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.

Facts on the Suisun Marsh

• This contiguous, brackish water marsh is the
  largest remaining on the west coast of North
  America.
• It is a critical part of the San Francisco
  Bay-Delta estuary ecosystem.
• Made up of 116,000 acres, the Suisun Marsh
  includes 52,000 acres of managed wetlands, 27,700
  acres of upland grasses, 6,300 acres of tidal
  wetlands, and 30,000 acres of bays sloughs.
• The Suisun Marsh is a resting and feeding place
  to all sorts of wild life such as birds, rodents,
  and even some reptiles.

Common Water Measurements

• All around the world measurements of water are
  being made. Even the most simple measurements
  can change what people know about the whole
  environment.
• How a waters properties change is more important
  than one single measurement. For example, if you
  are surprised that a creek near your house has
  the pH of 5.5 that acidy might be normal for that
  water.

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.

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).

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 power of Hydrogen.
• We also learned that that the Suisun Marsh is the
  largest water marsh on the west coast of North
  America.

Final Data

Final Conclusion

• In conclusion the Suisun Marsh is healthy in pH
  because a normal acidity is around 8.0 and most
  water there was somewhere around 7.75.
