Science

Science is usually taught as a very large pile of facts, and that is why so much of it evaporates. You learn that water evaporates and condenses, that plants photosynthesise, that energy is lost in a food chain — and each fact sits on its own, unconnected to the others, until it fades. What is missing is not more detail. It is the shape: what causes what, what feeds back into what, and where a process starts and stops.

That shape is what this subject is built around, because it happens to be exactly what science is made of. A great deal of the natural world is cycles and flows. Water goes round a loop that never ends. Energy travels one way through a food chain and runs out. Removing one species sends effects along every connection it had. None of that is a list of facts — it is structure, and structure is far harder to forget than a definition.

So every concept here starts as an interactive playground rather than a paragraph. You get a handful of labelled pieces on a canvas and you connect them the way they genuinely relate. If you connect the water cycle as a straight line rather than a loop, you find out immediately, and working out why it has to close is the moment the idea lands. The written explanation, a real-world example and a short quiz come afterwards, once you have something to attach them to.

You will also meet a habit that is part of science itself: being clear about how certain we are. Where a well-known story is genuinely debated — such as how much of the change at Yellowstone the returning wolves actually caused — this subject says so, rather than presenting a tidy version. Learning that evidence has strength as well as content is not an advanced topic; it is the difference between knowing some science and being able to think about it.

Biology covers the flows that keep living things going: the water cycle, photosynthesis, food chains, and what happens when a species is lost. Chemistry goes down to the particle level — why the same substance behaves as ice, water or steam, and what energy does when it moves between them. Physics tackles the two ideas most people hold slightly wrong: that energy gets used up, and that moving things need a constant push. Each of those is a discipline rather than a topic, so each will keep gaining tracks — cells and the human body are being written for Biology next, and Earth and Space Science will become its own category once there is enough of it to justify one. Nothing here assumes prior science, and there is no equipment to buy or maths to do.
