What is the function of the eyepiece in a microscope?

• The eyepiece adjusts the stage height.

• The eyepiece focuses light onto the specimen.

• The eyepiece illuminates the sample.

Name the part of the microscope that holds the slides in place.

• eyepiece

• base

• objective lens

• stage

How do you adjust the focus on a microscope?

• Change the objective lens to focus

• Use the coarse focus knob for initial focus and the fine focus knob for precise adjustments.

What is the purpose of the stage on a microscope?

• To adjust the focus of the microscope.

• To illuminate the slide with light.

• To hold and support the slide containing the specimen.

Describe how to prepare a wet mount slide.

• Place a drop of specimen on a coverslip, then lower the slide over it.

• Add a drop of water to the slide, then place the specimen on top without a coverslip.

• Use a microscope to directly view the specimen without preparing a slide.

• Place a drop of specimen on a slide, lower a coverslip over it.

What is the role of the objective lens in a microscope?

• The objective lens illuminates the specimen from below.

• The objective lens focuses light from the specimen to create a magnified image.

• The objective lens adjusts the focus of the eyepiece.

How should you clean the lenses of a microscope?

• Blow on the lenses to remove dust and dirt.

• Use water and paper towels to scrub the lenses.

• Use a soft cloth or lens paper with cleaning solution to gently wipe the lenses.

• Wipe the lenses with your shirt or any fabric.

Why is it important to start with the lowest power objective?

• To ensure the slide is clean before viewing.

• To increase the magnification quickly.

• To avoid using the coarse focus knob.

What materials are commonly used for making microscope slides?

• Wood and metal
