Angelina conducted a novel investigation into strategies to remediate oil spills using ferromagnetic nanoparticles and algae. Angelina successfully magnetised algae that was then able to be used to degrade oil in a simulated spill. This could then be removed using a neodymium magnet. Trialling different amounts and strains of algae, Angelina established that the Scenedesmus obliquus strain of algae was the most effective in degrading the oil, and the most effective amount of algae was a volume 1.5 times that of the oil.

Google Maps for space! Callum designed an application to calculate the path a spacecraft would take to move between planets using a transfer orbit or for travel to other star systems under power. He noted that, while government space agencies have dedicated systems for these calculations, his software offered this opportunity to everyone, with an interactive and user-friendly graphical interface. Callum will be the first Young Scientist entrant in the Mathematics category at ISEF.

Eliza examined the potential use of probiotics and synbiotics for the long- term treatment of lactose intolerance by analysing their effectiveness in breaking down lactose in milk samples into glucose and galactose. She measured the concentration of glucose as well changes in pH before and after the addition of probiotics or synbiotics as an indicator of their success in breaking down lactose. The results suggested that probiotics are effective in removing lactose from milk and can do so faster than synbiotic formulations.

Most Australian households put food waste into the garbage system, ending up as landfill. If Australians had backyard chickens, this waste could become a valuable source, and thus a part of the food supply chain. Emma aimed to determine how much food waste a chicken can process in both contained and foraging environments and what other benefits flow from this. The chickens produced nutrient-rich manures that can replace synthetic fertiliser and can condition the soil.
