Omaru Creek Testing!

Over the past days , my literacy class has been investigating the streams, Pond and colvert and we hae found out so many things!

Testing Omaru Creek for -

I am going to find out:  The turbidity of the water also what are differences between the colour.

I am going to test this by: By dipping a plain white sheet into the water to try and see the differences between the colour. I am also going to test the turbidity by putting the water into the jar and try and focusing on the water.

Resources and equipment: four Jars & a Bucket & a 4  White clean sheets.

Smell:

I predict that: That  the sea water would be the most “turbid” because you can hardly see the salt!

I think this because:

	Prediction	Observation
Sea water	Smelly, Salty & most of all .... Dead fish.	Salty , Fishes, Clay & Sand!
Tap water	Fresh & Clear!	Fresh & clear also like a clean stream.
Omaru Creek water by culvert	Yucky & would smell like Gas!	Gas, Oxygen weed and garbage.
Omaru Creek water by bridge	Oxygen weed , catfishes & tadpoles.	Oxygen weed, catfishes and tadpoles, also  rotten plants.

My conclusion (what I found out): Investigating the smell I found out that  “ducks eat the oxygen weed all though it still smells like it!

Colour:

I predict that: The colvert water would

I think this because:

	Prediction	Observation
Sea water	clear and see through!	Clear but a  tint of murky grey!
Tap water	Clean ,Clear & reflecting!	Reflecting & cLEAR
Omaru Creek water by culvert	Black and Grey!	Murky grey and green!
Omaru Creek water by bridge	MUrky and a tint of green!	Pale lemonade and tint of grey.

My conclusion (what I found out):I found out that each day the water changes!

Turbidity:

	Prediction	Observation
Sea water	I thought it was grey	It was actually clear!
Tap water	I think it goign to be clen	acutally it was CLean and clear
Omaru Creek water by culvert	Foggy and a tint of murky grey!	In reality it was “clear:”
Omaru Creek water by bridge	I thought it was velvet green.	It turned out to be really blurry!

My conclusion (what I found out): I found out that sometimes the turbidity changes.
