Creating a Musical Instrument
By Jessica Tseng
Introduction: In this experiment, we attempt to make a musical instrument. My group decided to make a wind instrument, which is an instrument that requires a player to blow in it, in order to have sound. There are some examples of wind instrument like, trumpet, oboe, tuba, etc... In this experiment, we’re going to explain how our wind instrument was made, and how the instrument changes in frequency by blowing in it. For the materials, we used the straw to become our mouthpiece, and with a washing machine pipe to make the sound better, and to become the tube of our instrument. We will test different lengths of the instrument, and measure any difference in frequency, or pitch, between the lengths.

I predict that, if the length gets longer, then the sound will become lower. The reasons for that is because the frequency that vibrates in the air affect the pitch that the instrument made. The frequency of the air vibration depends on the length and the size of the tube. When the instrument gets bigger, then the sound will get deeper because when the instrument gets bigger, the length and the size will increase, and the air will vibrate in the tube longer, which is the wavelength. When the wavelength become longer, then the frequency will get lower, and also the pitch will gets lower too. There will be waves vibrating in the tube because when you blow it, you gave the energy to the tube, and the energy makes the vibration in the tube, finally, the sound will come out, and you will hear a pitch. This is a process of making a sound using a wind instrument. This experiment was similar to the last experiment, which is the sound experiment, last time I tested out a string instrument. In that experiment, we found out, when we press the string more shorter, then the frequency will become higher. Compare to this and the last experiment, it might had the similar result because most of the instruments use the same process to make sound, so the second thing I predict is that the result might be simillar with the last experiment because it both needs to increase or decrease the length of the
Does a father love his son? Josh wondered if his father loved him many days during his younger years, and love takes on a whole new meaning in Irene Hunt’s book No Promises in the Wind. The book starts out in Chicago in 1932 during the Great Depression period, times are tough as Josh’s father is without work and putting a simple meal on the table is a blessing. Josh also finds himself resenting his brother Joey because when he was born was when all happiness in the family ended, due to Joey’s many medical problems. This is one of the reasons that prompts Josh and his friend Howie to run away and find a better life, while Joey
The Native American flute is the third oldest known musical instrument in the world, with bone flutes dating back over 60,000 years. The first instrument found were drums, then varies whistle were made. Over time, the instrument evolved with many different materials and shapes. And these difference and changes reflect the culture of that time. Virtually, flutes were used all types of hardwoods and softwoods in history. They had many different configurations, 2, 3, 4,5,6,7 or 8 holes. The flute we used in class is 6 holes, and we also saw many different flutes in class, someone smaller, someone larger, someone with 3 holes, etc. The oldest flutes we have were made from wing bones of a Griffon Vulture [1] and a Whooper Swan [2], as well as one from mammoth tusk ivory [3].

The world can become a slippery slope discussing religion and science. Inherit the Wind takes on the task of showcasing the struggle between religion and evolution. The play places all attention on a trial about whether or not one should be allowed to teach the theory of evolution in the classroom when it goes against the Bible. The case allows for the audience to see the division, and bias, between those present in the court. Brady represents the religious advocate whom receives a warm welcome showing the favoritism of the Hillsboro people for him, and therefore the prosecution in the case. Meanwhile, Drummond the defense is depicted by the townspeople as a ‘devil’, and a source of evil. However, when the reporters and critics roll in from
Inherit The Wind is a story written by Jerome Lawrence along with Robert E. Lee. That fallows the story of a school teacher named Bertram Cate, who is being put on trial for teaching the theory of evolution to his students when it is considered illegal in Tennessee at the time. this leads to a long debate over people’s right to think what the bible states. Now this story containers many characters with very different personalities and traits. The character that connects with me the most is Henry Drummond, who is the attorney for Bert in the case.
The clarinet is a woodwind instrament consisting of a cylindrical wood, metal, or ebonite pipe with a bell-shaped opening at one end and a mouthpiece at the other end, to which a thin reed is attached. The clarinet has five different sections, the mouthpiece, the barrel, the upper section, the lower section, and the bell. The length of the entire instrument is 60 cm long. The mouthpiece section consists of a slotted cylinder, to which a reed is attached by a metal clamp called a ligature. The mouthpiece plugs into the next section which is a barrel. The barrel is simply a connecting cylinder to which the mouthpiece and the upper section plugs into. The upper section is a cylindrical pipe consisting of 4 holes and 9 keys placed in different locations along the pipe. On the back of the pipe there is a hole and a key that is used by the thumb. The lower section plugs into the upper section and is also connected via a special bridge key. This piece consists of 3 holes and 8 keys. On the inward facing side of the pipe, there is a protruding piece of metal called a thumb rest, which supports the entire clarinet. The bell plugs into the lower section. It consists of a cylinder that flares out into a bell shape and ends the clarinet.
