Passive Transform sits at the Passive row and the Transform column of the PICRAT grid. Students are watching or listening, and what they are shown could not be shown any other way.
Much of this cell is about time and scale. Year 7 watch a five-day time-lapse of their own copper sulfate crystals growing. Year 8 watch four decades of Amazon deforestation in Google Earth Timelapse. Year 8 watch the lunar eclipse Columbus foretold over Jamaica in 1504, recreated in Stellarium.
Some of it makes the invisible visible or audible: a phone magnetometer tracing a bar magnet's field, the harmonics of a single note on a live spectrum, the 1665 plague heard week by week from the London Bills of Mortality.
This cell is a useful corrective to the idea that Passive means weak. Students do nothing but look and listen, and the lesson is one no earlier teacher could have taught.
The teacher plays a time-lapse of one clear day filmed from the art room window, and students watch the colour of the light and shadows shift before comparing them with Monet's Rouen Cathedral series.
The teacher pours thinned paint from a stick in three different gestures while a tablet films in slow motion, and students watch the replays to see how the speed of the hand decides the mark.
The teacher runs Copilot on the board, asking the same questions in fresh chats and following its cited links, while students record what changes and what holds, then connect it to how language models predict text.
The teacher films pairs performing a rehearsed non-contact slap in slow motion from the audience's position and from the side, then replays the clips so the class sees how the illusion works.
The teacher films drop-weight impact tests on strips the class cut and notched, in slow motion, and replays them so students can see how each polymer fails.
The teacher plays nearly four decades of Google Earth Timelapse imagery of Alaska's Columbia Glacier, and Grade 6 turn what they watched into the evidence paragraph of a persuasive speech.
Grade 7 watch Chrome Music Lab's Spectrogram draw the teacher's voice reading two lines of Owen's 'Anthem for Doomed Youth', one showing as short broken patches of sound and the other as long drawn-out ones.
The class watches a time-lapse of their own water-cycle bag, taped to a sunny window and filmed by a school tablet across a whole school day, as droplets form, grow and run back down.
The teacher shows Windy's animated wind, pressure and rain layers for a real depression approaching the UK, and Grade 7 watch the air spiral into the low.
The teacher shows near-real-time ocean currents and sea surface temperatures on earth.nullschool, following the Gulf Stream from Florida to the North Atlantic Drift off Ireland, while the class compares Britain with Labrador on the same latitude.
The teacher plays nearly four decades of Timelapse imagery of the Ucayali River in Google Earth, and students watch meander loops creep sideways, pinch together and leave ox-bow lakes behind.
The teacher sets earth.nullschool to early September 2019 and steps Hurricane Dorian forward a day at a time, showing its winds and then the sea temperatures beneath it, while students watch the storm sit over warm water and loosen over cooler seas.
In a morning lesson the teacher opens Flightradar24 on the board, and students watch aircraft converge on London from North America, Asia and Africa as evidence of the UK's links with the wider world.
Grade 7 work a twenty-minute shift as craft workers or on five-step production lines, every student at a station, then watch the overhead time-lapse paused at two-minute marks to count the queue at each station.
The teacher plays a Sonic Pi sonification of the 1665 London Bills of Mortality, one bar per week and one click for every hundred plague deaths, and the class listens to the epidemic build and fade before reading Pepys.
The teacher sets Stellarium to St Ann's Bay, Jamaica, on the evening of 29 February 1504 and runs time forward so the class watches the eclipsed Moon rise, then tests Ferdinand Columbus's account of how his father used it.
The teacher plays a Sonic Pi piece in which every British and German dreadnought entering service from 1906 to August 1914 sounds as a bell, and Grade 8 judge what the naval race looked like from Britain in 1909.
The teacher plays Google Earth's Timelapse over central Berlin from 1984, and students watch the empty ground where the border cut through Potsdamer Platz persist, then fill with building sites and new blocks through the 1990s.
The teacher runs a whole lunar month over the school's town in Stellarium in two minutes, stopping at every eighth of the cycle, and Grade 3 name the fractions and find that the 'first quarter' Moon is 2/8 of the way round.
Grade 4 watch slow-motion footage of a litre of water spreading over their chalked metre square, paused by the teacher at each half second so they can count squares and estimate the area as it grows.
The teacher plays a swanee whistle, chime bars and a drum into Chrome Music Lab's Spectrogram, and the class watches the sounds appear on the board as rising, falling and smudged shapes.
The same A is played on a tuning fork, a flute, a violin and sung, while a phone running phyphox streams a live spectrum to the board and the class watches each timbre appear as a different pattern of harmonics.
The teacher plays a Huun-Huur-Tu track into Chrome Music Lab's Spectrogram, and the class watches a bright overtone melody step up and down above the singer's drone before they can hear it.
The PE teacher wears a chest-strap heart-rate monitor linked to phyphox and does a three-minute step test while the class watches the live graph climb, level off and fall on the board.
A school tablet time-lapses two weeks of sealed bread slices touched with unwashed, water-rinsed and soap-washed hands, and Grade 4 watch the mould appear and spread in under a minute.
Grade 3 watch slow-motion footage of dry sand and water poured side by side by two of their classmates, seeing separate grains bounce and heap up while the water breaks into drops, joins up again and settles flat.
The class watches a time-lapse, filmed by a school tablet over five days, of the copper sulfate solutions they set out to evaporate, as crystals appear and grow.
A tablet films the class's potassium permanganate beaker overnight in time-lapse, and Grade 6 watch hours of diffusion in under a minute and measure the spread.
Grade 7 watch a 48-hour time-lapse of their own hydrogencarbonate indicator tubes turning purple under the lamp and yellow in the dark, played and paused by the teacher.
A school tablet films the teacher's lithium, sodium and potassium demonstration in slow motion, and Grade 8 watch the replays on the board to record what the eye missed.
The teacher slides a bar magnet along a metre rule towards a phone running phyphox, and the class watches the strength of a field they cannot see rise, fall away and reverse on the board.
The teacher plays two days of time-lapse footage of one of the class's own agar plates, and students watch a bacterial lawn spread while the rings around the strongest antiseptics never cloud.
A technician carries a phone running phyphox up the school stairwell while the class watches the air pressure reading step down, landing by landing, on the board.
Children put frozen ice hands in sun and in shade side by side, a tablet films the trays in time-lapse all morning, and after lunch the class watches the whole melt in two minutes on the board.
Open Generate, pick a subject and an age range, and you will get a full 3x3 matrix of nine lesson ideas in under a minute. Passive Transform is one of the nine.
