Real optics: the field shrinks as you go up, the depth of field collapses, and the 100x is useless without its drop of oil.

Class 9-12120 slidesMeasure in um

Grow one plant a day at a time — wake the seed, rescue a leggy seedling with light, keep the soil in the band, pick the soil, feed the yellow leaves, bend it to the lamp, bring it to flower with long nights, pinch it bushy, run a fair test, take a seed to fruit — and keep one that remembers you while you are away

🌱

On the sill

Plant Lab

A daily-step pot model: soil water as a fraction of capacity with drainage above field capacity by soil type and absolute evapotranspiration from leaf area, light and heat; germination on moist warm days; light-limited sugar production feeding height and leaf area under a pot-limited ceiling; etiolation, chlorosis, wilting and root rot as state; phototropic lean with pot rotation; a short-day photoperiod flowering rule and fruit set; a fair-test checker; and a persistent plant advanced on the real clock between sessions.

Build the Punnett square by hand, then breed litters drawn one gamete at a time and see whether your ratio comes true — a test cross, six pups against four hundred, pink flowers, blood groups, a dihybrid, eye colour on the X, a pedigree, linked genes and map units, and a chi-square verdict

🐭

Breeding bench

Heredity Lab

Gametes enumerated per locus with probabilities, linked loci in coupling or repulsion with a recombination fraction, a Punnett square as the outer product, phenotypes by dominance, blending, codominance, X-linkage and a lethal; litters drawn by seeded random gamete sampling with lethal loss; tallies, deviation, recombinant fraction and a chi-square against expected shares; a pedigree whose inferable genotypes are derived from real ones.

Class 9-1210 crossesDrawn, not dealt

A dry forest of eight species as a web that is also equations: draw who eats whom, pull the leopard and watch the deer and then the grass, run a drought, find the keystone, loose lantana and control it, measure a carrying capacity, follow a toxin up the chain, read the monsoon pulse, and rebuild a collapsed web

🐆

Pull a thread

The Ecosystem

Eight-species food web with logistic producers under seasonal forcing and a drought factor, Holling type II consumers with diet preferences, trophic efficiency, mortality and self-crowding, stepped monthly in sub-steps; removals, reintroductions, an invasive competitor with a control; trophic pyramid, keystone search by secondary extinctions, carrying capacity with overshoot, toxin concentration by diet and efficiency, calendar-month peaks and a stability index — all measured against the untouched forest.

Nine systems coupled into one body: hold your breath, stop the heart, skip the meals, stop the kidneys, cut the brainstem, run hard with the drive off, fight a fever, lose the marrow, eat without insulin — and read what stopped, in what order, and when

🫀

Throw a switch

Body Systems

A coupled physiology stepped per minute: ventilation gated by brainstem drive, muscle and energy; oxygen and CO₂ against supply and activity demand; gut absorption, insulin-gated uptake, liver glycogen and a fasting floor; urea production and renal clearance; heat balance with fever set-point; infection growth against immune killing; marrow production against red-cell lifetime; energy from oxygen, fuel and pumping; a brain with thresholds — and a timeline of when each part stopped.

Culture a population that lags, doubles and starves; count it by dilution and plating; sterilise a spore and pasteurise milk by D-values; find the antibiotic dose, finish the course, watch one resistant cell take over an under-dosed wound, clear it with two drugs, wash your hands properly, and run a ward for thirty days

🦠

Culture bench

Microbe Lab

Susceptible and resistant populations with lag, logistic growth on depletable nutrient, whole-cell mutation from accumulated divisions and a fitness cost; Hill-type antibiotic kill above strain MICs with first-order drug decay and eight-hourly dosing; host nutrient replenishment and immune clearance; Poisson plate counts with dilution; D- and z-value heat kill for a vegetative cell and a spore; log-reduction hand-washing; and a thirty-day ward whose failures seed later arrivals unless isolated.

