What are mircoscopes?

Some mircoscopes scientists may use are;The compound mircoscope,a compound microscope is also called light miscroscope because it uses two lenses to magnify objects. Compound microscopes have low depth low depth perception but have high resolution and magnification.They may also use stereo mircoscope,a stereoscopic microscope or stereo microscope has two eyepieces, so you get to use both of your eyes at a time. This helps to make the object you are looking at more three-dimensional.

Scientist use mircoscopes for many different purposes. Whether it be in forensics or traditional medical science, the microscope is an indispensable instrument.

Scientists use mircoscopes when looking at cells because cells can be very,very smalls and you can not see them through the naked eye.Therefore they use mircoscopes to look closer at the cells.

What is the difference between a wet and a dry mount slide?

- a wet mount is freshly prepared while a dry mount is pre-prepared and sealed.
- the specimen is alive in a wet mount while in a dry mount the specimen is dead .
- air bubbles can be trapped in a wet mount but not in a dry mount .
- wet mounts are priceless while dry mounts costs.

First place 1-2 drops of water on the slide. Then put whatever you're going to view under the microscope on top of the water droplets. Then you place the cover on top of it. The water seals the cover and the slide together, keeping the organism in the middle without letting it fall out.
