TURTLE

Posted by Emma Connell in STORY-001 on
I want a baby turtle. They're just so cute and cheap to get. I would probably get bored of the turtle fast though. Once animals get old I lose interest. It's awful of me and I feel bad, but it's just the way I'm programmed. I'm also programmed to constantly crave something sweet, but I never crave anything salty.

​Guitar

--How is it played? What does the person have to do to produce sound?

It is played by applying force to frets and strumming the strings.

--How do you change a note? (you might have to watch very carefully to see this)
You change a note by pressing different indiv. frets/ indiv. strings /fret/strings combinations (called chords).

--How is it shaped?
It is shaped like circles, and rectangles. 


--What does this make you think about how you can create and change sound?
I know I must alter each of the thickness of strings and also I must alter the tightness of the strings along the neck.


--What connections (if any) do you think you can draw between what you are observing and you might already know about waves?
I know that the sound waves travel into the hole of the guitar and travel outward.

Guitar:

As the strings are "plucked" it makes a sound. Also the person has to hold the strings that are located in front of the guitar as he/she plucks the strings at the end. By holding the strings at the front of the guitar, this produces different sound. Since the guitar has a lot of strings, they all have different sound to it. To change a note, the person has to move to the desired string at the front of the guitar and at the end. This change the note and the sound.

Acoustic Guitar

http://www.youtube.com/watch?v=JsD6uEZsIsU

Acoustic Guitars are played by strumming up and down various strings that produce different sounds. You change the notes by placing your other hand along the top of the string on the metal bars that are called frets. An Acoustic Guitar is shaped like a number eight that is hollow and only has one hole in it which is located at the bottom. When the strings are strummed the sound travels down them into the hollow eight shaped part and the sound bounces off the walls of it to produce a much better sound. Above the base of it there is a long bar like object which has all of the string attached to it and runs all the way from the top to the bottom of the number eight shaped base. This makes me think that I would need something that is very good acoustics and is able to let sound move freely in it. A connection that can be made with what I already know about waves is that as the sound bounces off the inside of the guitar the sounds waves slowly dissipate jus as the energy from the slinky did.

For this project I have decided to make a violin. A violin is played by using your left hand to play on the strings and your right to move the bow to make the tune warmer. When you push down on a note with your left hand and move the bow with your right, you have to create an even tone and make it nice but take your time.
When playing the violin you change a note by putting you fingers on the string and moving the bow and the different strings you touch the different sounds come out.
The violin is shaped like a guitar it's just that the violin is smaller and doesn't have a hole in the middle instead it has a sort of lift in the middle where the hole would be.

Musical Instrument Blog #1 - The Flute

Posted by Chelsea Starks in PHYS-004 on


The flute has been a very intriguing instrument to me from the way it is held, to the way it is played. I have had the great opportunity of playing one and it's fairly easy once you get the hang of it. The flute is played by holding the flute to your right. Then by placing the lip plate just at the bottom of your lower lip, purse your lips together and blow as if you were saying the word "too." It takes a little while to get it but once you get the hang of it you're good. Changing notes is easy once you know how to produce sound. You have to hold down certain keys on the flute to make different notes and switch your fingers up and down and sometimes, right to left. The flute is shaped like a long rod with silver keys and is sectioned off by three pieces when disassembled. This makes me think about how easy it can be to change sound kind of like by allowing air to pass through certain holes in an instrument can effect the type of notes it plays. The connection I can make between what I am observing and what I already know about sound waves is that certain notes are louder and have a higher frequency reach people's ears faster than lower notes.

Here's a video of how to play the flute =)

Here's a video of some one playing the flute =)

Not sure if these can be viewed in school but give it a try!

When I was walking through the city the other day, I dropped an empty bottle I was holding onto the ground and it rolled under a street pole cover-thing. I looked to the left, and then I looked to the right, and then I walked away. True story.

Gay is the New Black?- Blog Post 2

Posted by Lexus Forman in ENG1-002 on
Gay is not a civil right? I don't understand, I think it should be because you should have any and every right to be happy in your own skin without feel any way about it. The definition of civil rights is rights to personal liberty established by the 13th and 14th Amendments to the U.S. constitution and certain Congressional acts, especially as applied to an individual or a minority group; the rights to full legal, social, and economic equality extended to blacks. As I research more and more about civil rights I find that people are blaming the president of the United States of America, Barack Obama for this non-sense. Msnbc.com are saying that when Barack Obama got elected in 2008, that is when voters in California voted to over turn the rights for gays and lesbians to get married in Florida and California. Msnbc.com asks “how can you compare being black to being gay?” You can easily hide the physical appearance of being gay to dodge the harmful discrimination by other people. However, you can’t disguise the color of black skin. There is not a way to escape the mind corrupting discrimination and non-acceptance.

Playing the Drums

Posted by Robert Broadwater in PHYS-004 on
I participated in a drum circle over the weekend and thought to make my analysis on all the different drums that were present. Some were hand drums and others had sticks and other tools for striking the head of the drum.

A drum is played by striking the head of it with either one's hand, stick or other relatively hard object. On some drums its impossible to change the note however on others, specifically hand drums, the player can place their hand on the open end to distort the waves on the inside and increasing the pitch. Hitting the drum at different distances from the center to the rim also changes the pitch, the center being the lowest and the rim being the highest.

Different drums are shaped differently and thus have different sounds, however the basic design is a cylinder open on one end and covered with an elastic material covering the other. Some drums have strings attached to the elastic head, that when tightened increase the pitch of the sound produced.

While observing and experimenting with all the pitches I was able to make with the drum, I noticed it was similar to the slinky lab we did on Friday. When the drum head was pulled tighter by the strings attached to the side there was less space for the same amount of energy to travel. Similar to the slinky when it was pulled for a long distance and shook the waves seemed long and slow, however when the distance between start to finish was shortened the waves shortened and seemed faster.
