How people produce sound

Guiding question: How do people produce sound?

Hypothesis: We learned that sound come from the part of the throat called the larynx. In the larynx are your vocal chords. Air from our lungs causes the chords to vibrate and make sounds. I think that sounds will very given the amount of air you have and the way you form mouth.

Materials:
Just the piece of paper we were given in class

Procedure: We have to read the words on the list we were given and determine weather we are stopping the breath when we say certain sounds or not. I will have a partner to determine weather or not we are cutting sounds off by observing the way my mouth moves.

Record:
B= stopped
F= open
K= stopped
P= stopped
S= open
D= stopped
V= open
G= stopped
Z= open
T= stopped

Conclusion: From this, we can conclude that the way you form your words will definitely effect the sound. We learned that the way you use your teeth, tong, and lips is going to change the sound you make. For example the letter S makes a sound when we use our teeth and lips. And the letter T makes a sound when we use our tongs.

Further Inquiry: I'm really looking forward to digging deeper into how we make sounds. I wonder what will happen when we try and talk with a limited amount of breath so that the vocal chords aren't getting as much air from the lungs. I also want to know how sound travels through the air and why it is easier for it to travel through solids. I look forward to investigating this unit.

What happens when we get laryngitis?
When your vocal chords get red and swollen, this is something called laryngitis. This illness can cause people to "loose their voice", or not be able to talk because their voice is so horse. In children, it is often brought on by too much shouting. Singers also are more prone to this because their vocal chords are used in many different ways.
