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.
