Label the Compound Light Microscope (Handout) Ocular lens Body Tube Coarse Adjustment Knob Fine adjustment Knob Revolving nosepiece Objective lenses (4x, 10x, 40x) Arm Stage Stage Clips Diaphram Light source Base

Focusing with a Microscope Plug in and turn on. Lower stage completely. Turn nosepiece to low objective. Raise stage with coarse objective until specimen is seen. (Big knob) Fine focus the specimen. Centre specimen in the field of view. Rotate nosepiece to medium power objective. Refocus with fine adjustment. Re-centre the specimen. Refocus with fine adjustment. (Be careful not to break the slide.) Adjust the condenser. (Light) Start over to look at another specimen. Carrying and storage instructions. Demo with camera.
