Tunning Fork Lab

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

Hypothesis: If the material is very dense, then the tuning fork will travel faster.

Materials:
1. Tuning fork (the main material)
2. Table (for testing if the tuning fork vibrates)
3. Computer (Google Docs, for putting the data)
4. White board (Because it is plastic)
5. Wood
6. Metals
7. Watch stop

Procedure:
1. Take a pencil and a notebook before you get started with your experiment, because you wouldn’t want to miss something out, otherwise everything would be incorrect.
2. Take a tuning fork of normal size and hit it on each material. You should feel the vibration of the tuning fork while you’re holding it.
3. Get a timer/watch stop and time how long the tuning fork vibrates. Save your observations on a document or in your notebook.
4. Repeat the steps above.

We found different material to measure the sound of the tuning fork when it vibrates.
We tried it in different materials and we measured them as you can see in the table below.

Data Analysis:

Material	Observation
Metal (Locker)	Soft vibration
Wood (Table)	Very long vibration and on wood it lasts for a long time but soft
Plastic (White Board)	Loud but slow
Rock	Vibrates slow but is loud.

Conclusion:
Jovana’s Conclusion:
In conclusion,

Ergi’s Conclusion:
In conclusion, our hypothesize was right. If the material is denser the tuning fork will be slower. On the table above hard materials all ways lasts longer and has a heavier sound than the others.

Ergi’s Further Inquiry:
An interesting thing I learned was that on wood it makes a very long vibration and it lasts for a long time. But, the song is not that high.
