Transcript of "Microscope Lab"

  1. 1. The Microscope
  2. 3. Parts of a Microscope
  3. 4. What is the Microscope? <ul><li>A device for looking at things too tiny to see with the naked eyes. </li></ul><ul><li>Anton Van Leeuwenhoek, a Dutch scientist invented the first microscope in 1660 </li></ul>
  4. 5. Parts of the microscope <ul><li>Arm: The arm supports the body tube. </li></ul><ul><li>Stage: support slide being viewed. </li></ul><ul><li>Stage clip: hold slide in place. </li></ul><ul><li>Body tube: maintains the proper distance between the eye piece and the objectives. </li></ul>
  5. 6. Parts of the Microscope <ul><li>Coarse adjustment : moves the stage up and down to focus the imagine. </li></ul><ul><li>Fine adjustment: moves the stage slightly to sharpen the image. </li></ul>
  6. 7. Parts of the Microscope <ul><li>Eyepiece: Contains a magnifying lens 10X. </li></ul><ul><li>To magnify: means to make something bigger </li></ul><ul><li>Objective lens: magnify the objective lens and </li></ul><ul><li>can be rotated to change the magnification. </li></ul><ul><li>scanning =4x Lower power =10x </li></ul><ul><li>higher power =40X </li></ul><ul><li>To determine the total magnification, multiply the magnifying power of the eyepiece by the magnifying power of the objective lens. </li></ul><ul><li>Example: 10 X 4=40 10 X 10= 100 10 X 40=? </li></ul>
  7. 8. Parts of the Microscope <ul><li>Illuminator: light source </li></ul><ul><li>Diaphragm: produces light or reflects light up toward the eyepiece. </li></ul>
  8. 9. How to hold/carry a microscope                                               
  9. 10. <ul><li>Objective </li></ul><ul><li>The objective of this lab is to learn the use of a compound light microscope and observe the effects of changing the magnification and position of the sample on the view of the sample. </li></ul>Introduction to the Compound Light Microscope
  10. 11. Procedure <ul><li>Cut out a small letter “e”from the newspaper. </li></ul><ul><li>2. Once we had cut that out we put in on the slide and add a drop of water to it. </li></ul><ul><li>3. Afterwards we cover it with a cover slip and put it on </li></ul><ul><li>the microscope. </li></ul><ul><li>4. Adjusting it to the blue lens which magnified 4x, </li></ul><ul><li>5. Our next step was to magnify the same letter 10x. </li></ul>
  11. 12. Illustration <ul><li>Sketch what you see with a pencil with 4x </li></ul><ul><li>Sketch what you observe with the 10x </li></ul>
  12. 13. Result <ul><li>We found that the letter e was turned upside-down </li></ul>
