Communicating scientific ideas and discoveries to the world is a tricky task.Ìý

This film competition encourages school students to communicate a scientific concept in a way that is accessible and entertaining to the public while painlessly increasing their science knowledge or, as Dr Karl likes to say, "Learn something without even noticing".Ìý

This year, there have been some of the most amazing entries yet. Find out more about our finalists and the amazing content they've created below.

University of Sydney Sleek Geeks Science Eureka Prize — Primary

Charlotte L., PLC Sydney, NSW

Cattle farming produces large amounts of the greenhouse gas methane, but a possible solution might live in the sea. InÌýA More Polite Belch,ÌýCharlotte uses humour and engaging graphics to show that by adding the red seaweed, Asparagopsis, to animal feed, the digestion of cows and sheep can be modified to drastically reduce their methane output.

Zara M., PLC Sydney, NSW

In Stem Cells - Changing the Way We Heal, Zara uses colourful animations, expert interviews and an original experiment with a flatworm called Bob, to demonstrate the regenerative capacity of stem cells. She explains how pluripotent stem cells can become any type of cell in the body, with potential to promote growth and healing. See the video .Ìý

Genevieve S., Bucasia State School, Qld

InÌýAdaptation: Now That's Change!ÌýGenevieve examines how animals fit into their environment and what they must do to survive if their habitat changes. Combining graphics and close encounters with cuddly — and not-so-cuddly — creatures, she shows how adaptations happen over time and the sort of features that develop to help animals thrive.

University of Sydney Sleek Geeks Science Eureka Prize — Secondary

Marissa C., Somerville House, Qld

Finding Nemo is a fun movie but inÌýSex Change in Clownfish,ÌýMarissa shows the science is a little fishy. Combining expert opinion with graphics to map their complex reproductive hierarchy, she explains that all clownfish have male and female reproductive organs. This means if a breeding female is lost, the dominant male can switch sex to replace her. Watch the video .Ìý

Iestyn R., St John's Anglican College, Forest Lake, Qld

Brain scanning technology shows that the human brain can adapt throughout our lives. In his filmÌýNeuroplasticity - You Can Change Your Brain, Iestyn uses colourful graphics to explain how neurons connect via synapses. Through everyday examples, he shows that when connections become crowded with data, learning prompts an editing process that makes space for new information. Watch the film .Ìý

Aidi H., Tara K. and Ellen Z., Lauriston Girls' School, Vic

Aidi, Tara and Ellen tell the story of COVID-19 variants through song.ÌýChanging CoronaÌýdescribes how virus mutations are caused by errors during reproduction.
