Primary and high school students from across Australia have been celebrated for their creative science films in the 2025 University of Sydney Sleek Geeks Science Eureka Prize.

This year, students were asked to use the theme 'above and below' to create two-minute films that communicate scientific concepts in accessible and engaging ways.

School students from all across Australia submitted their unique, creative and entertaining responses, resulting in two winners, six finalists and 19 highly commended award winners who were celebrated during the Eureka Prizes ceremony held on Wednesday 3 September 2025.

The prizes are named after the Sleek Geeks – Dr Karl Kruszelnicki, Julius Sumner Miller Fellow at the University of Sydney, and Adam Spencer, Mathematics and Science Ambassador at the University of Sydney. 

Primary school finalists

Winner: Keira P., PLC Sydney, NSW

Keira, in Year 3, has designed and conducted an experiment to discover which thread count of cotton bedsheets is best at keeping out dust mite poo, while still allowing air through. Dusty’s Mitey Poo – Hidden Below includes lots of information about dust mites and features Keira in a ‘mitey’ costume.

Secondary school finalists

Winner: Sophie M., St Philip's Christian College, NSW

In Swing Smart to Stand Tall, 15-year-old Sophie explains how a giant pendulum helps stabilise a skyscraper during earthquakes and typhoons. Through clear narration and straightforward diagrams, she explores how engineering can protect lives above ground from seismic forces that originate below – bridging physics, design and the mechanics behind towering structures.

Runner up: Noah C., Aiden K., Paige T., Tahlia W., and Madeline Z., Viewbank College, VIC

Combining handmade graphics, animation and engaging narration, The Science of Talking Trees reveals how trees communicate through both root networks and airborne chemicals. By exploring the hidden ways trees interact with their environment, the Year 10 students highlight a complex natural system often missed by those who only see the surface.

Runner up: Daisy G., Grace O., and Jacquie Z., Lauriston Girls' School, VIC

In The Brain Beneath Your Feet, these Year 11 students explore the hidden intelligence of fungi through the underground mycorrhizal network – often called the ‘wood wide web’. Using clear narration and simple animation, the film explains how fungi communicate, share resources and support trees through vast, unseen networks.
