Sixth graders have been collecting water data both virtually
and in real time as they compare the pond populations in EcoMUVE to specimens
found in the outdoor classroom.
One of the most serious causes of poor water quality in our
county is eutrophication. This is when nutrients flow into the water with
sediment and cause algae growth. Bacteria
feed on the algae when it dies and deplete the water of oxygen. Fish kills occur because of the lack of
oxygen.
Students are working
in small groups and using the data they have collected to create and analyze
graphs that support the theories they have developed on why the fish are
declining in population.
The theories are not the same, but a lot of scientific
reasoning is taking place while students try to prove their theory to their
friends.
