Testing Omaru Creek for colour

Testing Omaru Creek for Colour

I am going to find out: How clean/dirty the water around G.I is

I am going to test this by: Putting the water into jar’s to see how clean/dirty the water is

Resources and equipment: 4 samples of the water around Omaru creek and the sea and the tap water

Results of my tests

Sea Water	Clean, but cloudy
Tap water	transparent and clean
Omaru Creek water by culvert	Green and dark pieces
Omaru Creek water by bridge	light green

My conclusion (what I found out): sea water is almost transparent

Why I think this is: Because lot’s of plants/fish clean the water

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.

Omaru Creek water by culvert	Musty and old
Omaru Creek water by bridge	old plants

My conclusion (what I found out): The culvert water was cleaner today than yesterday
