In this chapter you will be using a microscope to view different types of cells. Parts of the microscope Study the diagram below which shows the parts of a microscope.
Your microscope may be slightly different from this one. However, the basic parts will be the same. If you are in doubt, ask your teacher for advice.
Rotate the objective lenses until the low power lens clicks into position directly above the hole in the stage. (The low power objective lens is usually the shortest one, and has the lowest number stamped on it, e.g. x4.)
Place a hair on a microscope slide and put it on the stage.
Looking from the side, turn the focusing knob to move the lens very close to the slide.
Now look through the eyepiece lens and move the objective lens away from the slide until the hair is in focus.
Rotate the higher power objective lens into place. (You may need to use the fine focus knob to make the image clearer.)
A microscope magnifies things. Each lens of a microscope has its magnifying power marked on it. Look at the eyepiece lens. You may see the number x10.
This means that this lens magnifies things to 10 times their original size. The objective lenses are marked in the same way.
The total magnifying power of the microscope is found by multiplying the power of the eyepiece lens by the power of the objective lens.
If the eyepiece is x10 and the objective lens is x10, then the microscope will magnify the object 100 times.
Place a drop of water in the middle of a microscope slide.
Cut out a small lower case 'e' from a piece of newspaper and place it on the drop of water on the slide. Cover the 'e' with another drop of water.
Place the edge of the cover-slip on the edge of the drop of water, and lean it on a pencil, as shown.
Lower the pencil slowly and let the cover-slip fall flat on the slide. (This stops air bubbles forming under the cover-slip.) You should do this a few times to master the skill.
5 Place the slide on the stage and observe the letter under low power. /•A, Lj Record your observations. Is the 'e' the right way up? Move the slide to the left. Which way does the 'e' move when viewed through the lens? Questions 1 Suppose you place the number '5' under the microscope. Draw what you would expect to see through the lenses. Explain your drawing. 2 A cell is 0.01 mm long and 0.02 mm wide. How big would it be if you viewed it under a microscope with a x10 eyepiece lens and x4 objective lens?
Take a microscope slide containing some cells to practise your microscope technique. Observe the shapes and features of the cells.
A microscope has a x4 eyepiece and a x10 objective lens. What is the total magnification of the microscope?
When focusing, why do you turn the focusing knob so that the objective lens moves away from the slide?
A hair is 0.005 mm wide. How wide would it be if you looked at it with the lenses in Question 1?
