Sound Waves Lab

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

Hypothesis: I think that the more smaller tune fork the louder the sound will be and the pitch will be higher.

Materials:

• tuning fork
• white board
• wood desk
• locker

Procedure:

Data:

	Description of the loudness of the sound	Description of how long  the sound lasts
Locker	The sound is high because the Layer of the locker is a thin layer.	the sound travels 6 second until it ends.
Wood Desk	The sound is very low because the desk is very hard	the sound travels 3 second until it ends.
White Board	The sound is very high because there is more surface area.	the sound travels 7 second until it ends.

III.  Exploration (PLAN & DO A TEST):
       Using the tune fork you are going to hit a table or something that is solid when you hit the table and place the tuning fork on the white board and see how the tune fork behaves.

IV.  RECORD & ANALYZE)

       

         C.  Analysis of Data: As i hit the thing on the desk there is a lot of vibration is small and as i place the tune fork i place on the board the vibration is bigger and bigger.


IV.(CONCLUSION): In conclusion this lab hes learned me a lot more about i wanted to learn i made me understand sound differently and how it behaves. I think that this is fun do do because you don’t have to researcher a lot you just have to do with the tune fork


V. (FURTHER INQUIRY): I would like to have done more of this and researched more because i enjoyed doing this a recommend to everybody to try and do this.