Utah can have some serious winds. In 2015 there was a big windstorm that caused little damage in the Ogden area. It was caused by a strong wind sear.(natural history of Utah, by, Stefan Brems)
The vibration of the strings of a guitar causes the sound wave, but is not actually what you are hearing. The amplification of the sound wave is what is actually heard. The differences in the tension of the stings and the mass of the strings affect the pitch of the sound produced. The ends of each string are nodes, or where the wave does not travel from its initial position. The note you hear from the string is actually the first harmonic of the wave; other harmonics created when plucking a string form the undertones and overtones of a note. The waves on a guitar string are transverse waves, meaning they travel perpendicular to the original position. The waves are also standing waves, because they remain in the same position.
The scene that introduces the audience to Matthew Harrison Brady, in Inherit the Wind, (Dir. Stanley Kramer. With Spencer Tracy, Frederic March, and Gene Kelly. MGM. 1960) uses dialogue, composition, camera work and music to develop Matthew Brady. Kramer reveals important information about the plot of the film in this scene. The scene opens with a bird's eye view shot of the town of Hillsboro, and focuses in on the movement of the parade below. The camera comes to rest on the convertible that transports Brady and his wife. The town of Hillsboro welcomes the well-known politician. He will serve the town by being the prosecutor in a trial about evolution, similar to that of the historical Scopes Trial. This scene, where we first meet Brady, reveals his strong character, and the role of savior that the town expects him to play. Through the development of Brady, Kramer also introduces us to the issues of religion and politics. Stanley Kramer, the director, introduces the audience to two key ideas in the very first shot of the scene. He does this through the use of background tools, like music and scenery. As the camera fades in from the previous scene, music begins to play, and a group of women sing a religious hymn, "Give me that old time religion." The extremely loud music continues for the duration of the parade. At first the audience doesn't know the source of the music, but as the parade comes to an end, the camera focuses on a group of militant looking women, who march and sing. This song draws the audience into the impending controversy over religion. It expresses the entire town's point of view on the issue. The audience can see that religion affects the soc...
“The Boy Who Harnessed the Wind” is about this young boy named William. William and his family have dealt with a lot of heart and pain in their life. However, through all of what he and his family has been through, William has learned that you must believe in yourself, and have faith that you can accomplish all of your dreams, if you just put your mind to it. William was born and raised in Malawi, Africa. His father was a farmer just like every other man in Malawi. Since William’s father was a farmer and his mother works around the house, his family didn't have a lot of money. William was always excited about school. School was one of his most cherished places to go. He attended Wimbe Primary School, where one mid-September, they took their
In this essay about the book ‘The boy who harnessed the wind’ written by Bryan Mealer & William Kamkwamba I will firstly describe William Kamkwamba and his early life in Malawi. Next discuss the challenges he faced and how he was able to build a windmill.
Today’s report involves the history and the rumors surrounding one of the most intricate and potentially dangerous individuals to have access to our world, we speak, of course of Hasan Ibn Al-Haythum. Hasan is known for in the past as an Arab mathematician, astronomer, and physicists during what is known as the Islamic Golden Age. He is widely known as the first scientist, as he conducted the first experiment around the year 985 nd proved light was more than just a wave. What was left out of history was his secret desire for the dark arts, and everything that goes along with it. He, or better described now as it, is a being not of the life, not anymore, but a pseudo-puppet, moving through our world as if inspired by a silent wind, graceful yet curious. I believe this silent wind is some dark deity of great power, that not of human understanding. Some would describe him a simple merchant, others would give him the name, arms dealer, extortionist, fool, hoarder, the list of titles goes on for some time, but frankly not all words are not nearly enough to provide context. And the context surrounding Hasan, if it can even be called that, remains to be proven as factual evidence. We have pieces, no crumbs of information grounded in reality, but most of our knowledge
A wind turbine is a device that converts kinetic energy from the wind into electrical power. Small wind turbines we discussed for domestic use have fewer requirements to properties, but more considerations of cost compared to large wind turbine.
There are many different sources of energy that are naturally available throughout the world in different forms. There are two types of energy: renewable and non-renewable. Non-renewable is made from fossil fuels; which can include oil, coal and wood. They are non-renewable because they are not regenerated immediately, and it can take between 100-100,000 years to make a fossil fuel. They are important because they produce constant energy throughout the world. This is because of their high availability. The problem with non-renewable energy is that, when burned, they release harmful greenhouse gasses into the atmosphere. Especially when the world, as a whole, is using too much too quickly; and therefore the earth cannot replenish the fuels naturally or quickly enough. Renewable sources of energy are obtained from different natural sources. A benefit about this kind of energy is that it can be replaced and it is sustainable. Renewable energy is important because it is used significantly in electricity generation and heating. It is also important because it can be replenished, and therefore it is better for the environment.
...te. In old times, most flutes were made of bamboo, which allowed even common people to play it. By covering the holes and blowing through the side hole while moving the fingers flexibly between the six holes, a sound will be produced that is leisurely and mellifluous like sound from far away. This always reminds people of a pastoral picture of a farmer riding on a bull while playing a flute
