The theme I will be following is identity. We all come from somewhere; we all have backgrounds and pasts; we all have an identity that’s more than just a name. September 30th of 1999, I entered this world. I was given the name Sherri, and I was full of potential. My personality could be shaped by anything, bits and pieces of who I am today were things I picked up in my past. I could tell you my life story, but I couldn’t exactly pick out how I came to be this way. To tell you about parts of my identity, I can tell you about how I discovered some of my taste in music and about how very eventful my teenager life is.
Part of my identity is made up of music. I have a very expansive taste in music. If you were to hit shuffle on my playlist you’d…
Magnification Loupes in U.S. Entry–level Dental Hygiene Programs – Occupational Health and Safety written by Dongdon, Tolle, Darby (2012)
The purpose of this study was due to improving dental hygienists environmental stressors and improve occupational health of dental hygienists by the American Dental Hygienists’ association’s (ADHA). The National Dental Hygiene Research Agenda states that occupational health and safety introduced the magnification of loupes so that it could reduce stressors…
Under 100x magnification – a view of purple rod shaped bacteria/bacilli; some appear as either single rods or paired rods (diplobacillus).
Yoghurt prepared – under 40x magnification

Under 40x magnification – a view of loads of bacteria moving about with undefined shapes.
Under 100x magnification – an indistinct view of loads of varied bacteria moving about, such as diplococci, streptococci, staphylococci,…
rhizopus stolonifer (bread mold, a fungus), and Bacterial cells (bacilli). Each cell was observed under high power lens (except for rhizopus stolonifer) with a total magnification of 400μm and a dFOV of 400μm. The estimated object size, scale bar, and drawing magnification of each cell was found except for cardiac muscle. Each cell appeared much larger under the microscope allowing each cell to be viewed and observed closely. The cardiac muscle cell consisted of striations and many nuclei.…
VS2 (Very Slightly Included 2), Inclusions/Blemishes are difficult to spot under 10X magnification by a trained professional.
SI1 (Slightly Included 1), Inclusions/Blemishes are seen under 10X magnification by a trained professional.
SI2 (Slightly Included 2), Inclusions/Blemishes are seen under 10X magnification by a trained professional.
I1 (Included 1), Inclusions/Blemishes are obvious under 10X magnification

It can be measured in degree as angular field of view or in feet as the width of the area viewed at 1,000 yards. As the field of view increase, the image clarity get poorer. Also, a higher magnification means a narrower field of view.
• Eye Relief
Eye relief is measured in millimeters as the distance indicating how far the scope can be held from the eye while still seeing the entire field of view. People wearing glasses would love a longer eye relief
• Exit Pupil
If you love brighter images…
Determining total magnification; first I start with the low-power objective, then the high-power objective, from 4x to 40x and I start take notes on the white sheet of paper and drawing what did determining on the low-power objective and high-power. Also,I repeat steps two to four for the color threads slid.
4. After I finished my observation I removed the slide and clean it up, turn off the microscope and wind up the wire so it resembles its original position. Place the low-power objective in…
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.
This lab is based on the compound light microscope. “A compound light microscope is a microscope that allows light to pass through a specimen and uses two lenses to form a image”. The compound light microscope has two main lenses. The two main lenses are the low…
point behind the lens and the focal length be negative. The incoming rays are the rays the light source sends through the lens and the transmitted rays are the ones that were passed through the lens.
The next two parts on finding the focal lengths and magnifications required tables. For the first part on converging lenses the first thing found was the focal length, as described in the procedure, which was 188mm. The object height, diameter of the light source, was 40mm. After finding these and…
The relation between the magnification and the working is inversely proportional; when the magnification is bigger the working distance becomes smaller.
Experiment 2: field of view of the high-power objective
Use a transparent ruler that serves as a specimen.
Turn on the illuminator of the microscope, use the nosepiece to put the scanning objective (4X) magnification.
Place the ruler on the stage. Move the stage clips so that…
