Testing Omaru Creek


Testing Omaru Creek


I am going to find out the differences in colour smell and turbidity of Omaru creek



I am going to test this by comparing different water  samples  from different locations along Omaru Creek.


Resources and equipment:
Buckets jars paper

Smell:


Prediction
Observation
Seawater
I think the water will be Salty
It smells like Bad fish (too me)
Tap water
I think the water will be Fresh clean water
It smells like Fresh clean water
Omaru Creek water by culvert
I think the water will be Oily  rubbish
It smelt like Dead fish (too me)
Omaru Creek water by bridge
I think the water will be Disgusting
It smelt nice (but when you shake it and smell it as soon as it opens)
Side of the lake
I think the water will be kind of fresh
It smelt like fish (to me)

My conclusion (what I found out): I found out that most of my predictions were very  close to my prediction.

Colour:



Prediction
Observation
Seawater
I think the water will be clearish
It looked clear
Tap water
I think the water will be clear

Omaru Creek water by culvert

It looked like there was heaps oily leafy heaps rubbish
Omaru Creek water by bridge

My conclusion (what I found out): That my predictions were not too far from the observation.


Turbidity:



Prediction

It was Totally see through
Tap water

My conclusion (what I found out):I found out that the water always  moves along the stream so the oil can get to the bridge.
