Dear Palkia

March 16, 2008

Today at UOI time we went to the science lab to explore what is physical and chemical change. The first time Mr.Perico put water to the big cylinder and brown sugar to the small cylinder he said we should put the brown sugar to the water then the water turns brown. Second, Mr.Perico carefully put some drops of hydrochloric acid to the cylinder and he puts a magnesium ribbon to the acid. The magnesium ribbon is starting to bubble and it is losing its color it is also starting to disappear it will take 3o minutes and that is only 10% of acid. After that acid project we went back to the class then Mr.Perico told us to make a venn diagram that shows the difference and the things related in physical and chemical changes. Second thing we did in class is Mr.Perico gave us papers for each group with each topic and we must put it in the right column is it physical or chemical changes so that is today so bye.
