Turbidity in Omaru Creek

Testing Omaru Creek for -turbidity

I am going to find out: how clear the water is.


I am going to test this by: getting 4 samples from the creek


Resources and equipment: 4 samples from the creek and a peice of paper with small writing, nomal writing and big writing.also a bucket and a string.  


I predict that: the bridge will be the most cloudy


I think this because: the catfish are in the big pond bit


Results of my tests

Sea Water
9
Tap water
12
Omaru Creek water by culvert
14
Omaru Creek water by bridge
24


My conclusion (what I found out):brigde is the dirtrties out of all of them.



Why I think this is: because the catfish are going under the mud and making it all mucky
