Registration open.

A 50 minute, multiple choice competition testing science knowledge, critical-thinking and problem-solving skills. Questions are set in real-life, contemporary contexts, making them relatable (and interesting)!

The Big Science Competition is an easy way to challenge students from Years 7 to 10 and track their performance against state or national averages. Competition questions are aligned with the Australian Curriculum – Science.

Students receive a certificate indicating their performance and schools will receive comprehensive reporting on student results compared to class, school and national averages.

Sitting the Big Science Competition could lead to selection in science extension programs including the Australian Science Olympiads and Curious Minds – girls in STEM.

This year, students can win one of four great prizes, including an Apple iPad*! Don’t hesitate.

Registrations close Friday 5 May.
