How Can Hypothesize Women's Restroom Soap Dispenser

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.

Analysts have been concentrating among the dynamic parts of supportive microorganisms inside the human body, and they found out that: “In fact, most of the cells in the human body are not human at all. Bacteria cells in the human body outnumber human cells 10 to one.” (Jennifer Ackerman, 2012, p. 38) Ackerman also expresses that

The article “Some of My Best Friends are Germs,” by Michael Pollen was a very interesting and informative read. Pollen explains that our bodies house 100s of trillions of microbes. More than 99 percent of our genetic information is microbial. The large number of bacteria that inhabits us weighs many pounds, forming a massive, unexplored world that scientists are just starting to document. These bacteria affect our health as much as if not more than the genes we receive from our parents.

In this experiment, we wanted to investigate which surfaces in the school had the most bacteria, and we thought that the surfaces used more would have the most bacteria. For this experiment we used agar plates, cotton swabs and distilled water in order to see how much bacteria was on each surface. Cotton swabs were wet with distilled water and then the swabbed ws wied on a 2 inch space of the surface and twisted to cover the entire swab.once we swabbed the surface, we wiped the swab on the plate in a zigzag motion holding it upside down. The girls bathroom sink handle had 389 bacteria, and the boys bathroom by the football field had 0. We saw that places commonly used such as the bathroom sinks, door handles and railings contracted the most bacteria.

Before, biologists assumed all microbes are bad for the human body (automatically thought of pathogens), caused many diseases and harm our body fundamental systems. In addition, the biologists think that our body is already built which had all the functions required to maintain our health. However, the attitude has changed over the last decade. The biologists characterized the most prevalent species of microbes in the body, and found out that these collective microbes do not threaten us, and they also are important part of human bodies.

There are major effects in the United States and Europe to help identify the role of microbial communities in the human body. The colon requires a balance of microbial agents that assist with various functions of the body. An imbalance can lead to C.diff., irritable bowel disease (IBD), irritable bowel syndrome (IBS), neurological disorders, and obesity just to list a few. Many of these problems have grown to an epidemic proportion. Both the United States and Europe have started projects aimed at the microbial communities of the body and their roles in our health.

The human microbiome has received more attention in the last few years as scientists have begun to link health and mental wellbeing with these internal synergists. Murray and Manary (2015) define a microbiome as an “ecological community of commensal, symbiotic, and pathogenic microorganisms living inside the body…100 trillion organisms, including anaerobic bacteria, archaea, yeast and parasites.” Humans are born and immediately exposed to these microbes, creating their own microbiome within hours. The natural birth baby inherits microbes of the mother and caesarian section babies receive microbiota of those who handle them first (Ley, 2006). Genes, and the environment from which they are born into, shape their future microbiome (Ley, Peterson,

When reflecting back to experiment 3, Aseptic Technique and Culturing Microbes, I realized the large amount of microorganisms that can be found in everyday life. Many different types are found with in the human body. Theses experiments focused on two types of bacteria. First was Staphylococcus epidermidis, found on the skin, and second was Lactobacillus acidophilus, found in the gastrointestinal tract. Both have similar needs for growth when it comes to temperature, however, different growth environments are used.

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.

Since our early childhood we have always kept that inner voice in the back of our minds telling us not to touch certain things or to follow certain rules so we don’t become infected with germs or become ill. Our mothers and fathers kept a watchful eye on us as children and especially as toddlers because of our very curious minds and our driven power to explore. We continue to set the same rules for our younger siblings and will probably act the same as our parents did when we were young to our offspring. Well one individual named Jack Gilbert a father of two that studies microbial ecosystems at the University of Chicago decided to put these assumptions to the test.

In our world we are surrounded by microorganisms, some are harmless, many are beneficial; they are a part of our normal flora on our skin and in our intestines, providing a barrier against microorganisms that may not be so harmless. It is important, however, to distinguish which microorganisms are potentially pathogenic from those that are not, and when someone does get ill to determine what the organism is so appropriate treatment can be determined.

The result of this experient shows that lunch meat grows more bacteria than Skittle and bacteria does grow more if we drop it. In the result of lunch meat, tile floor grows the most bacteria and for the Skittle, bacteria grows more on the cotton cloth. During the experient, I find out that it’s interesting that after 12 hours, that control sample for lunch meat grows more bacteria than the lunch meat on cotton cloth.

This project involves testing various disinfectants on bacteria covered toothbrushes to see which method is most effective. The three main methods of disinfectants are hydrogen peroxide, U.V rays to kill bacteria, and antibacterial soap. Learning what is in the various disinfectants that eliminate bacteria is beneficial to understanding the experiment. Bacteria are single-celled organisms that reproduce quickly. Pathogens are bacteria that cause sickness. Once the body is infected with pathogens, those bacteria reproduce and grow inside of cells in the body. As they grow, certain bacteria can make toxins; those toxins can damage the body’s cells. Symptoms of a sickness

During this project, we tested if washing your hands multiple times would affect the bacteria growth on your hands. I think that the more you wash your hands, than there would be less bacteria growth each time. This experiment will help to show us just exactly how the bacteria on our hands if affected as we wash them. This way we will be able to see the bacteria better because a single bacteria would need a microscope to be visible to the human eye. Since I wiped my finger on the agar plate, the bacteria will grow fast and will start to form colonies of bacteria. After the bacteria forms colonies, you won’t need a microscope to be able to see the bacteria. This will show us how washing your hands can keep you from getting sick or spreading a sickness you already have.

Life on this planet began with microorganisms. Through millions of years microorganisms have found ways to successfully adapt and survive. These adaptations have created a wide biodiversity, allowing them to basically populate in all places. Why are these microbes so important? Because they shape the history of our world. Some microbes can be deathly to humans while some others are favorable, for example, bacteria that lives in the gut of both humans and animals and helps during the process of digestion (Alfred Brown & Heidi Smith, 2006). Understanding these interactions help scientists to find ways to protect humans from potential deathly pathogens. In order to observe microbes, microscope proficiency and microorganisms’ identification are crucial skills in a microbiology lab. During this laboratory session, samples of environmental and human organisms were inoculated into two different rich media and incubated to their according temperature. After this, appropriate use and calibration of the microscope was performed. Lastly, morphology and size of different species of bacteria, algae, fungi and protozoan were recorded.
