Trip to our local stream

On Tuesday the 10th of March Frazer came to St pius the x so
we could go see if our local stream in glen innes is clean, clear,
and to see if there is excellent good fair or bad life at our stream.
When we got there we saw a statue,I think it was an entrance that
they used to use a long time ago. Anyway he showed us a magnifying
glass that detectives use when they are solving a mystery or a murder.
Then he showed us this tube with a magnet inside
it and there's another magnite,
so you can move the magnet in the tube and  look
through a hole a the bottom of the
tube and water from the stream there's water from the stream
so when you move, the magnite
you have to try to not lose sight of it. Then we lastly did an
experiment on our water
to see how much life/oxygen in our stream. There are about
seven small tubes that
start from light blue and go to dark blue. Our water stopped at I think number there
so it was a fair I wish it could be alot better. What I would do to
make our local stream
clean, clear and non polluted. Is by being a cleaner there or even work there.

Have you ever done an  experiment in your local stream and why?

What would you do to make sure that your local stream is healthy and has life in it.

Summary I would like two again one year later because I would like to see if there is a change of life.
