River Detectives present their data

We made our poster to show the site we
collect our water samples from.

This poster shows the macro invertebrates
that we found when we tested the water.

A very sensitive water bug we found was
the water scorpion.

Our poster is about the health of the
river and what can be done to improve it.

Presenting the first poster.

This first graph shows the salinity levels
throughout the year.

The second graph shows the turbidity levels
each month.

This graph shows the Ph levels
throughout the year.

Our graph shows the Phosphorus levels
throughout the year.

We are sharing our knowledge about
all these macro invertebrates.

This group is sharing the information we
found on water scorpions.

Our concluding poster tells what we
can do to improve the health of
our river.

Angela, Nicole and Cass were our visitors
from the Regional Waterwatch program.

Looking carefully at the data on the graphs.

Testing the water for this month.The first
test was for the turbidity.We were able to
pour lots of water in, right to the top,
then over! This is really good.

Here we are testing the Ph levels.
We put 15 drops of chemical into the
water and read the results on the card.

The last group are testing with the EC meter.

That you Nicole for visiting us throughout the
year and for coming today with Angela and
Cass to hear our presentations.

Project presentations

Today Maia presented her project
on the silver gull to MU7.
We loved your costume Maia,
you made a great silver gull!

Broadbeans

Many students are enjoying harvesting the
produce from their garden. Today Agatha
picked lots of broad beans. She ate some
raw and took the rest home.
