The compound light microscope, which is going to be used in this lab activity, is an instrument with two lenses and various knobs to focus the image. In this lab, we will learn about the microscope and how to properly use it (Kim, 2001). Anton van Leeuwenhoek (2001) was the first person to observe and describe single celled organisms by using handcrafted microscopes. He originally referred to these single celled organisms as animalcules which we now call microorganisms. Even though he was the first person to do all of this, however he was also the first to record and observe muscle fibres, spermatozoa, bacteria and blood flow in capillaries which are also referred to as small blood vessels. Zacharias Jansen (2001) is known to be the first creator of the compound microscope and is dated around the 1590's. There were …show more content…

To do this lab, a compound light microscope is needed to examine the letter “e” which will need to be cut out from a newspaper. In order to cut out the e from the newspaper, a pair of scissors will be needed. Once the e is cut out place the letter “e” onto the glass slide. Drop one drip of water onto the glass slide and drop the “e” right-side up onto the drop of water. When finished place the cover slip onto the drop of water. Make sure that there is no bubble so drop the cover slide slightly onto the water drop. Then place the slide onto the compound light microscope and then place the focus onto 10X. Then adjust the focus onto the “e” until the e is clearly
