Pictures of green bean seeds over duration of the experiment:

Set-up A: set-up with pop music played

Set-up B: set-up with classical music played

Set-up C: control. Set-up without music.

Day 1: start of the experiment 

Day 1 results: 

- A : 0

- B : 0

- C : 0

Day 3: 

Top left: A      Middle: B    Top right: C

For safety issues, the containers were brought indoor while the earpieces were placed inside set-up A and B ( during the 'music-hearing' session) . After the music was played for 1.5 hours, the set-ups were then placed outdoors again for sunlight. 

Day 2 results:

A: ( 5 + 5)/ 2= 5mm ( average of two plants) 

B: 0

C: 0 

Day 4: 

Set-up A. The seeds on the top and top right hand of the container have germinated.

Set-up B. No seeds germinated yet

Set-up C. No seeds germinated yet.

Day 4 results:

A: ( 5+ 15)/2 = 10mm

B: 0

C: 0

Day 5: 

Set-up B. One seed germinated

Set-up A


As there was still no sign of germination for set-up C, it looked the similar to  previous days,  hence no pictures were taken.

Day 5 results: 

A: (60+ 20 )/2 = 40mm

B: 10mm

C: 0

Day 6:

From top to bottom: set up A, B then C.

Day 6 results:

A: ( 105+ 25)/2 = 65mm

B: 15mm

C: 2mm

Day 7:

Set-up A

Set-up B

Set-up C

Day 6 results ( final):

A: (150+50)/2 = 100mm

B: 15mm

C: 2mm

Pictures of 'Music hearing' session

- I used earpiece instead of blasting the music soundtrack on a music player

Why? 

Due to space constraints in my house and to keep the set-ups all in the same location throughout the experiment, I decided to use earpieces instead of playing the music 'freely'.

- Using earpiece would allow only the setup the earpiece is placed in to receive the sound wave, as the music played through the earpiece would travel a shorter distance and only objects that are close enough to the earpiece would be able to ' hear the music' as compared to that of the same volume when the music is blast from the music player. Hence, it would not affect the experiment results as the set-up only receives its intended music genre and not a mix of different sound waves from the other set-ups. 

- Using earpiece would also allow me to control the specific direction of the sound wave as I am able to twits and turn the earpiece such that it is directly facing the plants and the plants would receive the maximum sound wave possible. However, if i were to use a music player, most of the sound wave would have traveled to the surroundings instead of directly towards the plant as the music player would be placed at a certain distance away from the set-up

Evidence to show that Pop Music has a higher frequency than Classical Music in general.

Top column: Classical Music
Bottom column: Pop Music

Using a software, Audacity, I measured the frequency of both Classical Music and Pop Music and compared it with each other. As mentioned in my report, due to the nature of the genre of music, Classical Music tend to be softer and has a small amplitude as compared to Pop Music of the same volume on the music player. 

I did this experiment using Audacity under :

Constant variable: 

Volume of the music played 

Device used to play the soundtracks

Surroundings which the experiment of both soundtracks were tested.
