Recently we have been learning about microscopes and how to use them. I learned that our classroom has two kinds of microscopes.. The compound microscopes which have a more powerful zoom, and the digital microscopes that project the image onto the computer.Theres also this thing called the focal plane, which is the plane that is in focus. By adjusting the nob, you can bring the thing closer of farther away to change the plane that you are focusing on. Microscopes help us study objects and organisms that are unable to view from the human eye.
