Let's say you placed the letter "e" slide on the microscope stage so that it is in the normal, correct orientation. You centered over the light source and under the objective. 1. How would it appear through the ocular lens after focusing? Describe what you would see. Click or tap here to enter text. 2. When you move the slide to the left with the stage controls, how does it appear to move through the ocular lens? Click or tap here to enter text.

Shown below are several micrographs (images from microscopes) that were taken using different microscopy techniques. Write down what method of microscopy was used and why you thought so. Choices for microscopy techniques are: Transmitted Light Microscopy (techniques of brightfield, phase-contrast, darkfield, DIC all fall under this), Fluorescence Microscopy, Scanning Electron Microscopy, and Transmission Electron Microscopy.

3. Please number these steps, in the order they should be completed when using a microscope. Remove specimen, lower stage, wrap cord, and return covered microscope to numbered shelf. Move to other objective lenses to increase magnification. Rotate lowest-magnification objective lens into position (probably 4x or 10x). Clean all lenses with lens paper. Place specimen on stage. Adjust chair to a comfortable height. Use coarse focus knob to adjust stage until an image is visible. Be careful to use only the fine focus knob with the longest objective lenses.

You have placed a microscope slide in a microscope and want to view it at with the 10X objective lens. List the steps that are necessary to set up and focus the microscope properly using the 10X objective lens.
A. Purpose: Figure 1 B. Materials: Microscope Magazine Slides and cover slips Paper towels Pipette Scissors C. Procedure: 1. Careful carry a microscope to your lab area. Make sure to hold it with one hand under the base and one hand on the arm as shown in Figure 1. 2. Plug the microscope in and turn it on. Take a moment to look at all the parts of the microscope. Then look at your ocular lens. What is the magnification of the ocular lens (eye piece)? Figure 2 3. Fill in the chart to show the total magnification for each objective lens. Magnification of Ocular Lens Magnification of Objective Lens Objective Lens Total Magnification Low Power Medium Power High Power
1. Match: Read about each microscope part. Match the description to the part on the diagram. Stage: Platform where a slide is placed. Eye piece: Lens at the top of the microscope that the user looks through. This lens most commonly magnifies a sample by 10x. Coarse focus knob: Large knob that moves the stage up and down to focus the sample. Fine focus knob: Small knob that moves the stage over a short distance to refine the focus. Objective lens: A second lens that further magnifies the sample. Microscopes usually have several objective lenses with different magnifications. Slide: A rectanqular piece of glass upon which a sample is mounted for viewing under a microscope.
Please answer the following questions (Question 1 AND 2) about compound microscopes. After clicking the objective into position, which adjustment knob(s) can you use to safely refocus the image? You may need to adjust the light intensity to better see the specimen. Indicate two ways in which you can change the light intensity?
