Okeover Stream Observation

On Tuesday Room 6, 7 and 18 went on an adventure over to the Okeover Stream that runs through Canterbury University. Our focus was to make close observations of the stream. We took notes, drew diagrams and labeled all of the things we could see and hear.

After our observation we came up with some wonderings and some interesting findings.
Our thinking:
Why are there no fish?
What affect will all the rubbish in the stream have on the water and the animals?
Where does the water come from?
Where does the water go?
Is there something wrong with the water that there are no fish?
How come some plants can survive under the water?
Is it freshwater or saltwater?
Was the pink plant coral?
What would the stream look like at night?
Do the fish/eels come out at night?

I wonder if you can help answer some of our wonderings or share your thinking with us?
