Incandio Science
Three Pearson Edexcel International GCSE courses, 194 lessons, completely free. Every lesson names the specification statements it covers, explains them in plain language first, then gives the exact notes a Grade 9 answer needs — and five questions that climb from Grade 6 to beyond Grade 9, marked on your own device.
Then the part a textbook cannot do: you teach the idea back to Ember, an AI apprentice who asks the awkward question, and defend it against the scientist with the strongest genuine claim on it.
Biology — Pearson Edexcel International GCSE in Biology · 4BI1
Life, from a single cell to a whole ecosystem. Biology rewards students who can explain a PROCESS — how one thing causes the next — rather than recite a list, and every lesson here is built to teach it that way.
68 lessons across 5 topics:
- Topic 1 · The nature and variety of living organisms — 3 lessons
- Topic 2 · Structures and functions in living organisms — 34 lessons
- Topic 3 · Reproduction and inheritance — 15 lessons
- Topic 4 · Ecology and the environment — 8 lessons
- Topic 5 · Use of biological resources — 8 lessons
Chemistry — Pearson Edexcel International GCSE in Chemistry · 4CH1
Everything is particles, and everything chemistry asks of you follows from what those particles are doing. These lessons make the invisible layer visible first — then the equations, the conditions and the calculations stop being arbitrary.
61 lessons across 4 topics:
- Topic 1 · Principles of chemistry — 18 lessons
- Topic 2 · Inorganic chemistry — 19 lessons
- Topic 3 · Physical chemistry — 8 lessons
- Topic 4 · Organic chemistry — 16 lessons
Physics — Pearson Edexcel International GCSE in Physics · 4PH1
Physics is not a list of equations to memorise. Every equation here is introduced only after you understand the relationship it describes — what each quantity really is, why they connect that way, and what happens when one of them changes.
65 lessons across 8 topics:
- Topic 1 · Forces and motion — 10 lessons
- Topic 2 · Electricity — 9 lessons
- Topic 3 · Waves — 10 lessons
