The Theory of Discovery discussion and the documentary of the Samurai swords have a deep connection to our current studies to increase our technology and weaponry. These craftsmen and scientists create these remarkable things with materials, such as silk, the Thread of Discovery is a discovery that is biodegradable, edible, sustainable and can be implanted into the human body without causing any type of harm. It is also capable of the idea that matter such as a different state, can be changed. This new form has properties that make it very sought after by many people because it could be profitable, and it is renewable. The silk has created a way of thinking about holograms, reflectors and vein replacements as well as the invention of bones.The Samurai Sword is known also as katanas and is an ancient art that Japanese craftsmen would use. These Japanese craftsmen used their basic knowledge of elements and chemical/physical reactions to create one of the most amazing swords known to man. These swords could take months of physical labor and many people in order to create a sword that was made specifically for close combat. The sword could lead to other inventions if the two types of steel used to create the sword are transformed into other forms.This is a blade that has a hard outer layer that holds a very sharp edge that can easily cut a human in half, and had a tough inner core that could absorb the shock of impact to prevent shattering. The Samurai swords and the silk are both important inventions that have impacted our society with its mysterious qualities. They could lead to new inventions and have already led to other inventions such as airplanes and vehicles.
Today we performed our second mini-lab that consisted of testing three white powders: cornstarch, baking soda, and baking powder; mixed together each one with iodine, vinegar and water. These white powders can not be determined when being compared with each other by just looking at them. They can only be determined through physical and chemical reactions when combined with other substances. We began by adding a few drops of water to these three powders and the only one with a noticeable reaction was the baking powder as it started to fizz but did not dissolve well.The baking soda did not fizz like the baking powder and turned clear to where you could see the particles on the bottom. The cornstarch became milky and had a cloudy quality but separated to where the milky water sat on top and the cornstarch sunk to the bottom. When iodine was added to the powders, the baking soda again began to fizz and turned a dark brown/black color; the cornstarch also turned a black color but did not fizz. When the iodine was added to the baking soda there was a dramatic change in appearance because it was not the black color the cornstarch and baking soda had been but was a yellow color! Finally, drops of vinegar were added to the cornstarch, baking soda and baking powder. The baking powder fizzed when the vinegar was added yet it did not dissolve. The corn starch had no chemical change such as fizzing but the solution was a milky color and it did not mix well. The baking soda and the vinegar got very fizzy when mixed and was also a milky white but had a easily distinguishable chemical change. Now when given unidentifiable powders you can distinguish which powder is which due to their physical and chemical reactions to iodine, vinegar and water. Chemical reactions is the change that produces something new (composition changed), it can be identified by having gas produced, color changed, or producing a precipitate from solution only. Physical reactions are changes in appearance but not a change in composition; this can be identified by its change of state, change of shape and change of size. Each powder is unique in its specific reactions to specific chemicals and other substances, which you can determine through a series of tests and experiments.
When finding your own passion you have to ask yourself, “What work am I willing to suffer for today?” Great work requires suffering for something beyond yourself. It’s created when you bend your life around a mission and spend yourself on something you think is worthy of your best effort. My passion is cheerleading. I have been doing sports all my life, from gymnastics to soccer to swim, I’ve literally done it all because sports are a big part of my life. Cheer is very important to me because it is the one sport that I have ever wanted to do for the rest of my life, and cheer is the center of my life. Everything I do and every decision I make revolves around cheer and how it will effect my team. Every decision from my school work to who I hang out with and how I get a haircut is all about cheer. My social life is pushed aside, my free time is taken up and my heart, body and soul focuses only on cheer. It is the one thing in my life that has always been there for me and the one decision that I have never regretted. It comes with blood, sweat and tears but it all pays off in the end, all the hard work and time that I have put in this sport have been given freely by me. The gym has become my second home, my team is my second family and this sport is my passion.When you start doing something that you love and time seems to stop…You have found your passion. Go for it, live it, for that is the path you are meant to take. This path will lead you into wonderful new opportunities that you never felt were possible. Passions will emerge and we cram as much of it as we can into our lives, when you find your passion..you will find bliss.
In this lab we were attempting to combine sodium borate in water with polyvinyl acetate, also known as glue, to create bouncy balls. In order to make a “good” bouncy ball it must include these properties: round, smooth texture, to be able to hold its shape, and to have a high bounce. The proportions of your elements is crucial when trying to succeed in creating a bouncy ball that has all the mentioned properties of a good bouncy ball. The first bouncy ball my group created, we used 10 grams of glue and added 1 mL of the mixture of borax and water, this mixture had 75 mL of water to 10 grams of borax. This bouncy ball was a decent size that weighed 8.6 grams, it had a rough texture, but lost its shape pretty quickly and the size of the bounce was low to medium height. Our second bouncy ball, we used the same proportions as the first one but this bouncy ball weighed 9.2 grams, it had a silky texture, lost its shape not as quickly and had a low to medium bounce. The third bouncy ball we tried had 15 grams of glue and added 1 mL of the water/borax mixture. This resulted in the weight being 9.5 grams, lost its shape, was smooth texture and had a low bounce. Me and my partner went through these multiple tests because it was all about trial and error which we kept in mind as we went through our experiments. We started off with our proportions then changed one element at a time until we found a proportion that worked best. This proportion was 10 grams of glue with 1 mL of the water mixture to them, which resulted in one of our final bouncy balls as 8.2 grams that had a smooth texture, a low to medium bounce but kept its shape. Our second final bouncy ball weighed 8.1 grams, had a low to medium bounce and kept its shape with a rough texture. The element we kept the same was the borax solution and changed the amount of glue because if we were to change more than one element at a time, we wouldn’t know what made the difference in the end. Changing one element at a time allowed us to see how the different amounts of the ingredient affected the bouncy ball.These proportions and elements have to be controlled because it can affect the size, how well the bouncy ball holds it shape, texture and the height of the bounce
