Labs & simulations
Run the experiment instead of reading about it — chemistry, physics, biology and the night sky, all interactive.
Grades 6-8 · Ages 11 to 14
Some questions are worth climbing for.
Science, math, English, history and coding — taken to real depth for curious 11-to-14-year-olds, with an account a parent sets up and manages.
Nothing dumbed-down. You're 11 to 14 — ready for real depth, real evidence, and ideas worth arguing about.
Nothing overwhelming. Every subject breaks into clear skills that adapt to what you find hard, so you always know what's next.
Nothing hidden. A parent sets up the account and can see how it's going. No ads, ever.
What do you want to learn today?
Six core subjects for grades 6-8 — pick one and go deep.
Science · Chemistry & the lab
Find out what things are actually made of
A colour change in a beaker is atoms rearranging in front of you. Koydo Learn takes chemistry, biology, physics and earth science to real depth — building each idea on evidence you can test, with adaptive practice that leans into whatever you find hardest.
- Chemistry, biology, physics and earth science for grades 6-8
- Explanations built on real evidence, not memorisation
- Adaptive practice that targets your weak spots
STEM · Engineering & design
Turn math into something that actually works
Every bridge, circuit and machine is math and science made real. Koydo Learn connects pre-algebra, ratios, geometry and data to how things are designed and built — so the math has a point, and the point is something you could make.
- Pre-algebra, ratios, geometry and data for grades 6-8
- See where each idea shows up in real engineering
- Step-by-step hints instead of red X's
History · The ancient world
History is a case you get to solve
An artefact in the dirt is a clue, and history is what you build from the evidence. Koydo Learn treats the ancient world and the modern one as something to investigate — weighing sources, spotting bias, and arguing a case — not a list of dates to memorise.
- Civilizations, evidence and the modern world
- Weigh sources and spot bias like a historian
- Ideas worth thinking — and writing — about
Science · Life & ecology
Read the living world, then explain it
A stream is an ecosystem you can measure — and then write up so someone else understands it. Koydo Learn builds the close reading, evidence and clear-writing skills that let you take in something complex and explain it in your own words, across science and English alike.
- Close reading, argument and essay structure
- Turn evidence into clear, well-built writing
- Life science and ecology grounded in real fieldwork
