Below you will find many of the terms used in the "Microscope World" - or just simply in microscopy. Abbe Condenser : A specially designed lens that mounts under the stage and is usually movable in the vertical direction. The abbe condenser has an iris type aperture to control the diameter of the light that enters the lens system. By changing the size of the iris and moving the lens toward or away from the stage, the diameter and focal point of the cone of light that goes through the specimen can be controlled. Abbe condensers become more useful at magnifications above x. The condenser lens system should have a numerical aperture equal to or greater than the N.

First remove dust with a soft brush or can of compressed air. Then moisten a piece of dry lint-free tissue or lens paper and clean the lens surfaces with a circular motion.

Repeat with a second piece of paper moistened with lens solution if necessary. Repeat once again with dry lens paper until the lens is clean and dry.

How to Use Your Compound Microscope Set your microscope on a tabletop or other flat, sturdy surface where you will have plenty of room to work. If you have an iris diaphragm, slide the lever till the most light comes through.

See the diagram below for help locating these parts. Rotate the nosepiece to the lowest-power objective usually 4x for 40x magnification. It is easiest to scan a slide at a low setting, since you have a wider field of view at low power. Place a microscope slide on the stage , either under the stage clips or clipped onto the mechanical stage if your microscope has one.

A prepared slide works best when you do this for the first time. If you do not have a prepared slide, place a strand of colored yarn or thread on a blank slide and place a coverslip over it. Move the slide until the specimen is under the objective lens.

Adjust the large coarse focus knob until the specimen is in focus. Slowly move the slide to center the specimen under the lens, if necessary. Do this by nudging it gently with your fingers or by turning the slide control knobs if you have a mechanical stage. Adjust the small fine focus knob until the specimen is clearly in focus.

Then adjust the diaphragm to get the best lighting. Start with the most light and gradually lessen it until the specimen image has clear, sharp contrast. Scan the slide right to left and top to bottom at low power to get an overview of the specimen. Then center the part of the specimen you want to view at higher power.

Rotate the nosepiece to the 10x objective for x magnification. Refocus and view your specimen carefully. Adjust the lighting again until the image is most clear you will need more light for higher power. Move the x objective lens into position, and then slowly move the stage up until the lens makes contact with the oil.

Continue focusing with the coarse focus knob until the color or blurred outline of the specimen appears. Finish focusing with the fine focus knob. With the x lens, you will be able to see additional cell detail, but you will need to take extra care with focus and contrast for a clear image. When you are done using the slide, clean the oil off of the slide and the lens with lens cleaning paper and solution. How to Keep a Science Notebook. Designing a Science Fair Project.

Pollen is a small grain that consists of a few cells. To the naked eye it appears as a yellowish pale yellow dust-like substance that is either dispersed by wind or insects. Pollen is formed within the sacs or microsporangia in the anthers that are located in plant flowers. The development of plant anthers also involves the growth and differentiation of tissue that develop to produce the pollen sacs. This is then followed by a process of cell division meiosis that results in the formation of clusters referred to as quartets within the pollen sac chambers. The quartet then undergoes further divisions to produce pollen, which serves as the male gametophyte of plants seed plants for reproduction. Depending on the type of plant, pollen is either dispersed by wind or insect to the receptive stigma. This causes the gametophyte in the grain to develop a tube reaching the ovule of the flower, which in turn allows male gamete cells to be transported to the ovule for fertilization.

Using this information, students can then determine the sizes of unknown organisms. Microorganisms are important. Recent news topics have focused on a variety of microorganisms: E. Size is an important characteristic that students might investigate as they attempt to put these organisms into perspective. An understanding of the relative size of eggs and sperm can help students comprehend the relevance of structure and function in the design of each. When studying cells it is useful to be able to measure them. We can measure cells then make comparisons between different types of cells. Students don't relate to cell size because they don't have something to compare it to.