Class 8-1210 benchesResistance, measured

A flock with real genes: breed the deepest beaks and read heritability off the chicks, eat the moths you notice, run a drought until the response runs out of genes, watch stabilising selection tighten the breeders, split a flock across two niches, see luck fix an allele in ten birds, draw eight founders, find the recessive that never leaves, reunite two islands, and chase the bark through the soot years

🐦

Ten islands

Evolution Lab

Individual-based population genetics: sixteen additive diploid trait loci plus a marker locus, environmental noise, fitness-proportional parent draws, Mendelian segregation with per-copy mutation, optional assortative mate choice among six suitors, and frequency-dependent two-niche payoffs. Heritability is read as R/S from truncation breeding and checked against Va/Vp counted from the birds; stabilising, directional and disruptive selection, drift at N = 10 versus 1000, founder draws, mutation-selection balance for a harmful recessive, island divergence and reunion, and a moving-background melanism run are all measured from the stepped generations.

Class 9-1210 islandsGenes, counted

Paint a week of sleep, plates, water and play and let one body live it five minutes at a time: sleep debt that fogs Friday, a screen that keeps you awake in the dark, the mid-morning slide without breakfast, the sugar crash, a heatwave on three glasses, stamina, a cold going round, a homework mountain, a growing body — and six dials scored from the week you lived

🍎

Week planner

Health Lab

A paintable 7×24 timetable, four plates and a water count driven through a five-minute physiological trace: two-process sleep pressure with a carried sleep debt and light-delayed onset, gut absorption at each plate's rate cap and time constant, a lagged insulin response with rate-of-rise sensitivity, liver glycogen with gluconeogenic fallback, hourly water losses with kidney conservation and thirst-driven drinking, MET-based energy expenditure, and nightly stamina, stress, immune-defence and mood tallies with a Wednesday germ exposure. Every readout and all six dials are measured from the traced week.

Class 6-1010 weeksLived, not ticked

Run a hectare a day at a time with only a three-day forecast: sow on the rain, bank the water, split the nitrogen before the rains leach it, weed in the critical weeks, count pests and their enemies before you spray, cut before the shower, keep the soil over three seasons, live ten monsoons at once, and make a season pay — every loss measured by replaying your own season without it

🌾

One hectare

Farm Lab

A daily crop model run live against seeded season weather with an 80 %-reliable three-day forecast: growing-degree-day phenology with dry-sown seed that waits for moisture and seedlings that die in a false start, radiation-use growth over a canopy-cover light interception, a root-zone water balance with soil-specific field capacity, drainage and runoff, a leached and mineralised nitrogen pool, logistic weeds suppressed under a closed canopy, pest–enemy dynamics with a seeded pressure and a seasonal window, waterlogging damage, post-maturity drying, shattering and rain losses, and per-hectare economics. Losses to weeds, pests and nitrogen are measured by replaying the student's own action log with each factor switched off; ten-year and three-season scenes run the same model by rule.

Drawn by lot at dawn, you live one Athenian civic day forward holding the objects themselves — and a vote you miss stays missed

🏛️

Virtual tour

Agora

You are drawn by lot at dawn and hold one Athenian civic day in your own hands - bronze pinakion, juror's staff, the secret ballot, the ostrakon. The day only runs forwards, so the one way to meet a case again is to wake and be drawn again.

Citizen for a daySortition by lotNo rewind

Sit on the bench: rule on evidence, cross-examine a witness and watch her word lose weight, read the scales of proof that start from innocence, decide the same facts as a claim and as a crime, grant bail by the rule, pass a proportionate sentence, and write a judgment that must justify itself

Law & Society

A case tried properly, and a town prepared for the disaster it then lives through

⚖️

On the bench

The Courtroom

Evidence as items with a kind, an admissibility rule and a likelihood ratio; a posterior of guilt multiplied from prior odds over admitted items, each weakened by cross-examination effects; standards of proof by case type; a ten-stage procedure order, an Article 20–22 rights list, a bail rule (bailable → right; else flight, tampering or grave-and-strong), a proportional sentencing range from base × factors, and a judgment checker that rejects reliance on excluded evidence, the wrong standard or a finding the scales do not support.

Class 9-1210 mattersScales that multiply

Prepare a riverside town on a budget — embankment, drains, siren, drill, shelter, retrofits, pucca houses, relief — then live through the fifty-year flood and the magnitude-7 quake and be judged on casualties, damage and school days, computed from the town as it stood against the town that did nothing

🌊

Town planner

Disaster Lab

A 5 × 5 town with elevations, occupancies and values; river stage against embankment height and block elevation, rain against drain capacity; depth–fatality and depth–damage functions, evacuation from lead time against drill-shortened evacuation time, shelter dryness and reach; PGA attenuation and lognormal fragility by building class with retrofit medians; occupancy by time of day; relief person-days from affected × days flooded — every outcome run against the unprepared baseline.

