omaru creek testing

Testing Omaru Creek for -colour

I am going to find out:

what colour the water is

I am going to test this by:

comparing different water samples

the culvet

tap water

sea water

and the bridge

Resources and equipment:

4 water samples

the omaru creek culvert

omaru creek bridge

tap water

I predict that:

the omaru creek culvert water is dark green

tap water clear

omaru creek bridge is multicolour

sea clear

I think this because:

i think the sea water is clear because there’s a big space to spread

tap water is clean because there’s a cleaner to clean the tap water

omaru creek is dark green cause theres rubish

omaru creek culvet and it has rubish

Results of my tests

Sea Water	Cloudy
Tap water	Transparent
Omaru Creek water by culvert	Bits
Omaru Creek water by bridge	Light Green

My conclusion (what I found out):

The seawater is very clean from the mangroves and all of the space .  The culvert water is dirtier than the bridge water.

Why I think this is:

because the rubbish from the road go’s in the creek
