How to use a Microscope?
1. An investigation with the microscope always starts by using the lowest power objective lens, then working up to the highest power objective lens if it is required.
2. A specimen for viewing under the microscope must be put on a glass slide. The slide is put on the stage and held in place by the stage clips. The slide should be positioned so that the specimen is in the centre of the hole in the stage.
3. Watch from the side of the microscope as you turn the knob to bring the objective lens and specimen close together. When the objective lens and the specimen are close together, but not touching, look down the eyepiece and turn the focusing knob so that the objective lens and specimen move apart. If you do this slowly, the blurred image will become clearer.
