Kitchen Chemistry
Fizzing, curdling and colour changes with things from the grocery store. Students gather evidence of new substances, weigh a reaction in a sealed bottle, and turn red cabbage into an acid detector.

Grade 8 science lessons
Every unit and lesson for Grade 8, each a real question your class tests with everyday materials. Same class as Year 9 in the UK, Year 8 in Australia, Second Year in Ireland, Year 9 in New Zealand, Grade 8 in South Africa, Class 8 in India.
Science
Forces and Motion: Crash, Push and Stop
Why you lurch forward when the bus brakes, how fast a toy car really goes, why heavier carts hit harder, and how to build a crumple zone that saves an egg. Four lessons on inertia, speed, mass and stopping safely.
Cells: The Smallest Living Things
How small is a cell, how does water get in, what's inside, and why are cells so tiny? Four lessons with potatoes, strawberries and gelatin that work with a microscope or without one.
The Reason for the Seasons: Tilt, Daylight and the Solstice
Is summer when Earth is closest to the Sun? Students test the idea with real 2026 orbit distances and city temperatures from both hemispheres, walk a human orbit, graph real solstice day lengths from the Arctic to Tierra del Fuego and work out why a high Sun heats more than a low one. Nothing to buy: just the printed sheets and the room.
How Plants Make Food: Photosynthesis and Respiration
Where does a tree's mass come from, what happens to the sugar a plant makes, and how does the Sun's energy run a whole ecosystem? Three no-materials lessons with a 400-year-old willow experiment, printed atom cards and a carbon-atom role-play.
Natural Selection: How Living Things Change Over Time
A peppered moth hunting game over four generations, the Grants' real Galápagos finch data from the 1977 drought, whale fossils in rock-layer order with a forelimb bone comparison, and five case stations on selective breeding and antibiotic resistance. Every lesson runs on printed sheets alone: no materials to buy.
Genes and Traits: Heredity and Punnett Squares
Why you look like your family but not exactly, how two purple-flowered pea plants can have a white-flowered one, what Gregor Mendel really counted, and what happens when a gene changes. Four no-materials lessons with printed allele cards, Punnett squares, Mendel's own data and a real gene to decode.
Ecosystems and Biomes: Who Depends on Whom
Real wolf and moose counts from Isle Royale, a sixteen-card sort of competitors, predators, parasites and partners, six real climate graphs to match to their biomes, and a sea wall against a salt marsh. Four print-and-go lessons on populations, interactions, biomes and the services ecosystems give us.
Our Changing Planet: Resources and Human Impact
Where the copper, cobalt, lithium, oil and sand in a phone come from and why, which energy sources refill and which do not, what real population and energy data say about people and resources, and how real towns cut their waste. Four no-materials lessons built on printed data cards, with a hopeful, evidence-first tone for Earth Day or any time.
The Solar System: Gravity, Orbits and Scale
Pace out the whole solar system across the schoolyard from real NASA distances, walk a human orbit held together by an arm of 'gravity', graph real planet years to find the pattern, and plan a mission from planet data cards. Nothing to buy: just the printed sheets and some space.
