Introduction

• Sound Waves

3
Problem

• How does the sound go through the yarn and into
  your ear?

4
Materials

• 36 inches ruler 1 yard
• Metal fork
• String yard 36 inches
• Cement wall

5
Hypothesis

• The conductor will send the vibrations along a
  string and enter into the eardrum.

6
Procedure

• Take a ruler and measure the yarns about 1 yard.
• Take the yarn and tie it to the middle of the
  metal fork.
• Wrap the fork around both of your pointing
  fingers.
• Put your fingers to your ears.
• Hit it against the desk

7
Data

• At first we tried to do our experiment with a
  plastic fork ,but it didnt work ,so we had to
  use a metal fork. From our understanding between
  the metal and plastic fork ,the metal fork work
  better. Since we are looking for sound waves ,the
  plastic fork didnt give us of an out come ,there
  was no vibration. The sound that went through the
  string, through the fork, and into the ears.
  Through our ears it seemed like the fork kept
  shaking and felt like a sonic boom go through our
  ears.

8
Results

• It goes through them by the vibration when it
  hits the hard object.

9
Conclusion

• Sound waves can travel along or through a string
  when you use metal as a conductor.
