Science fair project

1. Science fair project By Keagan Felder

2. Big question • Will bottles with less water make a higher pitch sound • I think this because more air is in it

3. Hypothesis • I think bottles with less water will have a higher pitch sound • I guess this because of a project my sisters did

4. 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

5. materials • 5 cups the same • Water • food coloring • Wooden stick

6. 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

7. Variables • How much water is in each glass

9. 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.

10. Analysis of data

11. 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.
