4. Once the slides are dry, examine them microscopically. Be sure to use the 100× objective and oil. Microscope Use Protocol Viewing Your Specimen 1. Plug in the microscope, taking care to insure the cord is firmly attached to its back. 2. Turn on the power switch. Increase the brightness control dial until it is at its maximum position. 3. The total magnification of the microscope is equal to the magnification of the ocular multiplied by the magnification of the objective. If you are using the 10x objective and the 10x ocular the total magnification would be 10 x 10 = 100x. A specimen which is actually 1mm in size would appear to be 100mm in size when viewed through the microscope.

On your lab bench, set up your pipecleaners to represent a cell in G1 of Interphase. 2. Use the pipecleaner chromosomes to walk through each step of the cell cycle ‐ Interphase: G1, S, G2, and Mitosis: Prophase, Metaphase, Anaphase and Telophase. 3. Aug 07, 2013 · 3. Sometimes a participant in this lab has a response time that is less than 100 milliseconds. How might you explain such very short responses? Advanced Questions 1. Sometimes people find that a computer game they enjoy playing on a laptop or desktop computer is not as much fun on a tablet. How might the findings of this lab be related to Answer: White adipose tissue is composed of large cells with prominent central vacuoles. It is white because the lipid is washed away during fixation and the vacuoles appear white under the microscope. Brown adipose tissue has smaller cells with many lipid droplets and mitochondria. It is brown because of the large number of cytochromes present. The light microscope usually has three or four objective lenses on a microscope. They consist of 4x, 10x, 40x and 100x magnification powers. Magnification is a microscope's ability to increase size. When you magnify an images probability you may get blur images because of the useless resolution.A modern light microscope Microscopes are used to study cells. Modern light microscopes can magnify images about 1500 times, while electron microscopes can magnify images about two million times.
Rules for Microscope Use: 1. Carry the microscope properly. 2. Always begin focusing with the 4X objective. 3. Use the coarse focus only with the 4X objective in place. 4. Use immersion oil only with the 100X objective (oil immersion lens) in place. 5. Use only ONE drop of oil. 6. Lower the stage and then remove the slide when you are done. 7. Don’t use too much or the water will run off the edge and make a mess! 3 –Place the edge of the cover slip on one side of the water drop. You do not need to use the stage clips when viewing wet-mount slides! 5 –Place the slide on the stage and view it first with the red-banded objective.

A custom-made compound microscope (see the figure below) with an objective lens with a focal length of 3.60 cm, an eyepiece lens with a focal length of 6.05 cm and a barrel length of 25.0 cm is used to view a 0.100 cm specimen mounted on a microscope... These granules contain major basic protein, which is released to kill organisms too large to phagocytose, such as parasites and helminthes (worms). Eosinophils make up between 1 and 3% of the total white blood cells in the human blood. Basophils. Basophils are intermediate in size between neutrophils and eosinophils and have simple or bilobed ... This lab explores three common cancers. An additional form of cancer – Skin Cancer – used to be seen only in older individuals but is now seen in younger individuals, many in their early 20s. Skin cancer results from accumulated mutations to the DNA of skin cells, caused primarily by sun exposure. Step 2: Microscope Lens Care. Never touch any lens with your fingers. This leaves oil which is hard to clean and particles which may damage the lens. If a lens needs cleaning, use lens tissue, a lens cloth or a lens pen and be gentle. Do not use your shirt or a towel. Step 3: Microscope Parts. Learn the parts of your beginner microscope. The new LinkLabel Lab Printer brings a new level of freedom to laboratory labeling. The free, downloadable, Label Pro1M App, allows the user to endlessly customize and specialize their labels. Use the app to easily change text, font, positioning, size, and label length. The memory function allows you to save commonly used labels or templates. Apr 21, 2017 · In this lab, we will learn about the proper use and handling of the microscope. Objectives – Students will be able to: Demonstrate the proper procedures used in correctly using the compound light microscope. Prepare and use a wet mount. Determine the total magnification of the microscope. Explain how to properly handle the microscope.
