Interactive Replace (IR) sits at the Interactive row and Replace column of the PICRAT grid. Below: real Science lessons for KS3 that classify as IR, plus anti-examples that look IR but are not.

Drag-and-drop labelling of a cell organelle diagram

Year 8 · 30 min · 1 device per student

Each student drags labels onto a digital cell diagram, matching each label (nucleus, mitochondrion, ribosome, etc.) to its organelle. After submission, the tool reveals correct positions.

Multiple-choice cell-structure quiz on Microsoft Forms

Year 8 · 25 min · 1 device per student

Students answer ten multiple-choice questions on cell organelle functions in a Microsoft Form. Each pupil sees the same ten questions in the same order. The teacher reviews aggregate results in the next lesson.

Building atoms by dragging electrons in a chemistry simulator

Year 9 · 30 min · 1 device per student

Students drag electrons onto an atomic structure diagram for the first ten elements. They submit a screenshot of each correctly-built atom to the teacher. The simulator does not give in-line corrective feedback; it just renders what they place.
