Exploring the Parts of a Microscope

Mr. Pierce, a life science teacher, introduces a video series on using microscopes. The video covers the parts of a microscope, including the eyepiece, body tube, revolving nosepiece, objective lenses, arm, stage, stage clips, focus knobs, base, and diaphragm. Students are encouraged to fill out a diagram as they learn about each part. The video is part of an EdPuzzle series with questions to answer. Mr. Pierce emphasizes the importance of not disassembling the microscope and provides a comparison with another microscope diagram. The video concludes with a reminder to complete the diagram.
