The things I learned in Science class were very interactive and uncountable. I learned an array of calculations, graphing methods, analyzing data, creating lab reports and doing experiments and the laboratory, while wearing lab coats and protective gears. Firstly, I learned are mostly about stoichiometry and the calculation that are involved in it to determine the molarity, mole, volume, particles/molecules and volume of a solution. At the beginning the symbols, notation and formulas seemed alien-like, but as time went by I understood and even mastered the calculations on top of my head. Secondly, I learned to create lab reports which were based on observations and its results that I got on a particular objective/hypothesis. Thirdly, I learned how to conduct a proper lab experiment and the aspects of being successful in achieving the endpoint (titration point) in solutions. This is my best sample so far in the history of my entire academic years in MYP since this is the first time I am getting a perfect score for a chemistry test. Usually since chemistry involves a lot of complex calculations, I often get mixed up and get stuck. This time everything went perfect and I earned a high score. I was able to achieve this score because of my perseverance and devotion when studying for the test. I didn't only used the provided notes, reviews and handouts given to prepare for the test but also watched educational Youtube videos on problems I didn't understand and comprehend about the notes/reviews that I did. The things/aspect that I could improve and do differently is to remember to draw a table before graphing. This comment given by my science teacher was extremely helpful as it helped me realize that small and minor mistakes can affect big portions. I learned that we must take every single aspect/method into consideration, and not just skip it (unless you have absolutely no time at all!). I have developed my understanding on the key concept of Systems for this subject. According to the International Baccalaureate, systems are set of interacting or interdependent components. I have developed in this area since I have almost fully understood the more about the system of stoichiometry and its functions.
