Per.3 Musics Effect On Bacteria Growth Not so long ago in June 1, 2010, a sewage plant near Berlin put an orchestra to play for the microbes. This is a very surprising thing, but the waste treatment facility in the town Treuenbrietzen decided to do this,because they thought it could make microbes work faster and reduce their energy cost. The process was developed by Mundus, a small German firm-headquarter in Wiesenburg,Germany. Anton Stucki, a founder and manager of the firm helped come up with the idea that if Mozart has a good effect on microbes, too. As a result, this experiment, waste water facilities will be able to save energy costs and decrease the amount of residual sludge, which is very expensive to dispose. As a final point, th experiment is to test if bacteria or microbes will grow or not with music variation in a very close distance. Problem Statement Background Information Does Music Alter The Growth of Bacteria? Procedures Cont'd 8.Connect the headphones to the music players and play a different song for each.
9.Let the samples grow for a week and make sure to take pictures of the bacteria developing bacteria every day.
10.At the end of the week, take off the headphones and compare each sample. Also, take notes of the amounts of colonies in each sample and measure the size of each colony.
11.Finally, carefully dispose the petridishes DATA ANALYSIS As a result, this experiment was conducted during a period of 7 days, two samples of bacteria had music and one. The bacteria was gotten from a door knob in my house. The purpose of this experiment was to see if any type of music could affect the growth of bacteria. During the first three days not many colonies were found in each sample, until the fourth day. The petridishes contained agar solution, which was used for the growth and development of bacteria. The sample with the most bacteria was the third sample, that didn't have no music playing next to it. However, the first sample had the second most amount of bacteria and had music playing next to it. At the end, my hypothesis was supported by the data and observations gathered. Applications The reproduction of bacteria can help reduce the
energy cost of waste management companies, because
bacteria has the ability to break down many types of food,
which in many places is very expensive to get rid of. Bibliography http://www.stevespanglerscience.com/experiment/growing-bacteria

http://www.youtube.com/watch?feature=player_embedded&v=6-chXVgu8Z.0 Hypothesis IF any type of music is put close to a bacteria, THEN the bacteria will no grow or spread into colonies, BECAUSE the vibrations or beats of the music will keep the bacteria from doing anything. Materials 3 petridishes
agar solution
Rubber gloves
2 portable CD or mp3 players
2 pairs of cheap headphones
Camera
Notepad
A play list with several songs Procedures 1.Prepare all materials.
2.Wearing rubber gloves, prepare the petridishes.
3.Using the sterilized swabs, collect bacteria samples while wearing gloves from places like a faucets or door knobs or any other place that people touch a lot . However, make sure that you get the bacteria from the same place and same type of bacteria.
4.Then, swipe the sterilized swab on the agar of the petridish and close and seal the dish.
5.Remember to label each sample.
6.Place the samples in a warm place, and leave one sample alone, this would become the control.
7.For the other two samples, place the headphones snugly around the dishes. Variables & Control Experimental Group: The samples with headphones and music playing.
Control Group: The samples with no headphones and no music playing.
Independent Variable: Music vs. No Music
Dependent Variable: The growth of bacteria while different songs play.
Constant: The Headphones, the petridishes, and the mp3 players DATA DATA DATA Sample 3 without music Sample 2, with music sample 1 with music Recommendations To make this experiment better, the researcher could of
used more samples, and bacteria from different places.In addition, the researcher could of let the experiment for a longer period of time, and also have music from the
same genre and not different types of genres. The lab entitled Music's Effect on Bacteria Growth was about finding out if music can affect the growth and development of a bacteria. The purpose of this lab was to observe if music can allow bacteria to grow faster, or slower. The procedures used to conduct this experiment were preparing the agar to have something to hold the bacteria with. Afterward , gather bacteria from the door knob with a cotton swab and swipe it in the agar. Finally, cover the Petri dishes and put the headphones really close to them and allow music to play nonstop. These major steps led to an experiment with music versus no music and is expected to cause change in the growth of bacteria, because music will not allow bacteria to do anything. Furthermore, all other variables such as the Petri dishes, the headphones, and the mp3 players were kept constant. The major findings in this experiment were that music does affect the growth of bacteria and the experiment was conducted during a period of 7 days with music playing nonstop. The data consisted of manipulated data, because it was manipulated when two bacteria had music and one didn’t. Upon analyzing the data it was determined that the data supported the hypothesis. When compared with other researchers the findings indicate that music doesn’t allow bacteria to grow, due to the fact that the vibration of the music doesn’t allow the bacteria to thoroughly think good enough to keep reproducing as usual. The hypothesis was therefore supported. The application of this lab in society is that it can help reduce energy cost in the many waste management companies even if the process is slower than usual when music is present. Findings in this lab have many applications including having less bacteria in places where people touch a lot when music is present. In addition, the concepts learned in this experiment were that we should be more aware of the amount of bacteria present in our surroundings , and that of course music is a fun and safe way to prevent them from reproducing. The method in this experiment can be improved by having more samples present , collecting bacteria from different places , and also conducting the experiment for a longer period of time. This experiment/research is really awesome and it is worth the wait. The hypothesis was therefore supported.
