    Anton van Leeuwenhoek, a Dutch scientist, is called the Father of Microbiology. He crafted powerful single-lens microscopes and became the first person to observe live bacteria, protozoa and other microorganisms. His discoveries amazed scientists and proved that an unseen world of living creatures existed all around us, changing the course of science and medicine forever.

    The aim of Activity 2.1 is to help students understand how magnification works. When water is filled in a round-bottom glass flask and placed on a book, the curved surface bends light rays. This makes the letters underneath appear bigger. It mimics how lenses in magnifying glasses work, helping us explore the basics of magnification used in microscopes.

  4. Inside a round-bottom flask, water takes on a convex shape, meaning it bulges outward. When light passes through this curved water surface, it bends or refracts, focusing the rays and enlarging the view of the object beneath. This natural refraction mimics how magnifying lenses work, allowing tiny dRead more

    Inside a round-bottom flask, water takes on a convex shape, meaning it bulges outward. When light passes through this curved water surface, it bends or refracts, focusing the rays and enlarging the view of the object beneath. This natural refraction mimics how magnifying lenses work, allowing tiny details of an object to become more visible and clearer.

    The activity using a flask filled with water and a book helps students understand how magnification works. By placing the flask over printed text, the letters appear enlarged due to the bending of light rays through the curved glass and water. It illustrates how simple lenses or water-filled surfaces can make small objects look bigger, just like microscopes do.
