Turbidity(clear) the water from Omaru creek

Turbidity  Testing Omaru Creek for -

I am going to find out: The turbidity of the creek

I am going to test this by: sampling the water and putting something behind the glass jar and find out how clear you it is

Resources and equipment: 2 bucket, String, 4 glass jars and paper with writing on it big to small

I predict that: The size we see through the bridge water will be 12, the culvert 9 and the control waters 9 too.

I think this because: The bridge water looks green and cloudy.

Results of my tests

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

My conclusion (what I found out): The water by the culvert is has more turbidity than the bridge water

Why I think this is: Because the water coming out of the culvert is clean, I think that the catfish are

stirring the mud and rubbish up from the bottom of the creek.
