What Do You Sound Like Science Fair Projects

Maturity science fair projects evaluate phsyical changes in voice box structure over time...

Pitch of Your Voice

The pitch of your voice does change as you age. Generally your voice is a higher pitch when you are young and a lower pitch when you are older.

Objectives/Goals

The purpose of this experiment is to determine if there is a direct correlation between relative pitch and gender.

Methods/Materials

1. Gather the necessary materials.
2. Record notes F, A, and C along with "Mary Had a Little Lamb" on a recording machine.
3. Ask a teacher#s permission to use classroom students for experiment.
4. Explain the experiment procedure to the students participating.
5. Find a quiet place to perform experiment.
6. Record gender and age of student participating.
7. Have each student try to hit the notes played, noting details in logbook.
8. Have student sing "Mary Had a Little Lamb" noting whether or not pitch was achieved.

Results

Approximately 76% of the girls achieved relative pitch in the experiment, while only 40% of the boys were able to achieve relative pitch.

Conclusions/Discussion

The hypothesis was correct. More girls were able to achieve relative pitch as compared to the boys. A possible reason is that the boys were in a younger grade level so voice maturity has not yet been reached. Some students hummed rather than sung the song. Further study results are pending as additional experiments are being conducted. 3rd party contributor
