Science 9 Research Project: Water Fountains Vs. Toilets
Schools are one of the germiest places in the U.S., as well as all over the world. Diseases such as colds, influenza, pink eye and others spread rapidly in warm, moist conditions, which is why they thrive in schools. Kids touch just about everything and don’t know much about hygiene, and don’t clean their hands properly, which further causes the spread of these nasty germs and bacteria. This problem has been going on for a long time, and it is a battle that will continue to be fought. Among the germiest hotspots in schools is water fountains. Kids touch the button and drink the water, which comes from a spout that is covered in germs because of kids that suck or touch the spout with

Deadly viruses, such as Norovirus, spread this way. Germs can kill and make people extremely sick. When people get sick, many take days off and miss school or work. This way, they are missing out on valuable learning opportunities, especially with the block schedule that Poynette and many other schools have. Despite cleaning and disinfecting, people still spread germs and still die from bacteria. The reason we are doing this experiment is to find out where the germiest spot in the school is and what areas will benefit from the most extra cleaning.
Many, many viruses and bacteria are spread by touch. For example, if someone sneezes into their hand and then uses a door handle without washing or sanitizing their hands, they could transfer some of the deadly bacteria they have on their hand onto the door handle,

You will need 11.5 grams of Nutrient Agar mix, a flask, a stir bar, a hot plate, a polystyrene partitian sterile petri plate, and 500 mls of distilled water. You now have to combine the agar mix and the 500 mls of distilled water and mix together. Put the agar into the 500 mls of distilled water and make sure the stir bar is in the flask. Put this mix on the hot plate and bring to a boil. Make sure the agar mix is dissolved before removing from the hot plate. After pouring into the plates, close the lids on them to prevent condensation. Also important is to use plates within one day of making agar. Make sure to label the plates properly(name, date, swabbing area). What is especially important during swabbing is to use sterile cotton Q-tips and to make sure they are not contaminated. To do this, you should not touch the tip of the swab or put it in contact with anything besides the area being tested. This general rule should also apply to the plates. To swab, after collecting the sample, gently roll the tip of the swab against the agar in a zig- zag type motion, making large patterns. This will help you to achieve better colony growth. Make sure to place the lid back on the plates. After swabbing, place petri plates in 37 degree celsius incubator and let stand for 4 days, then record data. When collecting data, make sure to use qualitative and quantitative
When experimenting this lab on your own, there are certain methods and steps you need to follow. The first step is to make sure that you have all the proper equipment needed for sufficiency and accuracy. The following equipment is needed: E.coli, Sterile L-broth, three incubators, spectrophotometer, three scientific flasks along with three cuvettes
Use the cotton swab to streak the five labeled nutrient agar plates with the E. Coli K12 bacteria from the tube.
Is this school a petri dish? Here at Lowell Middle School we don’t enforce cleanliness and countless times I have seen people leave the bathroom without washing their hands. Therefore, I think that we should have an automatic hand sanitiser dispensers in every classroom, bathroom, and cafeteria.
Germs and many other diseases spread primarily through airborne particles, skin to skin contact, and or touching objects such as door handles, hospital buttons, or by sharing patient possessions. Nurses and other health care clinicians are constantly in physical contact with many different patients, who all have varying illness’ and diseases themselves. Many may also carry a
Touching objects, such as public phones or doorknobs, that have MRSA bacteria on the surface.
Contaminated surfaces in healthcare facilities are the main source of pathogens associated with HAIs. Pathogens can survive on the surfaces for several weeks facilitating their transmission through person-person contact 1,2. Surface contamination occurs by direct transfer through touching from an infected or colonized patient, or from healthcare staff carrying the pathogenic microbe on their hands. When a surface has become contaminated, a cyclical problem occurs because the microorganisms can be transferred to other surfaces and patients in the vicinity. While appropriate hand washing by healthcare staff can reduce the further spread of pathogens through hand-surface transmission,3 it cannot prevent surface contamination by the patient and
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.
After the plates are labeled, remove top agar from a 55 degree Celsius water bath. For each sample a 5mL pipette attached to a pipette is used to aseptically transfer 4.5mL of TA to the culture tube containing the bacteria. As soon as the TA is transferred into the tube, immediately pull it back up into the pipette and transfer the entire mixture to the corresponding agar plate. Do this for all the agar plates and their corresponding numbers. Make sure to use a sterile pipette each time something is transferred the mixture to avoid contamination. The TA starts to harden after a few moments, after it harden, invert the plate and store the plates in a 37 degrees Celsius incubator for a
Kissing, sneezing, sharing/ touching an object, such as a doorknob, soon after an infected person, you might be exposed to infection. Transmission occurs when you touch your mouth, nose, or eyes before thoroughly washing your hands. Germs can also be spread through contaminated blood products, medical supplies or sexual
It is very easy to get infected, if you touch a contaminated surface and do not wash your hands, you'll probably get ill.
Step are as follows; first, label two separate sets of spot plates. One for bacterial amylase and another for fungal amylase on each plate write the differentiating temperatures beginning from lowest to highest (0C, 25C, 65C, and 85C), temperature are as implemented by lab director. On the side of each plate label the time periods, ranging from 0 to 10 minutes in two-minute intervals. Next, four test tubes should be filled with bacterial amylase and labeled with a B, and another four with fungal amylase and labeled with an F. After five minutes, use plastic pipettes to gather some enough starch from SB (starch bacteria) from each temperature and place three drops into the 0-minute row wells. Then add 3 drops of iodine to the equilibration.Following, remove and place each grouped and labeled test tubes correctly labeled B and SB from each temperature and place them in their respective environments for five minutes to equilibrate.
by airborne respiratory droplets for example, coughs or sneezes, by skin-to-skin contact ,handshakes or hugs, by saliva which is kissing or shared drinks, and by touching a contaminated surface for example, blankest or doorknobs.
The subtle number of highly contaminated water systems has recently been infiltrated with the growing number of 2,000. Since the horrific incident in Flint, Michigan, many people have began their own research across all of the states in the U.S. Unfortunately enough, most of the places with the highest contaminated water systems, were schools. With these numbers growing on a daily and the main people enduring the hazardous water is the children, this has introduced a problem for everyone. The water must be sanitary and safe for everyone at all times, therefore the promotion of clean and non-hazardous water is what the people must strive for. With the interference of unsafe pipes and several dilemmas throughout the year, it is much more secure
Another kind of disease exposure are Air Borne disease like T.B. (Tuberculosis), influenza, etc. These pathogens are spread through air; by coughing or sneezing of the infected person. These pathogens travels a long distance in the air and the nurses taking
There are five characteristics of the innovation: Relative Advantage, Compatibility, Complexity, Trialability and Observability. Sanitation is obviously better than non-sanitation for reducing contagious diseases, which refers to Relative Advantage. Compatibility could be the most influential factor for the failure, because sanitation is not compatible with the intended users’ perceived needs or value that boiled water is
