our worms under the microscope. To make the viewing chamber we had to use about 12 wax like parafilm sheets on a slide. We made sure each of the sheets fit on the slide‚ and stacked them up to make sure that the worm could not get out. We used a heating plate to melt the parafilm sheets but we had to be careful not to let the slide get to hot because it would burn. Using a razor we had to cut out a trough. This is where the worm would sit in so we could view it under the microscope. Our teacher has

Score 1. How do you calculate magnification on a microscope? Answer: The shortest lens is the scanning objective; you use it to locate the object on the slide. The medium-length lens is the low-power objective. The longest lens is the high-power objective. Multiplying the power of the eyepiece lens and the nose piece lens gives you the total number of times an object will magnified. (4 points) Score 2. Explain how to focus a microscope using the high power lens. Include any safety issues

Effect of Caffeine on the Heart Rate of Daphnia Daphnia are extremely small aquatic invertebrates. They are transparent‚ so you are able to see their internal organs; this means it is easy to monitor their heart rate by observing them through a microscope [1]. Physiological results from caffeine consumption include the stimulation of heart rate‚ blood pressure‚ metabolism‚ body temperature and alertness. [2] In this practical investigation the aim was to determine whether the hypothesis that caffeine

and Blood Abstract The purpose of this exercise is to gain knowledge on basic skills to correctly operate a microscope by viewing blood and bacteria through different magnifications Hypothesis This exercise will help me gain knowledge and the correct way to use a microscope. This will also help me for future observations of microbes. Methodology Properly set up microscope and made sure it was functioning properly. All lenses were wipe with lens paper and nine different slides were chosen

Title: Observing Bacteria and Blood- Lab #1 Purpose: Being able to learn how to correctly use a microscope and the oil immersion lens to be able to see the prepared slides. Also to learn how to prepare my own yogurt and blood slides. Procedure: First‚ set up the microscope. Clean the ocular lenses and objectives with lens paper. Then pace the prepared e slide on the stage and make adjustments. Turn the rotating nosepiece until the 10x objective is above the ring of light coming through the slide

prepared by placing a drop of water on a glass slide. A very small piece of the Elodea is placed in the water and covered with a slip cover. The slide was then placed under the light microscope and observed for cell shape‚ and identifying the different organelles evident in the plant. The slide was kept on the microscope stage until it became warm. After a few minutes the slide was observed for the movement of the chloroplasts. The movement of the chloroplasts was also recorded.

medicine‚ many innovations have occurred that impacted the world and vastly transformed the future of medicine. In my opinion‚ the four most important innovations in medicine are Vesalius’s book and view on anatomy‚ inoculation and vaccination‚ the microscope‚ and MRIs and CAT scans. The 16th century contained some of the greatest innovations of all time; one in particular was Vesalius’s anatomy book‚ De humani corporis fabrica. Vesalius’s book was the first medical book in which illustrations were
