Today in class we checked our expirement on measuring water loss from leaves. We went outside and collected our baggies that we tied on trees and found that they had collected some water from the leaves. Then we weighed aour baggies and recordered our information. It was a really short class due to the terry fox run so we just worked on questions about acid deposition for the rest of class.
I was really surprised on how much water was actually collected in the baggies. Some people had 7 grams of water collected in one of their bags. It think it was a really good expiriment because it really shows the major role that trees play in tranpiration.
I did some googling on acid deposition (acid rain) and found out that acid rain is usually characterized as any precipitaion with a pH of 5.6 or lower and can be in any form of rain, snow, mist, dry dust, hail, or sleet. Also 10% of all sulfur dioxide emmision comes from volcanoes, sea spray, plankton, and rotting vegetation.
