The Science Edit

Science is getting seriously spooky!

This Halloween, we’re exploring the darker, stranger and downright gruesome side of science.

From creepy parasites and zombie rats to the bizarre world of different coloured blood, discover some of nature’s most horrifying secrets.

Can parasites really control their hosts? What turns a rat into a zombie? And why isn’t all blood red?

Prepare for fascinating facts, gruesome discoveries and science that’s stranger than fiction!

Enzymes are one of the core topics in both GCSE Combined Science and Triple Biology, forming the foundation for understanding digestion, metabolism and many of the chemical reactions that keep living organisms alive.

In this episode of The Science Edit A–Z of Biology, we break down everything you need to know about enzymes, from the lock and key theory and active sites to the effect of temperature, pH and substrate concentration on enzyme activity.

With clear explanations, common exam pitfalls and links across the GCSE specification, this episode is perfect for anyone looking to strengthen their understanding and maximise their marks in the exam.

DNA is one of the most important topics in GCSE Biology, linking together genetics, inheritance, protein synthesis and evolution.

In this episode of The Science Edit A–Z of Biology, we explore D is for DNA, explaining its structure, how genetic information is stored and why DNA is often described as the blueprint for life.

We’ll also look at genes, chromosomes and genomes, making sense of the key ideas that frequently appear in GCSE exam questions.

Whether you’re revising for your mocks or aiming for those Grade 9 answers, this episode will help you build confidence and strengthen your understanding of one of biology’s most fascinating topics.

Cells are the building blocks of all living organisms, and understanding them is essential for success in Biology.

In this episode of The Science Edit A–Z of Biology, we explore C is for Cells, covering everything from specialised cells and cell structures to microscopy, diffusion and the differences between animal, plant and bacterial cells.

Whether you’re aiming to secure a strong pass or pushing for those elusive Grade 9 answers, this episode is packed with clear explanations, exam tips and the key knowledge you need to feel confident in your Biology exams.

Grab your revision guide, get comfortable and let’s dive into the fascinating world of cells!

Welcome back to The Science Edit A–Z of Biology!

In this episode, we’re exploring blood. Blood is far more than just a red liquid flowing through your veins. It’s a remarkable tissue that transports oxygen, nutrients and hormones, removes waste products and plays a vital role in protecting your body from disease.

We’ll take a closer look at the four main components of blood, discover how each one keeps you alive and healthy, and explain why understanding blood is so important for GCSE and A Level Biology.

Whether you’re revising for an exam or simply curious about how your body works, this episode has something for you.

Need a quick science boost? This episode is perfect for Year 7 and 8 revision.

We break down the basics of solids, liquids and gases, changes of state like melting and evaporation, and how diffusion works. Clear explanations. Key words you need to know. The ideas that show up again and again in tests.

If you want to feel more confident in science, start here.

Revising for GCSE Biology and aiming for a Grade 9?

The A–Z of Biology series is designed to help you connect the big ideas across the course, not just memorise them. Each episode focuses on one key topic and shows how it links to other areas of the specification…the kind of synoptic thinking examiners reward at the highest grades.

In this episode we use antibiotics to connect ideas about bacterial structure, binary fission, drug testing, the antibiotics core practical, and the evolution of antibiotic resistance. Expect clear explanations, key exam terminology, and the links across the course that help push your answers into the top mark bands.

Thinking about taking Science at A level but not sure if it’s the right choice? In this episode, Sixth Form students talk honestly about what studying Biology, Chemistry and Physics at A level is really like. They discuss workload, content depth, how different it feels from GCSE, and what surprised them most once they started. If you’re weighing up your options or wondering whether science is for you, this episode will help you make an informed decision.

In this episode, I’m joined by Sixth Form students to explore the Biology topics GCSE students most often get wrong – and how to get them right.

From enzymes and osmosis to inheritance and graph analysis, they break down tricky concepts and share how they tackled them during their own revision.

There’s also discussion on how to approach six-mark questions and what really helps when it comes to learning Biology more confidently.

In this episode of The Science Edit we dive into the wonderfully revolting world of gross science. Listeners submitted their most disgusting science facts and our sixth form researchers have investigated which ones are actually true.

From worms that travel across your eyes to lizards that defend themselves by firing blood, from frogs cleaning out their own stomachs to the surprising truth about how much snot you produce each day, this episode uncovers the science hiding behind the facts you wish you could un-hear.

If you enjoy strange biology, unbelievable adaptations, and learning why your phone is one of the dirtiest things you own, this is the perfect episode to start with. Science is not always glamorous, but it is always fascinating.
