Musical Instruments and Sound- Weekly Blog (3/11-3/15)

Sound Energy - Musical Instruments by SolPass

Summary

We understand how sound is produced, and how sound waves can travel through different mediums, but how do musical instruments produce sound? There are hundreds of instruments in the world, producing various pitches, tones, and chords. There are three main types of instruments: wind, percussion, and string. The sound is produced differently based on the type of instrument.

The first type of instrument is a string instrument. In a string instrument, the sound is created from the vibration of strings. For example, when you play guitar, you pull on the strings. As the strings vibrate, the air molecules start vibrating as well, producing sound. The next type of instruments are wind and brass instruments and are made when we blow sound into them. The shape and position of the instrument affect the overall tone and pitch. The most common kind of wind instrument is a reed instrument. Blowing on the reed causes it to vibrate, making a sound. The last main kind of musical instrument is a percussion instrument. In percussion instruments, the sound is created from a hitting motion. For example, you may hit a xylophone to produce sound.

SP2: Developing and Using Models

This week, we developed and used models to demonstrate how sound is created through a musical instrument. We started by drawing a sketch of our idea and the materials that we would use to create it. Next, we started building our prototype and made necessary adjustments. We used models to explain and predict behaviors of sound systems and how the structure of the instrument affects the sound. Using models has helped me learn more about musical instruments and how they can be used to produce sound.

XCC: Structure and Function

In class, I observed a structure and function relationship between the shape of musical instruments and the sound they produce. For example, the size and shape of a musical instrument is the structure. This affects the function of the instrument and produces a sound. The instrument's pitch and tone depend on the structure. However, the structure of the instrument limits the function and how many pitches it can play. Learning about structure and function relationships has helped me learn more about how musical instruments produce sound.

    Thank you for sharing such a relevant and practical post for the student community. Writing comprehensive research papers requires hours of dedication, which many students simply cannot afford due to tight schedules. When deadlines approach rapidly, finding specialized assistance becomes necessary. Looking for dedicated assignment help in melbourne gives students access to subject-matter experts who understand how to structure high-distinction papers. It is a highly effective way to alleviate academic anxiety and ensure that every submission meets rigorous institutional standards.

Structure of the Periodic Table - 9/25-9/29

https://image.slidesharecdn.com/theperiodictable-110223090122-phpapp01/95/the-periodic-table-7-728.jpg?cb=1298451775 Summary: This week, we have been learning about how the periodic table is arranged and the different patterns that are in the rows  and columns. In the periodic table, the rows are called periods. Along the rows, the elements are organized by atomic number (the number of protons.) The rows also have the same energy level or the number of electrons. For example, in the first row, all of the elements' atoms have one energy level, and so on.The atomic mass is the number of neutrons plus the number of protons. The atomic mass can be a decimal, and it is ordered increasingly. The columns in the periodic table are called groups or families. Each family has a name. For example, group one is composed of alkali metals which is the family with Lithium, Sodium, and more. Each group also has the same number of outer, or valence electrons. The elements in group one ...

The Carbon Cycle (3/20-3/24)

https://d32ogoqmya1dw8.cloudfront.net/images/eslabs/carbon/global_carbon_cycle_1427132279_456.jpg Summary: This week, we learned about the carbon cycle. The carbon cycle is a process that carbon travels in. There are six reservoirs or places that carbon travels in. G reenhouse gasses like carbon dioxide are dangerous because they are in our atmosphere and are causing the planet to become warmer. In other words, greenhouse gasses create an extra layer (like a blanket) in the atmosphere. This is because humans have burned so much fuel that there is about 30% more carbon dioxide than there was about 150 years ago. On the other hand, without greenhouse gasses, the Earth would be a frozen world. The six reservoirs are soil, the atmosphere, surface water, deep ocean, marine life, and land plants. 5,000 megatons of carbon are released into the atmosphere as fossils fuels are burned each year. When carbon is in the atmosphere, it is added with two oxygen atoms and becomes ...