Class 6-1210 tasksLive through it

Run a real stove: bring water to the boil and read the plateau, seal a cooker for dal, take the egg out before the yolk sets, brown paneer without burning it, split milk with lemon, keep the vitamin in the spinach, rise a dough, beat the danger zone, pour caramel in its window, and build a thali that meets a thirteen-year-old's needs

Home Science

A stove that is stepped every second, and fibre that becomes fabric

🍳

On the stove

Kitchen Lab

A three-node thermal model (pot and water, food surface, food core) with latent-heat boiling pinned at a pressure- and sugar-dependent boiling point, surface-moisture-gated Maillard kinetics, Q10 starch and protein cooking, egg-white and yolk set points with carry-over, casein coagulation below pH 4.6 in hot milk, first-order vitamin C decay plus leaching, a yeast rate curve with a death temperature, temperature-dependent bacterial doubling, syrup boiling-point elevation, and a plate builder on per-serving nutrient values.

Class 6-1210 dishesStepped every second

Spin a yarn and break it, weave a cloth on a loom that jams when yarns touch, dye it with a class that bonds or does not, and test what you made — strength, tear, breathability, warmth, drape, the drop test, the wash, the flame — every number computed from fibre, twist, sett and weave

🧵

At the loom

Textile Studio

Seven fibres with tenacity, elongation, regain, crimp, lustre, stiffness, shrink and wrinkle parameters plus dye-class affinities and burn behaviour; a twist-multiplier utilisation curve for yarn strength; weave-dependent jamming, tensile, tear-sharing, bending and thickness factors; cover-factor breathability, trapped-air warmth, regain-driven absorbency, relaxation shrinkage, fastness-driven wash fading — a testing bench that computes every property from the construction.

Class 6-1210 piecesNothing looked up

Ten classic experiments run on yourself — reaction and decision time, Stroop, memory span, the serial-position curve, an illusion measured by adjustment, the attention cue, anchoring, mirror tracing, a Weber staircase — with a notebook that computes exactly what your own trials show

Psychology

Classic experiments run on yourself, and growing up seen from inside each age

🧠

Subject: you

The Mind Lab

Millisecond-timed trial machines for simple, choice, Stroop and Posner tasks with anticipation and lapse exclusion; an adaptive digit-span staircase; free-recall serial-position scoring by thirds; method-of-adjustment illusion measurement; log-ratio anchoring analysis; mirror-tracing with slip counting; and a one-up two-down staircase for the JND at two standards — all statistics computed live from the student's own data.

Class 11-1210 experimentsYour own data

Turn the age dial and meet the classic tasks as a child of that age meets them — the hidden toy, the poured water, Sally's marble, 'goed' and 'went', Heinz's dilemma, the Strange Situation, friends at the yellow light — then ask a hundred children and find every transition age yourself

🧒

Age dial

Growing Up

Logistic age curves for A-not-B search, liquid conservation, false belief and perspective taking; a U-shaped overregularization curve; softmax Kohlberg level shares; Ainsworth reunion behaviours with a classification rule; Steinberg's peer effect; age-weighted self-description categories — every readout a seeded cohort drawn from the curve, so transition ages are measured by the student, and the timeline is assembled from those same curves.

Class 9-1210 stagesCohorts, not quotes

One honest flight model for every game — drag, Magnus bend, bounce — and the rules as geometry: clear the rope, drop a free throw, curl a free kick over the wall, swing off the seam, judge leg before and offside, beat the keeper, and find the long jump's best angle

Physical Education

The physics of a game from where the player stands, a body that trains, a breath that goes with the pose

🏏

Player's eye

Sports Lab

A 3-D ball-flight integrator with quadratic drag, Magnus lift from a spin vector and a bounce model, shared by cricket, football, basketball and athletics; rules as geometry — six, hoop, wall and goal, leg before, offside, penalty reach — and a long-jump model that trades run for lift; optima found by flying, not by formula.

