3. why is it important to keep a microscope covered when you’re not using it? (seek answer from the course and put in your own words. use complete sentences).

It is important too keep a microscope covered when you are not using it can greaty prevent containation and also because it can prevent dust from gathering on the lens of the microscope. Another conclusion I have made as of why you should cover a microscope when you are not using it is that, if the microscope is close to light and it is turned at a certain angle, it can start a fire if the force of power, and the angle is great enough.
