Projects bound to impress
■ A Karratha student has incorporated fishing into her homework to create a Pilbara high school science project, which she hopes will win her a trip to China.
St Luke’s College student Maddy Wilson, 15, is one of nine Pilbara participants from Scitech’s Beijing Bound program.
The program is run with support from Rio Tinto, which provides some of its graduates to the students as mentors for their projects.
Maddy is conducting an environmental project to gain a better understanding of the thousands of milkfish (chanos chanos) found in Dampier Salt’s pond zero.
The milkfish are an introduced species which act as a natural filter, consuming the unwanted nutrients from the sea water used in the salt-making process.
Maddy’s study will examine the environmental factors that provide liveable conditions for the fish, including the pH level, conductivity, salinity, and algal levels.
A capture and tagging study will be conducted with a six-week gap.
Maddy hopes to capture and tag at least 50 fish, but the angling challenge will be seeing how many of the same fish can be recaptured after the six weeks.
One hundred tags have been donated to Maddy’s project by members of the King Bay Game Fishing Club.
St Luke’s student Dylan Muller, 15, is investigating what the strongest cable-stayed bridge design is.
There have not been many studies into the topic, so Dylan will look at one aspect, cable angles, as a basis for his experimentation.
This experiment will test the variable of cable angle in relation to strength.
St Luke’s student Avinash Sudhakaran, 15, will measure the output and quality of greywater using different filters to see if a garden drip irrigation system using treated greywater would be a cheap and efficient solution for reducing water consumption.
Several studies have been done in Australia where researchers have tried to discover techniques to reuse greywater efficiently.
The experiment will look to improve on previous trials to enable greywater reuse in the Pilbara.
