Often times, we overlook important life skills and lessons in the lab setting. The following memo to my students help share with my students my expectations in the lab when using the microscope.

RE: Things To Remember When Using The Microscope
- to prevent dust collection, be sure to keep the dust covers on microscopes when they are not in use.
- be sure that all microscopes are set to the low power objective when lab investigation has been completed.
- clean off eyepiece and aperture after completing the lab.
- lift the microscope to relocate them. do not drag the microscope on any surface. this will damage the lens!
- always begin on low power!
- when rotating the nosepiece, turn slowly and wait for the click.
- when changing your diaphragm setting, wait for the click.
- only the fine adjustment knob should be used when on high power.
- if you look through the eyepiece and your field of view is dark, check the following:
- be sure the microscope is plugged in and lamp is on.
- be sure that the diaphragm is clicked into place and not in between settings (opening).
- be sure that the nosepiece is clicked into place and aligned with the aperture.
- be sure to use forceps carefully in order to prevent scratching the slide or coverslip.
- glass slides can be cleaned and reused.
- plastic coverslips can be discarded at the end of its use.
Enjoy Your Journey Into The Microcosmos!
** I laminate a copy for each pod as a reminder when the microscopes are part of the lab investigation. For actual copy with graphics, feel free to email me. It is a MS Word doc.
Remember - life lessons are just as valuable, if not more, than teaching our scientific concepts and standards!
