For the past few weeks at Smokey House we’ve been doing a bean experiment to determine if different music can change the growth of a plant. I used two very different genres of music, country and rap, and one bean with no music. I chose music because it was the easiest topic and plants do not hear things. People say that music can effect plants, but plants cannot hear. My hypothesis was that the music would not affect the growth of the plants.
I planted five beans, labeled two country, two rap, and one control. Two listened to rap music, two listened to country, and one listened to nothing. They each listened to music an hour every Friday in different closets, with the lights off, and the music playing at the same volume on each device. I measured the height of the stalk length every other school day. I gave them each a third a cup of water every time we watered them.
Country #1 grew better than the rest of them. It grew 16cm by the end of the experiment, rap #2 and country #2 didn’t grow at all, rap #1 grew 1cm, and the control grew 2cm.
I believe plant country #1 grew a lot more than the other plants because it was listening to country music. Because the country music is softer and not as verbally abusive towards plants. I was completely off on my hypothesis because the country music did change the growth of the plant, and the rap music changed the growth in a bad way and made it so it did not grow as much.
Next time, I would switch the rap to rock and see if it is the genre of music that affects the plants rather than. Water is another thing that may have affected the plant growth, and the density of the soil. We should have made the amount of water and how it gets water a controlled variable. The end.
