The water experience

My name is Jorge, I am 22 and I am doing the Environmental Chemistry course in the I.E.S. Concepción Arenal in Ferrol. Last week was unusual for the life in the high school, it was the Water Awareness Week and I was in charge of the explanation of some experiments that took place in the high school`s hall. It was such a good experience because we could get closer to the responsible of life in our planet, which is water. This little molecule is too unknown in common life and it has many properties that you can`t believe. This past week was really good to learn about this resource which is not as abundant as we can think; only the 3% of the total water in the planet is fresh water. I had to explain some properties such superficial tension of water and the Arquimedes principle, helped by funny and interesting experiments. I was very glad helping teachers this week.
