Mastering Microscope Techniques in Biology

This video tutorial provides a comprehensive guide on using microscopes in a Biology 10 lab. It covers setting up the microscope, using it effectively, troubleshooting common issues, and proper cleanup and storage. The video emphasizes safety, proper handling, and maintenance to ensure optimal use of the microscope.

What is the correct way to carry a microscope?

• With both hands on the base

• With one hand on the arm and the other under the base

• With both hands on the stage

• With one hand on the ocular lens

Where is the on/off switch located on the microscope?

• On the front of the microscope

• On the side of the microscope

• On the back of the microscope

• Under the stage

What should you do if the power cord is still wrapped around the holders?

• Use a different microscope

• Cut the cord

• Leave it as it is

• Unwind the cord and plug it in

How should the light be adjusted for optimal viewing?

• Always set to the brightest level

• Set to medium or medium high

• Always set to the lowest level

• Set to the highest level

What is the first step when using the microscope to view a specimen?

• Start with the medium power lens

• Start with the stage at its lowest position

• Start with the low power objective lens

• Start with the highest power lens

What should you do if the slide doesn't move when adjusting the slide holder?

• Use more force

• Check if the slide is clipped properly

• Ignore it and continue

• Replace the slide

What is a recommended method for focusing on unstained specimens?

• Use the brightest light setting

• Find a bubble or easily observed object

• Use the highest power lens

• Ignore the diaphragm setting

What should you use to clean a blurry lens?

• A regular tissue

• A cotton swab

• A piece of cloth

• Lens paper with lens cleaner

What is the first step in cleaning up after using the microscope?

• Move the stage to a centered position

• Wrap the cord

• Remove the slide

• Turn off the light and power

How should the microscope be stored after use?

• With the power cord plugged in

• With the stage at its highest position

• With the arm facing in

• With the arm facing out
