24 Remove the letter "e" slide from the stage of your microscope. Return it to the same slide tray you had taken it from. Obtain the slide with crossed colored fibers 25 Place this slide on your microscope stage. Using a scanning lens, take a look at the region where the fibers overlap. By zooming in and out of focus, determine which fiber is on top and which is on the bottone Color of the uppermost fiber: Color of the fiber on the bottom: 26 Remove the slide with color fiber of your microscope. Return it to the same slide tray you had taken it from. Activity 3: Microscope Storage 1 After you finished your observations, remove the slide from the stage. Return it to the same slide tray you t had taken it from. 2 Important: All microscopes have to be stored properly. Here are the rules you should follow every time you finish using microscopes: a Do not leave a slide on the microscope stage. b Clean the stage and the objective lenses if necessary. Always use lens paper and cleaning solution to clean microscope objective lenses. c Lower the microscope stage all the way down. d Turn the scan lens, the one with red ring around it, into the working position. e Wind the electrical cord around the arm of the microscope. f Return the microscope to its proper (numbered) space.

see 22 Change the scanning objective lens (4) to 10x by rotating the nosepiece (3). Diagram what you see in the field of view, indicating the total magnification. 23 Change the objective lens (4) to 40x. Diagram what you see in the field, indicating the total magnification. O Magnification: Magnification: 40x Magnification: Is the image upside down and/or backwards in comparison to what you saw with your naked eyel What happens to the field of the microscope with an increase of the magnification? Look at Figure 3.3. In the circle on the right, draw what will happen to the letter "e" if you did not center the specimen as you increased the magnification.
