=Topic:__The amount of acids in sodas__= == =﻿I Problem:Are all soda equally acidic?=

=﻿II Materials:10cans of soda,research in labotory,14 bowls,google research,table of resolution for data,paper,science notebook= =V Data:=

=﻿III. Procedure:= =I went to google to get an idea of what i am going to do.= =I went to the store to buy 10 different kinds of soda.= =I return home and put them outside the refregerator so the amount of acids would be easier to be measured.= =There's a long-time friend of my dad who allowed me to do the experiment in his labotory.= =I collected the result of each soda.= =The next day i went to google and found tables that had the same results of the amount of acids and other beverages as mine so i pasted them on my page for more explanations of the data.=

=﻿IV. Hypothesis:I beleive that some of them but not all of them can be equally acidic because they don't taste the same. Eventors mix different ingredients to produce their drinks(sodas).The acid content of many foods and beverages may contributes significantly to their taste.=

=﻿VI. Conclusion:Not all soda are equally acidic but the amount of acids is between 2.50 and 4.70.The lower the amount of acid in a soda is, the healthier and less tasty it is.The highest the amount of acids is, the less healthy and the tastier it is.Acids can be classified as monoprotic, diprotic, triprotic, etc...Diet Barks(4.6acids,not that healthy) has the most acids but pepsi(2.49acids,acceptable) has the least acids.=

=﻿Journal #1 Date:March 28th,i got a not so good idea about the science fair= =﻿Journal #2 Date: March29th,i go to school scared by mrs kots speech witch motivate me= =﻿Journal #3 Date:March 30th,i quicly get to work and try to do something better and different to ameliorate my sciencefair.I hope it's good!!!= =﻿Journal #4 Date:April 1,now i can breath=

=﻿Journal #5 Date:Thank you Lord. Mrs kots,you are the best science teacher ever!!THANK YOU!!!!=
