About GCSE Science Simplified (All GCSE Science in one place)
GCSE Science Simplified is your go-to podcast for mastering key content in GCSE Biology, Chemistry, and Physics. Perfect for Combined and Triple Science students, each episode breaks down topics into clear, manageable chunks with tips to help you remember and apply what you’ve learned. Whether you're revising at home or on the move, this is the revision companion to help you pass your GCSEs with confidence.
How do you turn a black powder into bright blue crystals — and prove they’re pure?
In this episode of GCSE Science Simplified, we break down GCSE Chemistry Core Practical 3, preparing pure, dry hydrated copper sulfate crystals from copper oxide and sulfuric acid.
You’ll learn:
How neutralisation reactions work: acid + base → salt + water
Why metal oxides act as bases in these reactions
Why adding excess copper oxide ensures no acid remains
How filtration separates residue and filtrate
Why a water bath is used for controlled evaporation
How crystals form during cooling and crystallisation
We also cover key practical skills and exam focus points:
Identifying residue vs filtrate
Avoiding common mistakes in evaporation
Understanding why not all water should be removed
Writing clear, GCSE-level explanations of the method
Perfect for:
GCSE Chemistry revision (Edexcel, AQA, OCR)
Mastering required practical experiments
Improving exam technique and extended answers
Clear explanations. Strong exam links. Practical understanding.
Listen now to master copper sulfate preparation, neutralisation, filtration, and crystallisation — and boost your GCSE Chemistry confidence.
How do you turn an acid into something neutral — and how do you prove it?
In this episode of GCSE Science Simplified, we break down GCSE Chemistry Core Practical 2, investigating pH changes during neutralisation using hydrochloric acid and calcium hydroxide (or calcium oxide).
You’ll learn:
What pH actually measures (hydrogen ions vs hydroxide ions)
How neutralisation works: H⁺ + OH⁻ → H₂OHow to track pH changes using universal indicator and pH probes
What happens when a solution moves from acidic → neutral → alkaline
How to identify the exact point of neutralisation (pH 7)
Common practical errors — and how to improve your method
This episode is perfect for:
GCSE Chemistry revision (Edexcel, AQA, OCR)
Understanding acids, alkalis, and pH scale
Preparing for required practical exam questions
Clear explanations. Real experimental thinking. GCSE-ready understanding.
Listen now to master pH, neutralisation, and core practical skills — and boost your exam confidence.
Is your pen lying to you?
In this episode of GCSE Science Simplified, we break down GCSE Chemistry Core Practical 1 — investigating the composition of inks using paper chromatography and simple distillation.
You’ll learn how scientists separate mixtures and reveal what substances are really present, using clear explanations, memorable models, and exam-ready language.
We cover:
How paper chromatography works (mobile phase vs stationary phase)
How to interpret a chromatogram
How to identify pure and impure substances
How to compare unknown substances using Rf values
Why key method steps matter (pencil lines, solvent level, solvent front)
The principles behind simple distillation and separation by boiling point
Perfect for:
GCSE Chemistry revision (Edexcel, AQA, OCR)
Understanding core practical experiments
Improving exam technique and avoiding common mistakes
This episode helps you move beyond memorising steps — and actually understand how and why separation techniques work.
Listen now to master chromatography, distillation, and core practical skills for GCSE success.
