1Cold Water and Your Voice: How does the water affect your range? Ashley DobsonHyde8th Grade
2Topic Question:Does drinking cold water before singing effect how high a person can sing?
3Hypothesis: I think that if a person drinks cold water before singing, they will not be ableto sing as high as theycould without drinkingcold water because cold water has a numbingeffect on the throat that makes it more difficultfor the vocal part to work properly.
4AbstractIn this project, I determined whether cold water has a positive or negative effect on your vocal range.I hypothesized that if a person drinks cold water, they will not be able to sing as high as they could without drinking it.I tested this using four girls, all around the same weight and size. For each test, I had each girl sing a G scale. Then, they drank a cup of cold water (42 degrees Fahrenheit) and sang the scale again. I recorded whether they could sing higher before the water or after it.I concluded that cold water has a negative effect on your vocal range, making you not able to sing as high as you could without it.
5Materials: Four singers around the same age. (8-9) Four cups of the same amount of water and the same temperature. (42 degrees Fahrenheit)PianoWater thermometerMeasuring Cup
6Variables: Manipulated (Independent): Whether the singer drank cold water or no water.Responding (Dependent):How high each singer can sing on a G scale. (Do, Re, Me, Fa, So, La, Ti, Do)Controlled:The amount and temperature of the water.The scale each singer sings on.Whether the singer has drunken or eaten anything for thirty minutes before the experiment.The age of the singers. (8-9)
7Step-By-Step Procedures: Gather four singers (Dana, Anna Whatley, Olivia, and Claire) around the same age. (8-9)Make sure the singers haven’t drunken or eaten anything for at least thirty minutes before the experiment.Have one singer sing a G scale (Do, Re, Me, Fa, So, La, Ti, Do) along with the piano until they can’t sing any higher.Record how high the singer sung.Repeat this process with the other three singers.Fill a cup with ¼ cup of water, using a measuring cup.Make sure the water is 42 degrees Fahrenheit with the thermometer.
8Step-By-Step Procedures: (cont.) Have the first singerdrink the water.Immediately afterdrinking, have the singersing the G scale again(Do, Re, Me, Fa, So, La,Ti, Do) along with thepiano until they can’t sing any higher.Record how high the singer sung.Repeat this process with the other three singers.Determine whether each singer’s range was higher without drinking water or after drinking cold water.
9Data Singer: Dana Anna Whatley Olivia Claire Without Water Reached the end of G scale (Do)With Cold WaterReached “So” on the G scaleReached “Fa” on the G scale
10Note Singer’s Reached With and Without Water Key:Do-1Re-2Me-3Fa-4So-5La-6Ti-7Do-8Note Reached on G scaleSinger
11Results:I claim that drinking cold water made the singers not be able to sing as high as they could without drinking water.I claim this because before drinking water, each singer reached the end of the G scale, but after drinking cold water they weren’t able to reach the end.
12Conclusion:In this experiment I learned that drinking cold water before singing causes you to be unable to sing as high of notes as you can without drinking cold water. I know this because each singer in my experiment wasn’t able to reach the end of the G scale after drinking cold water, and before drinking water they were able to.My hypothesis was correct because I said that drinking cold water would make you not be able to sing as high, and that’s exactly what happened.
13Application This project can be applied to real life if you are a singer.Knowing how cold water effectsyour vocal range can helpsingers know what to drinkbefore a performance. Becausethe outcome was that cold water makes your vocal rangesmaller by numbing your throat, singers would know not todrink cold drinks before a performance. Instead, they coulddrink room temperature drinks. That way they can have anoverall better performance.
