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
Tap water
Omaru Creek water by culvert
Omaru Creek water by bridge

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
