In this lesson on microscope usage, students reviewed the main components of a microscope, including the nosepiece, objective lenses, stage, and focus knobs, and discussed their functions and importance in obtaining clear images. Particular attention was given to safety practices, such as wearing goggles, handling slides by the edges to avoid fingerprints, and disposing of broken glass properly. Emphasis was placed on avoiding contact between the high power objective lens and the slide to prevent damage, and ensuring that microscopes are stored with the low power objective lens to avert accidents.
