Hamley Bridge Primary School
Hamley Bridge, South Australia
As an English writing task, each student
wrote a recount of our Waterwatch sampling day. From the students’ recounts the
class voted on one student’s work to be sent to the Bucket Buddies’ site. During
our sampling for macro-invertebrates our students worked in small groups. There
were a total of six groups. The results which are found in Samuel’s recount are
a total of the six groups.
Hamley Bridge is a small town, located in South Australia. We
are approximately 70 kilometres north of our state’s capital, being Adelaide.
Our town’s population is approximately 600. The rainfall is around 430
millimetres per annum. Hamley Bridge is located between two rivers. We take our
samples from the River Light, owing to ease of access for the students.
Currently we are in our Autumn season.
The Waterwatch program is a national program where people
sample their local waterway six times throughout the year. We test for: pH,
salinity, air and water temperature, turbidity, nitrate and phosphate. In
addition, during each sampling day we also sample and record the different
macro-invertebrates so as to obtain a pollution index and a taxa richness
calculation in order to see how healthy our river is.
Next term (three weeks time), as a class we will pose some
questions with regard to what types of macro-invertebrates other classes in the
Bucket Buddies’ program may have found. We will then look at the online data and
undertake the writing of a report.

The Waterwatch activities were fun because we got to wade
in the River Light.
Below are some photographs of the location where we undertake the sampling.
