Incandio Science

Three Pearson Edexcel International GCSE courses, 194 lessons, 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
• Topic 4 · Energy resources and energy transfers — 7 lessons
• Topic 5 · Solids, liquids and gases — 7 lessons
• Topic 6 · Magnetism and electromagnetism — 6 lessons
• Topic 7 · Radioactivity and particles — 9 lessons
• Topic 8 · Astrophysics — 7 lessons
