Physical Science is indeed a broad branch of science. It consists of five sub branches namely Chemistry, Physics, Astrology, Earth Science and Geology. It demands critical analytic mind and also a patience attitude. Choosing to become a physical science student does not mean always to be dependent to the term called “luck”.

We wanted to extend our sincerest gratitude to the people guiding us along the way. Our teachers, who devoted a lot to make us understand the things that we need to understand, who are there to answer our questions formulated at the middle of the discussion with further explanation, who stand as our second parents in school for they don’t only provide us the intellectual knowledge but also ready to lend their shoulder for us to cry on. Our parents, who are there always to support us and primary source of our financial needs, who are always ready to hear our sentiments about the struggles we encounter in the learning process and who are there to push us to pursue our dream. Our friends, who act more than a siblings that always there to cheer you up when things gone wrong, who show their wit just to make you feel they are always around. Our special partners, who are always there both in sad and happy times, who kept on reminding you of your dreams to be reached, who show untiring love despite of both struggles and blooming days, the prime reasons why you see things positively. God, who we admire the most, who given us the capacity to think and work, who are the source of our energy, whom we trust a lot both in times of troubles and success.

We, the second year student of physical science, who are again saying “thank you” for all of you who are there to support us all along the way.
