    Study the different parts of a macro fungus mushroom using a magnifying glass and microscope/foldscope. Take the help of students from senior classes and explore the internal structure of different parts of mushrooms under the microscope/foldscope in your school laboratory.

    To study mushroom parts, collect a mature mushroom and observe its external parts—cap, stalk and gills—using a magnifying glass. With a foldscope or microscope, examine spores and cell structures on the gills. Seniors or teachers can guide you. This study helps understand fungi’s reproductive partsRead more

    To study mushroom parts, collect a mature mushroom and observe its external parts—cap, stalk and gills—using a magnifying glass. With a foldscope or microscope, examine spores and cell structures on the gills. Seniors or teachers can guide you. This study helps understand fungi’s reproductive parts and structure, enhancing knowledge of non-green organisms that play important ecological roles in decomposition.

    After interacting with a mushroom-growing entrepreneur, I learnt the following steps for cultivating mushrooms:

    Steps for Mushroom Cultivation:

    1. Selection of Mushroom Type
      • Common types include Oyster, Button, and Milky mushrooms. Each requires different conditions.
    2. Preparation of Substrate
      • Substrate is the material used for growing mushrooms, such as paddy straw, sawdust, or compost.
      • The substrate is cut into pieces and soaked in water for several hours.
    3. Pasteurisation
      • The wet substrate is steamed or heated to kill unwanted microbes. This prevents contamination.
    4. Spawning
      • Mushroom spawn (seed) is mixed with the cooled substrate evenly.
    5. Bag Filling and Incubation
      • The substrate with spawn is filled into poly bags or trays, with small holes for air.
      • Bags are kept in a dark, warm, and humid room (around 25–28°C) for 15–20 days until white fungal threads (mycelium) spread.
    6. Fruiting Stage
      • After incubation, bags are opened and moved to a cooler, lighted space with good air circulation and high humidity.
      • Mushrooms start forming within 1–2 weeks.
    7. Harvesting
      • Mushrooms are ready to be harvested when the cap opens fully. They are carefully twisted and plucked by hand.
    8. Packaging and Selling
      • Fresh mushrooms are cleaned, packed in plastic trays or pouches, and sold in the market. Some are dried for storage.

     

    🌱 Key Requirements:

    • Clean environment
    • Proper humidity and ventilation
    • Temperature control
    • Fresh, sterilised substrate
    • Hygiene to prevent contamination

    Some microorganisms like mold colonies on bread and mildew are visible to the naked eye as tiny spots. Among living beings, tiny insects like ants, lice or fruit flies are often the smallest visible organisms. Observing these small life forms helps develop curiosity about the microscopic world that exists beyond what our eyes can easily see.

  5. Asked: In:

    You might have seen some people using reading glasses. How does it help them see better?

    Piyush365

    With age, the eye’s lens loses flexibility, making it hard to focus on nearby objects. Reading glasses have convex lenses that help converge light rays properly onto the retina. This correction enables people to see close objects like books or mobile screens more clearly. Glasses are a simple opticaRead more

    With age, the eye’s lens loses flexibility, making it hard to focus on nearby objects. Reading glasses have convex lenses that help converge light rays properly onto the retina. This correction enables people to see close objects like books or mobile screens more clearly. Glasses are a simple optical solution based on how light bends through lenses.

  6. Asked: In:

    What happens when we use a magnifying glass to observe something?

    Piyush365

    A magnifying glass has a convex lens that bends light rays to focus them, creating a larger image of a small object. This magnification makes tiny details—like an insect’s legs or threads on cloth—easier to observe. It’s a basic scientific tool that introduces users to the concept of optics and theRead more
