Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. Here's a taste from this kit; the app has the full deck.
Nature is too complicated to study all at once. So what does science do?
A model is a simplified stand-in for a real system, built to answer one particular question. It keeps the few things that decide the answer and deliberately leaves out the rest.
↳ A model keeps only what one question depends on, and lets the rest of the real system go.
The step almost everyone skips.
You cannot decide what belongs in a model until you know what the model is for. Without a stated question there is no way to separate an important detail from a decorative one.
↳ No question, no model — the question decides everything that follows.
A batter hits a six. What actually decides where it lands?
The question is whether the ball clears the boundary without touching the ground first.
↳ Change anything in the left column and the ball lands elsewhere; change the right column and nothing moves.
Why is science so fussy about words?
Everyday words such as force, work, cell and reaction carry narrow, specific meanings in science.
↳ Precision in language is what lets science be a shared activity.
Everyday word or scientific word?
↳ Carrying the everyday meaning into a science answer describes the wrong thing entirely.
Four symbols worth knowing cold.
My Very Fine Instrument runs in the same order.
↳ m, v, F, I - and each one drags a defined unit along with it.
The natural world is far too complicated to study in every detail, so science works with models — simplified stand-ins that keep only what matters for one particular question and deliberately leave the rest out, then add…

Science fixes narrow meanings for familiar words, writes quantities as agreed symbols carrying defined units, measures against international standards rather than local objects, and treats an equation as a compact statem…

Science organises what it finds into laws, theories and principles, uses them to predict what has not yet been seen, treats every idea as open to correction by evidence, and leans on rough estimation to judge whether an…

36 questions laddered from warm-up to topper-level, each with an explanation. A taste:
What is a model in science, and why does science need models?
Beginner—
Explain why leaving a detail out of a model is not the same as making a mistake.
Beginner—
A ball is hit high towards the boundary and you want to know whether it clears the rope without bouncing. State two details you would keep and two you would drop.
Intermediate—
Why is air resistance often neglected when the motion of a falling object is first studied?
Intermediate—
