Welcome to Gyanu By Rishi Sir! In today's lesson, we explore the fascinating world of Microorganisms. Did you know there is an entire invisible world living all around you—on your hands, in your food, and even inside your body? In this video for Class 8 Science (CBSE), we break down Chapter 2 to see how these tiny microbes can be our best friends and our worst enemies. 📌 What You Will Learn in This Video: We use AI-powered visuals and simple explanations to cover the entire chapter: The Invisible World: Meet the 5 main groups of microbes: Bacteria, Fungi, Protozoa, Algae, and Viruses. Helpful Friends: How Lactobacillus makes your curd and Yeast makes your bread and cakes soft and fluffy. Medical Superheroes: The story of Antibiotics and how Vaccines (like the ones discovered by Edward Jenner) act as "net practice" for your body’s immune system. Harmful Foes: Understanding Pathogens and how common "carriers" like houseflies and mosquitoes spread diseases like Malaria and Dengue. Food Safety: Why food poisoning happens and how to prevent it using salt, sugar, oil, or Pasteurization.