Class 6-1210 activitiesThe air is real

Drive a treadmill against a living body — a heart that lags the belt, lactate past the threshold, a tank that empties, sweat that dries you out, muscles that warm — then plan the weeks: taper to peak on race day, and lift, rest, grow

🏃

Coach's clipboard

Fitness Lab

A body stepped one second at a time: first-order heart-rate lag with a post-exercise floor, exponential lactate above a threshold with a sourness integrator that makes the legs give, glycogen burned as the square of demand, sweat and cardiac drift, muscle temperature and a sprint that depends on it; a Banister fitness–fatigue block and a stress–recover–grow strength model. Every readout comes from the trace.

Class 6-1210 activitiesNothing is looked up

Drag a body with real masses into eight asanas and let its own mechanics judge you — joint angles, the stack of ear over hip over ankle, the centre of mass over the feet, a floor that is wherever the lowest point rests — then breathe with it and find the breath that swings the heart

🧘

On the mat

Yoga Studio

A sagittal chain of thirteen segments with Dempster masses and joint limits, posed by dragging; forward kinematics, the floor as the lowest point, contacts, a centre of mass and its margin over the base of support; eight asanas as lists of measured checks, a breath-driven resonant heart-rate model (RSA peaking near six a minute), and a sun-salutation breath rule derived from each pose's measured chest openness.

Class 4-1210 activitiesJudged by mechanics

Throw a pot from rings of clay that keep their volume: too thin folds, too wet slumps, too fast flares the rim — centre, open, pull, belly, half a litre, dry, and fire, where wet bursts, uneven cracks and sound work shrinks a tenth, for good

Art & Design

Paint that runs, clay that slumps, briefs that must be met

🏺

Wheel head

Pottery Wheel

A pot as 24 rings with height, radius and wall thickness under volume conservation; a collapse rule against wall thickness and height above, a load-over-strength slump rule that weakens with water, centrifugal rim flare, drying, and a kiln that bursts wet clay, cracks uneven walls and shrinks sound work by a tenth; capacity integrated from the hollow.

Class 6-1010 activitiesFiring is final

Composition, type and colour judged by measurement: contrast by the luminance formula, hierarchy as a ratio, alignment as shared edges, margins, whitespace, balance, the rule of thirds, line length, a palette in degrees — meet each brief, then the whole one

📐

Layout table

Design Studio

Rectangles on a 600×800 sheet measured for WCAG contrast, type-size hierarchy, shared edges and centre lines, margins, sampled whitespace, a luminance-weighted centroid, distance to rule-of-thirds crossings, characters per line, hue palettes and harmony, overlap and containment; ten briefs verified to fail as given and pass with a model layout.

Class 8-1210 briefsTaste, measured

Paper that behaves: wet-on-wet blooms, dry brush that stays put, drips down a tilted board, colour mixed on the sheet or layered once it dries, charcoal rubbed into shadow, wax that refuses a wash, a graded sky, glazing — every spread and hue read off the grid

🎨

Wet paper

Art Studio

A 160×120 cell model of paper: water spreading to drier neighbours and carrying pigment, pigment drifting through standing water, downhill runs past the paper's holding capacity, evaporation fixing pigment, surface charcoal moved only by rubbing, wax blocking water; subtractive RYB colour; spread radius, run length, mixing, hue, darkness and smoothness measured on the grid.

Class 4-1210 activitiesMedia that behave

Edit a draft and watch a reader spend attention on it: cut the fat, split the sentence that runs out of air, vary the rhythm, say who did it, silence the echoes, lead with the point, hold the thread, get the reader to the end, then meet a whole brief

Language

Sounds that become letters, words that join and change, writing that shows its effect

✒️

Reader's desk

The Writing Room

Text analytics counted from the draft as it stands — sentence splitting, a syllable counter, Flesch reading ease, a passive-voice detector, adverb and echo counts, adjacent-sentence cohesion, the topic sentence by shared words — and a reader model that spends attention word by word and gives up when it runs out; ten drafts with a brief each, all verified solvable.

Class 6-1210 activitiesEvery edit measured

An agreement machine: build words from matras, then set gender, number, tense and ने on wheels and see what must agree with what — plurals, obliques, adjectives, present and future verbs, and the past that follows the object

🪔

Agreement machine

Hindi Lab

Stems and rules only: plurals and obliques from gender and ending class, marked adjectives, habitual and future conjugation with auxiliaries, perfective participles with vowel- and consonant-stem shapes and irregular जाना, the ergative ने with object agreement; student choices assembled and held against the rule-built sentence.

