Passive Replace sits at the Passive row and Replace column of the PICRAT grid. Below: real Science lessons for middle school (KS3, Years 7 to 9, ages 11 to 14) that sit in Passive Replace, plus anti-examples that look like it but sit elsewhere.
Grade 6 watch the technician's Bunsen burner safety video before a combustion practical
Year 7 are about to burn small samples of three fuels on heatproof mats and compare their flames, and department policy is that every class sees the full safety briefing before any flame is lit. The teacher plays the five-minute video the science technician made, embedded in the lesson's PowerPoint: tying back hair, goggles on, where the gas tap sits, lighting the Bunsen burner with the air hole closed, and what to do if a sleeve or hair catches. Afterwards the teacher questions the class out loud, cold-calling at least one student on each of the eight safety rules, and anyone unsure goes through that step again with the teacher at the front bench while the rest set up. Students sign the practical safety checklist in their books before collecting equipment.

Photosynthesis: follow the slide story of Priestley's mint, mouse and candle
Year 8 are starting photosynthesis, and the teacher opens with how scientists first found out that plants change the air. A slide deck tells the story in pictures: Joseph Priestley's 1771 experiment, in which a candle burning in a sealed jar went out and a sprig of mint left in that air for several days 'restored' it so a candle would burn again, then his mouse that survived in air a plant had restored, and Jan Ingenhousz's 1779 finding that plants restore air when they are in light and that it is the green parts that do it. Before each result appears, the teacher asks the class to predict what happened, and students write their prediction and then the result in their books. The lesson ends with students writing the word equation, carbon dioxide + water → glucose + oxygen, with light and chlorophyll above the arrow, and labelling which parts of it each experiment gave evidence for.

Grade 7 cover-and-recall self-quiz on a cells and microscopy knowledge organiser
Year 8 are halfway through their cells and microscopy unit, with an assessment in two weeks. The teacher shares the unit knowledge organiser as a view-only Google Doc: 15 keywords such as nucleus, cell membrane, mitochondria, chloroplast, cell wall and magnification in the left column, with definitions on the right. Students open it on their iPads, cover the definitions column with a card bookmark, write each definition in their books from memory, then uncover it and tick or correct their answer. After three rounds the doc is closed and students write five definitions from memory as an exit ticket, which the teacher collects to spot shared misconceptions.

Grade 8 read an atomic structure chapter on iPads and make notes before a test
Year 9 are revising for an end-of-unit chemistry assessment. The teacher shares a four-page chapter as a view-only Google Doc covering protons, neutrons and electrons, their relative masses and charges, atomic number, mass number and isotopes. Students read at their own pace on their iPads for 25 minutes, making notes in their exercise books as they go rather than annotating on screen. The teacher then closes the doc on the projector and sets six short-answer questions on the board, such as working out the number of neutrons in chlorine-37, which students answer in their books before marking them together.
