In this project, I use Vanillin as the compound I research for. I use scientific journals as my source of research. I researched about its chemical and physical properties, functional groups and applications. ESLOsI performed as strategic learner in this project. First, I use technology to learn, research, and work. all information in my report are come from my learning online, especially in sciencedirect.com. Second, I manage time well. Before i start to do report, I make a plan about it, and I followed it all through the project. Third, I didn't only make a plan about time, also a plans to learn. I set how many journals will I focus on, and how deep will I read in that journal.

Rocket project is a chemistry project, and need to be done by rocket which use baking soda and vinegar as fuel. The reason I choose this project to shown in here is this project is most challenging project through the whole year, and can provide enough evidence on my maximum chemistry ability. Informations: Baking is the limiting reagent. Vinegar is the excess reagent. Chemical formula are as followed: Vinegar (CH3COOH) 5% = 5 g of 100 ml H2O Mol= gramsmolar mass= 560.05=0.083 mol 100 ml of CH3COOH = 0.083 mol 350 ml of CH3COOH = 0.29 mol Baking soda (NaHCO3) Mol=gramsmolar mass= 2084.01=0.24 mol Baking soda is limiting reagent. CH3COOH+NaHCO3>CO2+ H2O+ CH3COONA (0.29 mol) (0.24 mol) (0.24 mol) CO2 mol = gramsmolar mass 0.24 = grams40.01 In this project, I performed well on being an innovative speaker, because I write and perform every step of this project based on calculations and plans, also most of these calculations are based on our knowledge that we studied in chemistry before.
