MY CREEK JOB WAS TURBIDITY=http://
turbidity is the study of the cloudiness and clearness of water.we check for it because if the water is cloudy,it could be toxins,or acids floating in the water!!!The acids or toxins can effect the water by poisening fish and plants.if it is dead plants in the water,it can block the sunlight from coming in then it would make the living plants sick...we used this little machine and you get a small glass bottle of the creek water (or any water) and you put it in.you hook it up to a labquest and then it will show you the level of cloudiness in the water sample.!!! will finish later!!!!

Acidic and basic are two extremes thatdescribe chemicals, just like hot and cold are two extremes that describe temperature. Mixing acids and bases can cancel out their extreme effects; much like mixing hot and cold water can even out the water temperature. A substance that is neither acidic nor basic is neutral.
The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic. Each whole pH value below 7 is ten times more acidic than the next higher value. For example, a pH of 4 is ten times more acidic than a pH of 5 and 100 times (10 times 10) more acidic than a pH of 6. The same holds true for pH values above 7, each of which is ten times more alkaline—another way to say basic—than the next lower whole value. For example, a pH of 10 is ten times more alkaline than a pH of 9.
