This experiment illustrates the importance of handwashing and proves that hand washing is worth it. Since our hands are constantly coming into contact with ourselves and others, touching surfaces, grabbing objects, being sneezed into, etc., keeping our hands clean is one of the most effective, yet simple way we can take to avoid getting sick and spreading germs to others. Many diseases and conditions are spread by not washing hands with soap and clean, running warm water. “The human skin is a host to anywhere between 10,000-10,000,000 bacteria per square centimeter and since health care providers come into contact with pathogenic bacteria by being engaged in patient care, hand washing can reduce the risk of spreading diseases (page 3).” The objective of the experiment is to test the effectiveness of hand washing and demonstrate normal flora. This report presents the procedures and materials for the experiment, the experiment's results, and an analysis of those results.

8. I added the 3 ml of soap to the beaker and stirred the solution 40-50 times with a fresh pipette.

This project may improve my health by exposing me to all sorts of bacteria. When I am exposed it will help to strengthen my immune system. Plus, I won’t be as disgusted by messy trash after I have completed my project. Generally, when I become sick I get really sick, so this project should help with the severity of possible future illnesses. I believe this project could strengthen my immune system, since trash has lots of bacteria on the object.

Hypothesis correct?: Yes and no. The tap water did soak up the color best, however the plants in soft water and the reverse osmosis

The data for Pond 5 were taken first on August 5th, with a temperature of 85.5°F, and wind was headed in a northern direction. Since Pond 5 is quite deep, the group took a small boat out into the middle of the pond about 15 feet away from the shoreline where the water is clear. The data for Pond 3 were taken on August 10th, temperature at time of experimentation was approximately 79.3°F, and wind was northerly. The group walked through the pond to the north of island 1 (Figure 2) and obtained the samples.

To help the prevention of infection spreading is by knowing the method of washing your hand because we carry most bacteria sue to the open air that we come in contact with. For example we use are hands to shake hands with someone holding or touching objects. When you are performing any form of hand hygiene you will need to make sure that you have washed your hand with anti-bacterial liquid soap; this is to help prevent any bacteria which we already have on our hands. In all health and social care settings an automatic liquid dispenser should be placed so that when washing hands any individual doesn’t touch or need to even sneeze any part of the liquid

Testing the Effects of Bacteria Growth on a Non-Treated Vs. Treated Hand Name: Laura Torres Biology 1407-P Abstract The objective of this experiment was to test the effects of bacteria using a treated hand and an unwashed hand. Two plates of agar and a hand is used to retrieve the bacteria and then placed in a temperature where they can survive. Different types of bacteria are affected by the environment that slow down or increase the growth of these prokaryotes.

Life table studies are predominantly used by researchers as a technique for estimating the growth of populations and forecasting the size of a population. The life table supplies a Full description includes the specifics of development times, the survival rates of each growth stage, and the fecundity and life expectancy of a population Yang et al. (2013). Host plant species are an essential agent in the outgrowth of Mealybugs; the development of the mealybugs was considered as a symbol of the goodness of that host plant to avail as a food exporter for its development. Most of our results are in assent with Patil et al. (2011) and Rashid et al. (2012).

Generally, I consider myself to be a more sophic person. As a prospective accounting major, I tend to lean on fact and reason when making decisions. When given time alone, I ponder. When faced with a decision between two or more options (such as my recent purchase of a new phone), I heavily research and weigh facts. High blood pressure and anxiety are very present in my family and I feel like that contributes to my not being entirely in touch with my emotions—often what I feel is irrational or made up by my mental and physical struggles. However, in decisions that will determine my atmosphere (such as what school to attend) I tend to look inward with a more mantic approach. My first prospective college apartment was decided through my usual weighing of facts and reasons, but when I went to visit where I could potentially be living it did not feel right. All the facts made sense to me but I focused instead on what I felt. Still, my life in general is conducted in a more sophic manner.

In the experiment, it was tested that bacteria will be most effectively eliminated when using hot water during the hand washing procedure. It was predicted that if the subjects use a higher temperature of water while washing hands, then the percent decrease of bacteria will be greater in hands washed in hot water as compared to those washed in cold. In the experiment, two groups were created one being the control group made from two test subjects and one other named the experimental made from 3 test subjects. The control group was the group that used soap and normal(room) temperature water, while the experimental used hot water (110-120 degrees).

Introduction: Blood is a fluid that is transported through the heart arteries, capillaries, and veins. It is a liquid connective tissue that is responsible for transporting nutrients and wastes to various cells in the body. It is referred to as “River of Life” for its many roles including protecting the body from pathogens and carcinogens, from blood loss, and from imbalances pH, temperature, and homeostatic conditions of fluid balance. There are two basic components of blood including plasma and the formed elements. The plasma is the liquid in the fluid component of the blood consisting of mostly water and the solutes within the blood.

Biodiversity presents occurrence of variety of species and their natural community in which they live. By the definition it is “The degree of variation of life forms within a given species, ecosystem, biome, or an entire planet. It is a measure of the health of ecosystems and is in part a function of climate.” (Rutherford) Ecosystem is on the other hand, “ community and its abiotic environment”( Rutherford). Biodiversity exists in every ecosystem, weather it is big one, or just ecosystem of one garden, it has the same importance because without it nature loses its ability to perform major functions needed for life on Earth, as it is oxygen production. Trough this investigation, two different ecosystems will be explored and

A defensive strategy is important when trying to avoid infecting oneself with an illness lying in wait (Wisegeek.com, 2011). According to Mayo Clinic (2009), frequent handwashing is one of the best ways to avoid getting sick and spreading illness. Although it is impossible to keep hands germ-free, washing hands frequently can help limit the transfer of bacteria, viruses and other microbes.

This assignment will encompass how the results of the personal hygiene and susceptibility microbiology experiments provide a framework for the basis of the NICE Clinical Guidance (CG139) on Infection and how crucial the reasons for the hand wash protocol and hygiene is in all healthcare settings.
