with a specific reason, or reject the challenge with a specific reason.
  4. The teacher collects all three sentences as a single artefact. Investigation materials are not distributed until this artefact is received.

In Practice

Years 4 to 5

Teacher selects the investigation context and models the friction statement process once before students attempt it independently. Students may draw their plan alongside the written sentence. Teacher scribes for students who need writing support, using the student's spoken words.

Years 5 to 6

Students select their friction statement from two teacher-provided options, then write their commitment independently. By Year 6, students write all three sentences without options, with the teacher circulating to prompt rather than model.

Implementation

Decision Checkpoint

Collect the three-sentence artefact before distributing investigation materials. If a student's friction statement describes a strength rather than a challenge, return it with one question: "What could make this plan not work?"

Teacher Judgement Note

Friction Framing works best when the teacher models it using a genuine scientific question where being wrong is genuinely possible. Avoid demonstration examples where the answer is already known to the class.
