ASSOCIATION NEWS 2017 STANSW Young Scientist ISEF (continued) Mary-Anne’s project looked at the distribution of the species in relation to a creek and found out that it was elevation that greatly affected where the native species were located. Her findings can be used in regeneration projects, not only in Australia but all over the world, and a lot of people are really excited in her findings. Eleanor Lawton-Wade, PLC Sydney, In hot water Sponsored Award: King Abdul-Aziz & his Companions Foundation for Giftedness and Creativity Award Eleanor’s project was a quantitative study of the effects of rising freshwater temperatures on water chemistry and the productivity and biomass of photosynthetic and respiratory processes. Over a month she looked at two mesocosms, one at a baseline temperature and one at a temperature which is the extrapolated temperature in the next hundred years. Her results are a series of chemical and biological samples to assess the impact of that temperature rise as well as to develop a mathematical model that projects what these changes mean in the long term. Mary-Anne’s favourite part of her trip was going to the California Science Centre, and seeing the actual Endeavour Space Shuttle on display and hearing the story of one of the workers who helped service it. Rebekah Kang, PLC Sydney, Slick and Clean – An investigation into how magnetite can be used with organic sorbents in oil spill clean-up 3rd Place Grand Award: Environmental Engineering Rebekah looked into how magnetite can be used with organic adsorbent material in the oil spill clean-up process. Rebekah sourced magnetite from a local beach. She simply ran a bar magnet through the sand at Meadowbank Wharf and she then sprinkled that magnetite over a mixture of oil and water. She had a boom made out of vinyl, inside which she had six neodymium magnets. The boom was wrapped in a controlled mass of a hydrophobic organic solvent material. The three different organic solvent materials that she tested were human hair, feathers and straw. The magnetic boom was rolled across a mixture of water, oil and magnetite. The magnetite and the oil combined, forming a loose colloidal suspension. As the boom was rolled across the surface of the mixture the magnetite was drawn into the neodymium magnets in the boom and at the same time the oil moved with the magnetite and so was adsorbed by the organic adsorbent material surrounding the boom. Eleanor’s favourite part of ISEF was just the people – “Science just doesn’t operate in a laboratory, Science is about forming relationships and about forming memories and that is what this whole experience has been. It has been fun and it has been serious, but it has been predominantly about people and how we share ideas and share memories and I have loved every single part of that.” Maddison King, Meriden School, Clever GIRL (Global Intelligent Rip Detector) Maddison created the Clever GIRL. GIRL stands for Global Intelligence Rip Locator and it is also called GIRL because girls are cleverer than boys. So basically what happens when a rip goes through the turbine, it spins faster. The turbine drives a generator, calibrated such that a light switches on when the water speed reaches 0.7 m/s. It uses basic physics principles but it does make for an innovative product. Maddison most enjoyed meeting so many people from all over the world and she adds them onto social media so she can stay in contact with them for ages. Rebekah’s favourite memory of the trip involved one of the judging sessions where she quoted a particular research study which she referenced in her project; it happened to be the research performed by that particular judge, which was really special for both of them. 9 SCIENCE EDUCATIONAL NEWS VOL 66 NO 4
