Robotics, 3D projects, coding, astronomy and the solar system, engineering and the environment were featured.

Science head teacher Aiden Stelling said the school identified the need for enrichment extensions for gifted, talented and those passionate about special projects.

"This showcase was identified as part of our enrichment extension," he said.

"Students have to apply to participate and are given 100 hours per hour - two periods per week - to undertake this work.

"The aim is to give students the time to develop a project through time management, access to mentors and guidance.

"However, there is also accountability, and goal or end sight, where students have to present, to showcase their projects."

Mr Stelling said mentors, teachers, parents and students from top classes in years 7 and 8 were invited to the showcase.

He said the showcase applies a level of accountability and pressure on the students.

The special interest project students utilise the technical expertise from within the school.

"The staff at the school have assisted the students along this path," Mr Stelling added.

One of the groups, Ebony Nicholas, Elizabeth Legge and Shae Bradford, had spent at least two years on their football-playing robots.

"Our challenge was to create and construct the robots - which is a new version of robot construction for the school," Elizabeth said.

"Ebony was our main coder while Shae provided her skills in 3D modelling and laser printing. My role was the electrical circuits.

"There are now a couple of all-girl team in robotics at the school. But more girls should get involved," she said.

All three said they were passionate about robotics.

At robotics competitions, the year 10 trio are often pitted against year 12 boys from private schools.
