Introduction to the Microscope PRE-LAB QUESTIONS Label the following microscope using the components described within the Introduction.  1. binocular eye piece 2. arm 3. base 4. clamps 5. Light source 6. stage 7. objectives 8. Condensor diaphragm dial 9. head © eScience Labs, 2018 Introduction to the Microscope EXERCISE 1: VIRTUAL MICROSCOPE Post-Lab Questions 1. What is the first step normally taken when you look through the ocular lenses? - adjust the width of the eyepiece until you see one circle of light in the field of view. 2. What does it mean that the image is inverted when you look through the ocular lenses? - if you physically move the slide away from you, the specimen will appear to move towards you 3. What is the difference between the coarse adjustment knob and the fine adjustment knob? When is it appropriate to use them? - the coarse adjustment is enough for focusing at 4x or 10x magnification, but you can use the fine focus to sharpen the image. - use the coarse focus adjustment to get the sample into focus. you can use the fine focus to sharpen the image. 4. What new details are you able to see on the slide when the magnification is increased to 10x that you could not see at 4x? What about 40x? © eScience Labs, 2018 Introduction to the Microscope - 10x – You see more then just the shape and color you can see what the specimen looks like or is made up of at 40x you are focusing on the smaller components of the specimens makeup © eScience Labs, 2018
