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.

Systems In a Human Body Info Paper 10/15/15

Friday and Monday we were writing down the definitions of (I believe) organelles that are part of the urinary and digestive system. Here are some examples of some of the organs my class had to write down the definitions for, the esophagus, the pancreas, the liver, the small intestine, and the large intestine. One thing that I forgot to add is that there was one other paper that had the definitions down for my class because I did not want anybody thinking that my teacher would make us write the definitions on our own out of the blue. The way we knew the definitions was because on Thursday or Friday I forgot which day any ways my teacher showed what every organ that we had to write the definition for what each organ did in order. But the fun part was she assigned every single person in my science class an organ to make it fun. What also helped was that Ms. J went over the answers with my science class also she allowed us to switch our answers if we got them wrong that especially helped

Chemistry Mastery Quest 2 Regrade

The Question I got Wrong Was: Reactions that involve burning are classified as I originally answered decomposition, the correct answer was actually exothermic. I realize now that exothermic is the better answer and was the correct answer. This is because exothermic reactions release heat causing its environment to get warmer. This creates a rise in the temperature which creates the burn. This means that exothermic reactions involve burning. This is why the correct answer was better than my original answer and is the best answer.

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
