Visit a laboratory for senior secondary students in your school or in a neighbouring school. Learn about the functioning of a microscope in the laboratory. Also observe how a slide is observed under the microscope.
Process of observing a slide under microscope:
- Place the microscopic slide on the stage and fix it with the stage clips.
- Look at the objective lens and stage. Turn focus knob to move stage upward.
- Observe through the eyepiece and move the focus knob till the image comes into focus.
- Arrange the mirror and condenser to focus and reflect the maximum amount of light to the slide.
- With the use of a focus knob, obtain a clear view of the sample and readjust the condenser with a low power objective for the clearest image.
- Change the objective lens to high power after a clear image of the sample is obtained with the low power objective.
- Again, with the use of focus knowledge, obtain a clear view of the sample with high power objective lens.
- Do not let the objective lens touch the slide.
