Science fair project
By Keagan Felder
Big question
• Will bottles with less water make a higher pitch sound
• I think this because more air is in it
Hypothesis
• I think bottles with less water will have a higher pitch sound
• I guess this because of a project my sisters did
Fun facts
• More water makes the pitch lower• If the bottles are not the same they have different
pitches• if you put the same amount of water in a glass the
pitch will be the same• If you have the same cups with 1 gram less water in
1 then the other it will have a higher pitch sound• If you test tubs the amount of water could be more
exact
materials
• 5 cups the same• Water • food coloring• Wooden stick
Step by step instructions • Buy 5 bottles• Buy food coloring • Fill each bottle with water• Get spoon or wooden stick• Use spoon or wooden stick to tap the glass• After you tap each glass make a graph to tell
how high the pitch is
data
• When there is more air allowed in something and you hit it has a higher pitch sound. When you have less air in something it has a lower pitch sound. Also that has to do with how much water or other liquid you put in it.
Analysis of data
• The one with less water made a higher pitch sound
Conclusion
• Yes my hypothesis was right. I would change the amounts of water I would do this to see if I got higher pitch sounds. I also would change the glasses I used. To see if that would make a difference. The new questions I have are if I used a different shape glass to see if the pitches were different pitch. What if I put the glasses with more water in front when I hit them all at once will it sound different.
