Making Music | 3/11/19-3/15/19

Summary:

       Music is created through the vibrations of molecules when sound waves hit them. In order to create different sounds and have a full scale, you must be hitting things with different measurements. For example, to test this, you can hold an object such as a ruler, and grab on to a part of it that is somewhat close to an edge. Then, hit the side of the ruler that is smallest, and then hit the other side of the ruler. You will then notice a difference. This is due to how the amount of space that the sound wave can travel is different when changing the size of the object in which you hit. This is the exact way that some instruments function. Instruments such as the xylophone or glass harp (the one where the cups are filled with water). For the xylophone, the bars (the things that you hit) are all different sizes. For the glass harp, each glass is filled with a different amount of water, which means that the sound waves have different amount of spaces to travel. This is how varying measurements creates different sounds. 

S&EP 5-Using Mathematics and Computational Thinking:

       I used mathematics and computational thinking this week when creating my musical instrument. As mentioned above, we (my group) found out that in order to play different sounds that have different pitches, you must have varying sizes of a certain material (at least for the instrument that we had in mind). So we used mathematics to plan out and eventually build our instrument. We had to come up with the smallest size for one of the things that we were going to hit, and the amount that we would increase from each thing. We wanted to ensure that you could hear a difference but that it gradually changed increments at a time. Because if not, we would end up having our biggest thing that we are going to hit be very large, which is the exact opposite of what we were going for. Our mathematics ended up working and our instrument was able to play a full scale. As we ended up having our smallest thing being 6.5 cm and each thing increased 1 centimeter from the previous

XCC-Systems and System Models:

       The system I identified this week was our musical instrument that we created. The parts of our system are the base PVC pipe, the sticks (the things that you hit), and the rice inside of the pipe. All of these parts work together to create sound and music. The base pipe is what holds the sticks and rice, and without it, none of our parts would be together. The sticks are what is majorly used to create sound. Each stick plays a vital role in creating a different pitch so that we can create music. All eight sticks are what is used to create a full scale. Lastly, the rice is what is used to create a totally different tone of sound so that the music stays nice and fresh. This rice is what will be used when needing to take break up the hitting of the sticks so that a completely new type of sound can be produced.

The Sulfur Cycle 1/20/18

Image
Summary:        This week in science we learned about biogeochemical cycles, more specifically, I learned about the biogeochemical cycle known as the Sulfur Cycle. What I now know about the Sulfur Cycle because of what I learned this week through research is each part in the sulfur cycle. I also now know that their are a lot of different parts in the sulfur, but my focus was trying to make this complicated cycle very simple and easy to understand. The first part in the Sulfur Cycle is  Hydrogen Sulfide Gas is released into the atmosphere by the eruptions of volcanoes, hot springs (“ spring produced by the emergence of geothermally heated groundwater that rises from the Earth's crust. ”) , and the decay of living biological sulfur-containing materials in swamps, bogs, and tidal flats. Sulfur is also released from the ocean in sulfur-containing compounds in sea spray, and as the gas hydrogen sulfide. I also know that most of the sulfur released from the world's oceans does so

Plate Tectonics 3/10/18

Summary:        This week in science we learned about Plate Tectonics. Plates have been on Earth for thousands of years and are consistently moving (very slowly). Through this the Earth can recycle our land, by destroying the old land, and creating new land. These plates are made of rock and are in the lithosphere layer of the Earth. Another thing I know is that there are 3 different type of plate boundaries. Those three types of plate boundaries are convergent boundaries, divergent boundaries, and transform boundaries. Convergent boundaries are when two plates collide and their are two different types of convergent boundaries. The two types of convergent boundaries are collisional boundaries and subduction zones. A collisional boundary is when two plates with the same density collide. Because they are the same density the plates buckle and warp. The land then pushes up into jagged peaks forming a mountain. Subduction zones are when one dense ocean plate converges with a lighter con

Analog Vs. Digital debate - WAC 3 Argument | Nicolas Reed-8th Grade Science

nreed1005 Ms. Garcia Science 8 4/5/19 Digital is Better than Analog        “There's an ongoing flood of new LP releases (Amazon currently lists 938,000 LP titles ). Kings of Leon, Taylor Swift, Nine Inch Nails, and Kanye West all have their latest releases available on LP.” according to the article titled, “Why does analog sound better than digital,” by Steve Guttenberg. Digital is better than analog. Digital allows you to have a clearer sound that is controllable and can last forever. Most importantly, it is cheaper, which means that it can used by almost anyone. Analog is the past, we must invest in the future and use digital.        Using digital means having high quality sound that can be manipulated. “Digital has certain perfect things about it [, it] immediately solved all the problems of analog background noise, hiss, where pitch control all of those things.” according to the video titled, “Analog or Digital? (1993),” from PastVid. Digital allows you to have “go
