Criterion D: Reflecting on the Impacts of Science
Task Organizer for Grade 8
A.
State the specific problem or issue dealing with sound
How does music and sound affect people’s emotion
B.
Outline how science is applied and used to address the specific problem or issue
Songs can help you change how you perceive world, in a positive or a negative way. This issue “How music affects people’s emotion” is not scientifically approved. There are many opinions that musics arouse memories from the past and make people resemble them, but a man called Frank Zappa retorted “There are more love songs than anything else. If songs could make you do something we’d all love one another.” There are no specific scientific evidences that music can change people. They are experimented out and it is true that music affects people, but the reason is not to be found out yet. It is scientifically said that when the brain hears a slow-beated music, it tries to match the beat to the heart beat. So that is the reason why your heart beats rapidly when you hear a pop music.
C.
Describe the implications (result) of using science and its application in solving the specific problem or issue and how it relates to an interacting factor below
Now my issue is “How does music and sound affect people’s emotions
Music was first made to celebrate the successful hunts that nomads did. All of their music were fairly exciting, with fast beated tempo going on, exciting people. Music was there from the nomads until now. Music can excite you or depress you, but music is surely a medicine for some people. Happy music can change how one perceives, helping them to be more positive. This can also socially help people out, by encouraging them. I think that music is really made to arouse memories of the past, since the nomads did it to resemble the hunt, and celebrate it. moral ethical social economic political cultural Environmental

Analyse the implications (result) of using science and its application in solving the specific problem or issue by drawing a conclusion on how much it affected the chosen factor
However, there are very negative points on music around you. Noisy music can easily create noise pollution, damaging your ears and hurting you emotion.
Negative music can also make someone feel sad and gloomy. It can work the exact same way that a love song or a happy song can work on you. Negative songs can work exactly the same way. It can disturb your emotion, make you feel depressed, and their tempos are very weird, unpredictable. As I said, music affecting emotion isn’t scientifically approved. The neurons in your hippocampus (in your brain) controls over emotion, so there might be a relationship between music getting transferred in to the brain. There was once a patient who lost most of the auditory cortex to strokes. This usually causes deafness but luckily his auditory association cortex was saved from the injury, not making him a deaf. He was able to hear, but by losing most of the auditory cortex, he wasn’t able to understand speeches and music which had harmonic patterns. This shows that auditory cortexes transfer sound to the brain. My opinion is, that the auditory cortex transfers sound to the brain and the brain would go over it. Cerebral is the brain part that has primary auditory area, which hears the sound. Then the sound travels around the brain, reaching the hippocampus. Hippocampus also contains memory, which gives me more clue that music affects emotion. Many people said that music recalls the memories of before, and I think that hippocampus releases the memories and control over emotions.
P.S: I wasn’t able to find an actual website with these information, about how the sound gets transferred and all that, so I am not sure about whether it is correct or not. But logically by my researches on each brain parts and some parts, (I did a lot of research for each parts since they were not shown scientifically in a website) some of them matches up and it starts to make sense. I found out interesting facts during this, and I learned very much from it, matching up the things myself, not just getting this info from a website.(Although I wasn’t able to find it, there might be a website) This experience was very good for me.
Remember: All points have to be backed up by research and examples.
