How Does Music Affect Bacterial Growth?
Transcript of How Does Music Affect Bacterial Growth?
Science Fair Project
Bacterial Growth & Music
What music does bacteria enjoy the most?
Problem or Question
Music not only affects our mood and emotions, it also affects the growth of bacteria.
Music cannot hear, but it is responsive to vibration patterns in music.
Ties into the Mozart Effect, a theory that playing music from Mozart can grow bacteria, plants, improve health of babies, and even the production of milk.
Research or Background Info
Our hypothesis states that if classical music is played for a certain amount of time, we will observe a faster growth of more quantities in the bacteria because of its slow rhythm, beat, and pattern of vibration.
1. wearing gloves, prepare the petri dish.
2. using the swabs, collect bacterial samples.
3. place the samples in a warm, out of the way place.
(leave one alone, control)
4. for the others, place the headphones around the dish.
5. connect the headphones to the music players, play a different song/ album on repeat.
6. let the samples grow, leave music playing for 8 hrs a day.
7. take pictures of the growing pictures everyday.
8. carefully dispose the petri dishes carefully.
9. analyze the data.
Procedure for Experiment
Week 1: 3 colonies
Week 2: 9 colonies
Week 3: 15 colonies
Week 1: 6 colonies
Week 2: 15 colonies
Week 3: 24 colonies
Week 1: 2 colonies
Week 2: 5 colonies
Week 3: 12 colonies
Pictures from Experiment 1 (Before)
Pictures from Experiment 2 (After)
Analysis of Data
What To Do Next
Final Amount of Bacteria Colonies:
Jazz: 15 colonies
Classical: 24 colonies
Rock: 12 colonies
Our conclusion was that classical music, as predicted, was the music genre that showed the most results in growth of bacteria. Next came jazz music which was still more than our last variable, rock music.
I believe that the next step for us to do after completing this experiment would be to continue to research the ways that using music has impacted the health and growth of many things around the world.
-2 or more petri dishes
-rubber or plastic gloves
-2 or more portable CD players
-several pair of headphones
-several songs/ albums of a variety of music
-notepad and paper
Risks & Safety
Since the bacteria will stay on the petri dish, and it is a non-pathogenic, there is little to no risk. Dispose of them properly by soaking them in 10% bleach for a few days.
