GCSE Biology Lesson 4: Required Practical - Culturing Microorganisms (AQA, OCR, Edexcel)

Hi there, curious minds! Welcome back to my channel 👋

Today's lesson is revising how to culture microorganisms for the required practical in GCSE Biology. This will only be assessed in the triple Science exam, so if you're learning a combined course, you won't need to revise this for the exam (although stay if you're interested anyway!)

Did you know, we have around 1 million bacteria on every square centimetre of our skin! It's amazing as they help prevent harmful bacteria from infecting us. 🦠
