Three Questions 1/17/14

1. What tasks have you completed recently? 

Recently, I have done multiple mini labs in chemistry, studied for a huge muscle system test in anatomy, and learned new vocabulary in Spanish. The mini labs have been great eye openers, and I have learned a lot from them. In other news, I almost died after studying for the muscles test for hours, but it was totally worth it. (:


2. What have you learned recently?

Recently, I have learned about chemical reactions, chemical and physical properties, states of matter, muscle contractions, microscopic muscle anatomy, and much, much more. Everything I have learned relating to chemistry has only furthered my interest in the subject, and the same goes for anatomy.

3. What are you planning on doing next?

Next, I am planning to review all of the material I have learned recently to ensure that I retain it. Regarding my life outside of school, I plan on spending more time with friends and family.

Mini Lab 1/15/14

In class today, we did a mini lab involving three white powders. To the naked eye, there was little to no distinction between the substances, and we could not tell them apart. By adding three different liquids (iodine, water, and vinegar) to the powders, we were able to learn a bit more about their individual chemical and physical properties, in hopes of distinguishing the three. When we added iodine to cornstarch, the cornstarch was slightly absorbed by the iodine and the mix turned black. Our baking soda and iodine combination resulted in the absorption of iodine and the substance turned a yellow-orange color, or the color of iodine. The baking powder and iodine mix fizzed, dissolved, and turned black. Water produced the least reaction, it only fizzed and bubbled when combined with baking powder, but when mixed with cornstarch and baking soda, the concoction simply dissolved. Last but not least, we experimented with vinegar. When combined with cornstarch, the vinegar was simply absorbed. That was not the case with baking soda and baking powder. Both fizzed and dissolved, with the baking soda dissolving quickly and completely, and the baking powder dissolving only somewhat.

Before this lab, I would have been unable to identify one of these powders if it was unknown, but now I understand how to distinguish between them. If I was given one of these powders as an unknown, I could identify it by testing it with different liquids. Now that I know which combinations cause what reactions, and by observing the chemical and physical properties of these reactions, I could tell them apart. Each reaction is different, making these powders relatively easy to identify.

My Passion

For as long as I can remember, and throughout my whole life, my passion has been gymnastics. Growing up, I did not mind spending twenty four hours out of my week in the gym, even though I missed out on social activities and some of the simple pleasures of daily life. I was so enthralled with the sport that I did not realize what I was missing. In foresight, I might have done things differently, or pursued one of my other passions such as horseback riding or soccer. This being said, my overall experience with gymnastics was positive. I learned who I was, who I wanted to be, and how to treat other people. Gymnastics taught me perseverance, hard work, and confidence. It also taught me how to put my faith in someone, because when a coach is spotting you on a skill that could literally kill you, you have to place your trust in them wholeheartedly. All of these reasons aside, the main source of my passion for the sport  stemmed from the level of difficulty. Whenever you mastered a skill, there was always another, even more difficult one waiting just around the corner. In addition, I loved the fact that I could do things the average person could not do. How many people can flip through the air at any given place and time? Not very many, that’s for sure. For all of these reasons and more, gymnastics is, and always will be, my passion.

Bouncy Ball Lab

In our bouncy ball lab, the main objective was to make a ball with the most bounce by finding the best combination of ingredients. In my partner and I’s experience, the property that determines a “good” bouncy ball are the proportions of ingredients; the proportion of sodium borate, water, and glue. Depending on the ratio of these ingredients, the ball can be too sticky, too misshapen, or it can be perfectly round and solid. We found that the best proportion of ingredients was a combination of 10 grams of sodium borate to 100 ml of water, and a proportion of .5 ml of sodium borate solution to five grams of glue. The proportions of sodium borate and glue matter because they influence the level of polymerization, therefore impacting the shape, texture, and density of the bouncy ball. We determined the best proportions through trial and error. We changed one variable at a time, so that we could understand whether the change in proportions was helpful or detrimental to the creation of a successful bouncy ball. Other than that, we simply made an educated guess depending on the outcome of our experiment, and then went from there, trying a different ratio in hopes of making a ball with more bounce. Our method matters because it is important to only change one variable at a time so that you can tell how the change impacts the consistency of the bouncy ball, and then decide whether the change was positive, negative, somewhat helpful, or completely ineffective, and so on and so forth.

Three Questions 1/10/14

1. What tasks have you completed recently?

Recently, I have completed many tasks regarding the start of the spring semester. I have finished any winter break homework, gotten together all of my school supplies, and done some necessary winter clothes shopping (a.k.a. sweats for lazy days). In terms of my personal life, I have focused on finding new hobbies and sports that I can enjoy either competitively or in  my free time. Also, I have spent a lot of time with family, and caught up on a couple of intriguing books I have been reading about pandemics and the psychology behind psychopaths and what the average person can learn from them.

This is an image of the cover of one of the books I have been reading. http://www.forbes.com/sites/kareanderson/2012/09/11/what-vulnerability-looks-like-to-psychopaths-monks-and-the-rest-of-us/
2. What have you learned recently?

Recently, I have learned that I am a much more fun and enjoyable person to be around when I am not super stressed. For this reason, I quit speech and debate club so that I will have more time to dedicate to homework, guitar lessons, and my personal life. Regarding school, I have learned that the muscle system is very complicated! I have been working on memorizing a portion of the muscles and comprehending the process of a muscle contraction.

3. What are you planning on doing next?

Next, I am planning on reinventing my life so that I can be  happier and healthier. I plan to do this through fun hobbies, exercise, spending more time with friends, and not sweating the small stuff. When it comes to school, I am planning on enjoying my classes, and keeping up with them so that I don’t get stressed when quizzes or tests come up.
