How do different tempos effect the human mood and heart rate?
Abstract:
We got the motivation to do this project because we were hoping to be able to study brain waves and psychology but that would have been really hard to measure so instead we decided to try something a little different for our experiment. We tried to answer the question of if tempos could affect a person’s heart rate and/or mood. We thought that as the tempo went up our test subject’s heart rate would go up as well. Instead as a result most of our test subject’s heart rate would go up and down but there was no dramatic difference until we turned the last tempo off most subjects heart rate would shoot up dramatically after the tempos went off.
---------------------------------------------------------------------------------------------------------------------------
The topic of our experiment is to determine whether different tempos can affect human moods or their heart rate. We are doing this experiment because we would like to understand if types of music or music tempos will change a person’s mood or how they are feeling. Then if we understand this we can listen to a certain type of music at a specific tempo to change our mood for the day. In our experiment sound waves are essential to our experiment because they are the sound made that travels through a medium to our test subject’s ear. The tempo that people will hear will travel with the sound wave to the ear. The tempo could also affect psychology, or how a person feels or thinks. Human beings can distinguish a range of tempos from around 40-300 beats per minute. The golden mark is about 119.80 beats per minute. Our prediction for the outcome of this experiment is that the higher the tempo is the faster your heart beat will be and you will become happier. So our question is if different tempos can affect human mood and/or heart rate, then our hypothesis is we believe their heart rate will go up and they will become happier as the tempo goes up.
In our experiment we used a heart rate monitor that goes on the finger and a metronome for the four different tempos for people to listen to in order to determine whether heart rate or mood will change while listening to different tempos. We will set the four different tempos for people to listen to, which are 40 BPM, 80 BPM, 120 BPM, and 200 BPM. We will first have our test subjects take a survey so we know how they are feeling before the experiment, and we will check their heart rate. We will then let the tempos play for 30 seconds each, take their heart rate, then change to the next tempo. After we go through all four tempos they will retake the survey to see if mood has changed at all.
The results of the experiment were unexpected. We found that people heartbeats skyrocketed after listening to the tempo. We also found that their heartbeats were slower, indicating calmness, during the tempo’s playing. The experiment was done because we wanted to do something to do with brains and reactions to sound waves, but brain waves are too hard to track, so we decided on something easier to measure. We expected to have the heartbeat go up when the tempo went faster, but that isn’t what happened. We have learned that tempo can affect a person’s heart rate.
We found out that people's heartbeat goes up dramatically once the tone turns off. For most of the tests, the heartbeat went down then up then back down. People moods got happier, for the level meter went up by at least one point. With Chloe’s results, her happiness went down due to the weather. Her calculations were not used in the results of this experiment.

Rube Goldberg
In this project, our task was to build a Rube Goldberg machine. A Rube Goldberg is a machine that uses many different steps to have one final action. Usually mechanical, these machines are a lot of fun to build. For Physics, I had on my team only Chloe Stein and I. That meant that instead of the optional three, we had only two. I didn't realize at the time that that would mean that I would have less resources, fewer ideas, and less of a sense of direction. Thankfully, this project was not a competition, because Chloe and my Rube Goldberg was, unfortunately, a collosal fail. On exhibition night, it didn't even run. The day before, it had collapsed due to poor material quality and lacking refinement. It was an embarrasing predicament, and one that I never intend to repeat.
In the Rube Goldberg, we had a marble that we dropped onto a piece of metal that guided the marble along until it hit a piece of duct tape, which stopped it until it started rolling the other way. It hit a square piece of glass that struck another marble so that it would roll down a piece of wood and roll down a corkscrew, made of the top of a soda bottle with duct tape inside. Then the marble would hit a line of dominoes, duct taped to a cardboard strip that was supported by a single dowel and hot glue. The dominoes knocked another, free, domino into a red solo cup that was supported by a string that also had a stick on the other end. This was a makeshift pulley, which pulled the stick up until it hit a piece of rotatable plastic that dumped a marble onto the hot wheels track and knocked a toy car into motion. The toy car hit a marble halfway down the track, and the marble rolled the rest of the way down the track until it sailed off the track, hitting another line of dominoes The issue with the hot wheels track was that we didn't bother to learn how to put it together, but rather hot glued and duct taped it in place. Also, we used flimsy cardboard to keep the marble on the track and to keep the track levitated, which all broke at the beginning of the exhibition. The dominoes in turn hit a piece of wood, attached to another piece of wood that pulled on a piece of wood under the large 2x6 and pulled it down. The 2x6 was tied by a weak thread that intentionally broke, pulling and releasing a metal chain that turned on a light. The complex part of making this Rube Goldberg was that we only had two people on our team, who both realized halfway through building the Rube that they didn't work together very well. Also, initially we thought that we had to pull and release the chain attached to the light, meaning that we had to make an object go down and then up again. We realize now that we should have used better materials, refined it better, and chosen different team members.
This project was, obviously, a colossal fail. This photo is from after the night of the exhibition. It only worked two days before the exhibition, and the night of the exhibition, broke and was completely unfix able. My teammate and I are considering redoing the project, if only to make ourselves feel better.
