2023 STANSW Young Scientist Awards Presentation Ceremony
Scientific Investigations 5-6
Zachary Collins , Sebastian Cortes & Christopher Paige , St Patrick ' s Catholic Primary School , Sand Tobogganing
Zachary , Christopher and Sebastian enjoy sandboarding and were keen to find out how they could alter the speed by varying the toboggan ’ s shape , person ’ s weight or slope . Overall , they calculated that a medium weight increases speed and distance compared to a super light or heavy weight . The angle of incline varied the speed with the steeper slope having the slower speed .
Amy Dou , PLC Sydney , Egg-ceptional Adaptations
Amy investigated if the shape of the guillemot egg made it less prone to be blown off the cliffs in which the guillemot bird lays its eggs . She 3D-printed eggs replicating those from a guillemot bird , hen , ostrich and an owl and compared the distance they each moved when rolled or pushed by wind on a sloped surface . Amy ’ s results concluded the shape of the guillemot egg made it more resilient to the windy conditions of the cliffs .
Tiffany Kouhis , PLC Sydney , Salmon Farming : Too Hot , Breathe Not
Tiffany was curious to discover if the water temperatures where Atlantic salmon are farmed affected the oxygen content and algal growth of the natural waterways . Her research showed that increased water temperatures lead to increased algae growth and decreased oxygen in the water . Tiffany concluded that farming salmon in natural waterways changes the water conditions not only for the salmon but for all fish and the environment .
