Scientist use it to discover and investigate small objects and structures.]]> 2022-10-07 12:51:59 UTC https://padlet.com/seowonchoi1/vpdkgmnu37w86u9r/wish/2330943950 seowonchoi1 https://padlet.com/seowonchoi1/vpdkgmnu37w86u9r/wish/2330948902 Light microscope is the microscope that many people are familiar with. It allows light to pass through a specimen and uses two lenses to form an image. Objective lens and ocular lens. It can produce a magnification of 1000 times.]]> 2022-10-07 12:55:35 UTC https://padlet.com/seowonchoi1/vpdkgmnu37w86u9r/wish/2330948902 seowonchoi1 https://padlet.com/seowonchoi1/vpdkgmnu37w86u9r/wish/2330953626 Light microscopes are used to look at cells and cell structure that are as small ass 1millionth of a meter. They use beams of electrons focused by the magnetic field. Because of this, electron microscopes can offer much higher resolution than light microscopes. ]]> 2022-10-07 12:59:09 UTC https://padlet.com/seowonchoi1/vpdkgmnu37w86u9r/wish/2330953626 seowonchoi1 https://padlet.com/seowonchoi1/vpdkgmnu37w86u9r/wish/2330957135 Transmission electron microscopes makes it possible to explore cell structures and large protein molecules. The beams can only pass through a thin object, so the image is usually flat and two dimensional.]]> 2022-10-07 13:01:35 UTC https://padlet.com/seowonchoi1/vpdkgmnu37w86u9r/wish/2330957135 seowonchoi1 https://padlet.com/seowonchoi1/vpdkgmnu37w86u9r/wish/2330959583 Scanning electron microscopes uses a pencil-like beam of electrons to scan over the surface of a specimen. This makes it possible for it to produce a image that is three-dimensional.]]> 2022-10-07 13:03:28 UTC https://padlet.com/seowonchoi1/vpdkgmnu37w86u9r/wish/2330959583 seowonchoi1 https://padlet.com/seowonchoi1/vpdkgmnu37w86u9r/wish/2330964085 In the late 1500s, Europeans discovered that when they look at things using several glass lenses, you could magnify small objects. The first official microscope was invented by Zacharias Janssen in the 1600s. In 1665, Robert Hooke used an early microscope to look at a nonliving thin slice of cork. As time passed, people developed better microscopes using their technology and lead to the microscopes we use today.]]> 2022-10-07 13:06:58 UTC https://padlet.com/seowonchoi1/vpdkgmnu37w86u9r/wish/2330964085 seowonchoi1 https://padlet.com/seowonchoi1/vpdkgmnu37w86u9r/wish/2330967888 Microscopes allows us to look at small objects and structures that we can't see. It helps scientist discover new information and helps us understand the small world that we can't see with our naked-eye.]]> 2022-10-07 13:09:51 UTC https://padlet.com/seowonchoi1/vpdkgmnu37w86u9r/wish/2330967888
