Water Testing Connection

    Our group chose to focus on composting.  Our plan is to create a compost bin at school that people can throw there leftover food in after lunch.  Assentially there will be smaller bins in the lunch room, and at the end of the day we (Josie and I) could take them to the bigger compost bin that is outside somewhere around the school.  After a period of time the composst will turn to dirt that the school can use to plant flowers around the school.
   In our bio. bottle we will be testing a sunchip bag.  With our bio. bottles we will also be focusing on composting.  We will see how fast a sunchip bag breaks down compared to the other brush likes leaves and things that we use.  We will have one bio. bottle that will have just the already excisting dirt along with leaves and grass, and in the other bio. bottle will be the sunchip bag with the other leaves and brush.
   When we do the river testing tom. we will be testing for BOD (biological oxygen demand).  This relates to our action project dealing with composting, because when we compost we keep less waist from going into the river where we are testing the water.  The water will essentially be cleaner the more we compost.  Also the amount of oxygen could increase once we use the dirt from composting to plant more flowers and things, because they give off oxygen.
