Microscope slide

toothpick was used to obtain a sample of the yogurt, which was then smeared onto a clean slide. A cover slip was used to cover the slide, which was then observed for bacteria under the microscope with the resolutions 10x, 40x, and 100x with the use of immersion oil. Observations were noted and we replaced that yogurt slide with the prepared, stained yogurt slide. We compared and noted the observations between the two yogurt samples. Exercise 3: Preparing and Observing a Blood…

During the microscope lab, my partner and I learned how to properly use a microscope, calculate the field of view, and view and prepare slides. Microscopes are instruments used to view very small objects that cannot be seen with the naked eye. We found that microscopes have many different parts to them, including the diaphragm, ocular lens, and objective lenses. There are three powers of magnification, scanning power (4x), low power (10x), and high power (40x). To find the total magnification,…

Introduction The microscope is an optical instrument that produces large images of small objects that cannot be observed by the human naked eye. There are two types of light microscopes: compound microscope and Electron microscope. Light microscopes are divided into two categories: Compound microscopes and Stereoscope microscopes. Electron microscope functions in the following way; a stream of electrons emitted from an electron source built in the microscope, the obtained image is in black and…

Lab Five: Microscope and Simple Staining Introduction A microscope is a tool to examine enlarges image of small objects that are hard to study with the naked eyes. The light microscope, which was used in this lab experiment, is an instrument with two lenses and various knobs to focus the image. We will learn about the proper way to use and handle the microscope. Microorganisms are measured with an ocular micrometer, which is inserted into one of the microscope eyepiece. Micrometer serves as a…

The slide used during the Microscope Lab was a wet-mount slide which was used in order to view the specimens from the microscope. A wet-mount is a method for preparing specimens to view using a microscope. A myriad of specimens look better when placed in a drop of water on the microscope slide. The water supports the sample and fills the space between the coverslip and the slide. This allows light to pass easily through the slide, the sample, and the coverslip. Scientists use the wet-mount…

Abstract- The main material and focus in this lab is the compound light microscope. During this lab you will check the microscopes by drawing what you see to make sure the high and low powers work properly. After you tested your microscope you take a toothpick and scrap it on the side of you mouth and examine what you see through the microscope, your final results should be a drawing of what you saw through both the high and low powered lens. Introduction- This lab is based on the…

A light microscope works like a telescope using glass lenses to reflect light, which magnifies images which are naked to the human eye such as cells and dust. The lens closest to your eye is called the eyepiece lens. This usually has a magnification of x10. Objective lenses are lenses of several different strengths which magnify the image. The stage is the place where the microscopic slide sits. This is held in place by the clips. The light source (can be a mirror or a bulb) projects light onto…

Observation of plant and animal cells through a light microscope. A cell is the most basic structure of any living organism and is capable of independently reproducing. Cells can be grouped into two categories, prokaryotic and eukaryotic. In a eukaryotic cell there are small organelles that carry out specific functions which can be compared to the organs in the human body. Some of these organelles include the nucleus, which holds the cells DNA, mitochondria, which produce ATP from glucose and…

In exercise 1, experiment A, the students will need a microscope slide, a coverslip, a compound microscope, carmine powder, distilled water, and a pipette. The students will begin by placing a drop of water on the microscope slide. Then they will add carmine powder onto the slide. Then they will place a coverslip on top of the solution. This will aid in mixing the solution. Then the students will observe the movement of the carmine particles on low power and high power. In exercise 1,…

Discussion Microscope is an optical instrument that have magnifying lens which is used for inspecting objects that is too small to be seen or to be seen distinctly and in details by the unaided eye. Microscope also is an optical instrument that keep observe specimen in resolution and magnitude way. However, there are some microbes such as viruses that cannot be observe by certain microscope and this microbes has to be observe using electronic microscope which has more magnification power. In…
