On September 8th the students learnt about macroinvertebrates,
their importance in the food chain and how their existence helps
to determine the health of the river.
All the students were given a container full of river water, an
icecube tray, plastic spoons, a magnifying glass, a two way bug viewer
and some macrinvertebrate identification charts.
Their task was to find, identify and name as many bugs as possible. They also had to determine whether the bug was very sensitive, sensitive, tolerant or very tolerant.
We found a wide range of macroinvertebtrates out of all of the four groups, so we determined that our local river, the Campaspe River, is healthy.
There was lots of encitement and fun as we found an assortment of nymphs, bloodworms, water boatman, leeches, caddisflies and many more.
To finish our investigation we put some of the bugs under the digital microscope to look at them on the interactive whiteboard. Wow, they looked cool and we had a fabulous time.
