Guiding question:
How does density of various solids affect the was sound waves travel from the tuning fork?

Hypothesis:
I think that the denser the material is the louder it will sound.

Data Analysis:

Material	Density	Observation
Locker	7.85 g/cm 3	Tuning Fork 480 B: Very high pitched, proves that that the smaller they are the louder they sound. sound lasts for 17.69 seconds. a lot less vibration than with the larger one. Tuning Fork 256 C: lower pitched, sound is slightly harder to hear (not as loud) sound lasts for 15.03 seconds. a lot more vibration with this one than with the smaller one.
Whiteboard	2.8 g/cm 3	Tuning Fork 480 B: less vibration lasts for only 9 seconds. Tuning Fork 256 C: loud! not as much vibration as with lockers. sound lasts for 18.65 seconds.
Desk	0.75 g/cm 3	Tuning Fork 480 B: Just as loud as it was against the locker, sound lasts for, 12.35 seconds. Tuning Fork 256 C: Sound lasts for 30.73 seconds, More vibration than on white board and lasts for longer.
Wall	3.12 g/cm 3	Tuning Fork 480 B: Lasts for 20.75 seconds, more vibration than other ones. lasts longer than dest Tuning Fork 256 C: Sound lasts for 34.0 seconds, not very high vibration.
Wooden Floor	0.50 g/cm 3	Tuning Fork 480 B: last for 9.44 seconds, same vibration amount as locker, very hollow sounding. Pitch lower Tuning Fork 256 C: Lasted 30.43 seconds, vibration not very high, pitch was high sounding.
Cement Floor	3.12 g/cm 3	Fork 480 B: Lasts for 7.05 seconds, vibration high, pitch higher than mlst tries. Very loud, loudest one. Tuning Fork 256 C: Sound lasts for 27.25 seconds, vibration very high, higher than usually but not as high as last try.

Conclusion

The hypothesis turned out to be partially correct because we received the best results from the locker. We found that the larger the tuning fork was the lower the pitch was, and the smaller the tuning fork the higher the pitch was. I think that one of the reasons we got the best results from the locker is because the material of the locker and how dense it was. The material helped because out of all the materials we used it was easiest to move and vibrate in a way. And it was the most dense material that we used as well.


Further Inquiry:
We could have tested more materials, or the same materials with a bunch of different tuning forks. And then seen and recorded how they reacted therefore getting a better picture of the way the sound waves react when it comes to a variety of everyday materials.