Class 4-1010 activitiesBuilt, not memorised

A joining bench: push two pieces together and the seam changes by rule — savarṇa-dīrgha, guṇa, vṛddhi, yaṇ, visarga, t and m — named in Sanskrit and written in Devanagari afterwards; decline rāma ending by ending, ṇatva and all, and build a sentence seam by seam

🕉️

Joining bench

Sanskrit Lab

Words as IAST sound strings; external and internal sandhi applied at the seam by rule (savarṇa-dīrgha, guṇa, vṛddhi, yaṇ, pūrvarūpa, ayādi, visarga, ścutva, jaśtva, anusvāra), ṇatva through the word, a-stem declension derived from stem + ending pieces, and a Devanagari writer that renders results rather than looking them up.

Class 6-1210 activitiesSeams that change by rule

A sound machine that makes every sound from scratch and an ear that turns sounds — the keys' or your own voice's — into letters: press, blend, say sss and mmm, find first sounds, make word families, count sounds, meet sh, write what you hear

🔤

Sound machine

Sounds & Letters

Formant and noise synthesis for fourteen English sounds, an FFT ear measuring level, voicing, spectral centroid and the first two resonances, tuned to the machine's own vowels; microphone input classified live; blending as timed cues.

Class 1-410 activitiesYour voice, in letters

Three friends, ₹15 lakh and an app, a month at a time: a funnel you can read, adverts against runway, a leaky bucket, a price test, unit economics, default alive or dead, an investor who prices traction, and a market shock that asks for a pivot

Commerce

Books that must balance, firms that must survive, markets made of many hands

🚀

Founders' desk

The Startup

A monthly funnel model — organic and saturating paid visitors, price-dependent sign-up, quality-dependent conversion and churn, referral, a decaying product — with runway, break-even, default-alive, CAC, LTV, an investor's disclosed valuation rule and a market shock with a pivot, all measured by running the months forward.

Class 9-1210 activitiesCustomers vs runway

Two levers, three dials, and the lags between them: cool an overheating economy, weigh an oil shock, spend out of a slump and mind the debt, break entrenched inflation, hit the zero floor, and write a rule that beats a fixed rate through five noisy years

🏦

Policy desk

The Economy

A quarterly macro model with a two-quarter rate lag and a one-quarter spending lag, a Phillips curve with adaptive, half-anchored expectations, Okun's law, public debt, a zero lower bound and seeded shocks; a squared-deviation loss, sacrifice and on-target quarters are summed from the model's own states.

Class 11-1210 activitiesLags you can feel

Sixty buyers, forty growers, one price board: count who steps forward and you have demand and supply — find the clearing price, let an auctioneer find it, then tax, cap, floor, shift and monopolise the pit and count what each does

🍅

Trading pit

The Market

An agent market: sixty buyers with private values, forty growers with private costs. Demand and supply are head-counts at each price; the clearing price, a tâtonnement auctioneer, tax incidence, shortages under a ceiling, surpluses under a floor, arc elasticity and a monopolist's deadweight loss are all counted from the agents.

Class 11-1210 activitiesNo curve was drawn

Run a small factory for a month on a cash calendar: fixed and variable costs, break-even, the price that earns most — then survive the month a profitable plan runs out of cash, with credit terms, an overdraft, a machine, overtime and a supplier shock

🏭

Factory floor

The Firm

A thirty-day simulation with rent, Friday wages, materials on supplier credit, sales on customer credit, capacity and overtime, an overdraft with interest and a mid-month materials shock; accrual profit beside the nightly bank balance; every optimum found by re-running the month.

Class 11-1210 activitiesCash is not profit

Double entry on a brass balance: journalise, post, place the trial balance so the beam sits level, then catch the error that tips it, the one that never does, and the two that cancel — and close the books to a profit the sheet will only accept if true

⚖️

Counting house

The Ledger

A month of real transactions posted to a ledger; the beam's tilt is computed from the two pans' totals, never from an answer key. Wrong-side, wrong-account and compensating faults injected into the books; gross and net profit and a balance sheet closed from the postings.

Class 11-1210 activitiesTrial balance you can feel

Place value as a machine — ten beads in any room collapse into one in the next, and carrying stops being a rule
