The coluer of omaru creeck water

Testing Omaru Creek for -coluer

I am going to find out: what coulur the water is?

I am going to test this by: campairing diffrent water samples.  

Resources and equipment: the 4 samples of the sea water,the tap water,omaru creek bridge water,culvet water

I predict that: the seawater will have littel bits of salt init.

I think this because: the water is salty.

Results of my tests

Sea Water	clean and clear
Tap water	clear and vervy clean
culvet water	grouies
Omaru Creek water by bridge	dirtey and yuk

My conclusion (what I found out): that the bridge water is dirteyer than the culvet

Why I think this is: because pepole drop more rubbish near the bridge
