Microscope Magic: Unveiling the World of Protists and Magnification

The video introduces the concept of protists and the use of microscopes to observe them. It explains key terms like magnification and resolution, and describes different types of microscopes, including light and electron microscopes. The video provides a detailed guide on using a brightfield light microscope, including handling, slide preparation, and focusing techniques. It concludes with tips for maintaining microscopes and exploring various specimens.
