CSB #8 Experiment: Musical Stimuli Affecting Your Heart Rate


Little Scientists: Savi Joshi, Tiara Bhatacharya, and Delaney Martin


Music is an important influence in many teenagers’ social, academic, and physical lives. For some, it encourages focus on tasks such as homework or extracurricular, such as athletics; for others, it is a reliable source of comfort and a break from the stress caused by school. However, some songs prove to be better at helping students focus and promoting intellectual capabilities. For instance, it is a common perception that classical music helps infants make good bases for learning in the future. Although many believe this, we were curious to see if music actually affected the brain and heart.

In this experiment, Delaney, Tiara, and Savi tested how would the heart react to the different styles and tempos of music. We used 5 songs: New World Symphony (Dvorak), Always (Panic! At The Disco), Levels ID Original Mix (Avicii), Louder: Doctor P & Flux Pavilion Remix (DJ Fresh), Let's Go ft. Yelawolf, Busta Rhymes, Twista, and Lil Jon (Travis Barker). We were looking for a change of heart rate or a spike in the heart beats. If a person were to listen to high tempo music such as Let's Go or Louder, their heart rate would be higher than while listening to New World Symphony or Always.

We used logger pro to record the heart rate and the heart beat. We tested our experiment on Delaney, Savi, and Tiara.

Savi intensely listening to music while Delaney uses the assistance of Logger Pro and the EKG to record data.

We found our that our initial hypothesis was correct, but with exceptions. The music did not affect Savi at all. We think this is caused by her familiarity with these songs, meaning she would be used to the tempo of the music. Whereas Tiara only identified with the classical music, calming her down significantly. Delaney was affected by the music the "best" and responded to almost every song.
The top graph represents all three of the runs overlapping. The next represents Savi's response to the music. As noticed, all though her heart rate is high, due to some error, it maintains to stay the same along with her heart beat. The blue represents the 2nd run with Tiara as the test subject. Whereas, Tiara also with a more stable heart rate with slight fluctuation became excited when New World Symphony came on. When the music started, her heart beat would spike but eventually calm. As seen, during the 30 second intervals of silence her heartbeat was stable. Last, the green represents Delaney. Her heart rate fluctuated all over during the course of the experiment, but her heartbeat was only affected when she was introduced to Let's Go in the beginning and Louder towards the end.

To conclude, the effect music has on a subject depends on the subject's preferences and their familiarity with the music. Throughout all three runs, one fact remains the same: classical music caused stability in heart rate and a calm heartbeat.

CSB #7: Video Games Now Being Used as a Cure

Recently, scientists have started to study whether kids with cystic fibrosis can use video games as motivation for them to stick to their treatments. Cystic fibrosis is a disease that causes mucus to build up in the lungs and airways of the body, which makes it extremely hard for the infected person to breathe. One treatment for kids with cystic fibrosis is "huffing", which is heavy breathing that helps get rid of the buildup. A problem with this treatment, however, is that many children would rather do something more fun instead, such as video games. Because of this, scientists have tried to link video games with their treatment, and created a study to see if active video games, such as Wii Fit and Wii Sports, will help with their treatment. The way scientists set up the experiment is by comparing the amount of breathing the children did when playing video games, versus not playing them. For 2-4 weeks, kids would be around video game equipment, but not be able to play the video games, and scientists would record how much they followed through with their breathing therapy and how effective it was. Then, for the same amount of time, kids would be allowed to play video games and the scientists would record and compare the results to the non-video game time period. They used spirometers to record how much air their lungs could contain and compared the volumes before the study, during the non-video game time period, and the time period when the children could play video games. After scientists received the results from the study, they concluded that participating in video games does in fact help children stick to their treatments. However, scientists did not know if it was merely the presence of the video games that made patients stick to their goal more or if it was in fact the activity from the video games.
If scientists can figure out a way to get children to utilize video games, and possibly other technology, for treatments, many diseases will become much less of a nuisance. It could even help many more people survive because they will be more focused and motivated to stick to their treatments. In addition, scientists may be able to come up with new and more effective treatments for diseases that were thought to be incurable. This will make many diseases less of an issue so that doctors can focus on more important issues, and it will allow patients to be not as inconvenienced. This breakthrough is important to medical science as it will help many children suffering, not just those with cystic fibrosis.
