  1. SUISUN MARSH’S: pH scale

  2. How Can We Protect Our Environment? • We can protect our environment by not littering and not polluting our air or water. • Not only does the pH of a stream affect organisms living in the water, a changing pH in a stream can be an indicator of increasing pollution or some other environmental factor. • pH tells us the acid factor in water which can tell us if the water is safe to use.

  3. What is pH? • pH is the acidity of the water. • We saw if the Suisun Marsh had a healthy pH balance. • The normal ph balance for water is 8.0 • The water at the Suisun Marsh had a pH mostly around 7.75 so its pretty healthy.

  4. Water Science For Schools • pH can tell us how healthy our environment is just by showing us the acidity. • Even though you may not hear it as a big problem everyone is having conversations about pH is a big part of our lives. • As this diagram shows, pH ranges from 0 to 14, with 7 being neutral. pHs less than 7 are acidic while pHs greater than 7 are alkaline (basic). http://images.google.com/imgres?imgurl=http://www.epa.gov/acidrain/site_students/images/phscale.gif&i mgrefurl=http://www.epa.gov/acidrain/site_students/phscale.html&h=332&w=396&sz=30&tbnid=RZIs--052IcJ:&tbnh =100&tbnw=119&start=1&prev=/images%3Fq%3DpH%2Bscale%26hl%3Den%26lr%3D%26sa%3DN

  5. What Did We Learn? • The pH scale tells you the acidity of a liquid substance. • It can show you all liquids acidity numbering from milk to acid rain. • pH stands for the powerofHydrogen
