Playground surfaces: Force absorption capacity of sand
To improve the safety of playgrounds, Benjamin investigated the suitability of sand as a playground surface. His results determined the depth and type of sand that should be used for maximum absorption and safety.

Sakhi Doshi
QLD - Queensland Academy for Health Sciences
The effects of heavy rainfall on recreational use of waste water
Sakhi examined the effects of the annual heavy rainfall events on the Gold Coast water quality. As waste water is released into areas where human recreation occurs, the confirmation of the presence of E. coli and Bacteroides fragilis bacteria was concerning.

James Gabor
NSW - Chevalier College
The effects of nerve regeneration on nerve function and structure
Attaining an understanding of nerve regeneration would greatly benefit medicine, specifically following spinal cord injury. James' project used earthworms to evaluate nerve structure and function following bisection. The results demonstrated that even though there were some changes in nerve structure, there was still a return of nerve function.

Liam Grieve
TAS - Burnie High School
Troubled waters
Liam investigated the use of plants to remove nutrients from water. By simulating nutrient rich wetland environments and recording concentrations, he found that wetland plants have the potential to preserve waterways.

Cynthia Sin Nga Lam
VIC - Balwyn High School
Applications of titanium dioxide photocatalysis
Cynthia investigated the applications of titanium dioxide photocatalysis on the removal of organic waste in water and the generation of hydrogen gas. The method was found to be efficient, eco-friendly and can be easily implemented due to its simplicity and low cost.

Phoebe Lewis
QLD - Trinity Anglican School
The effects of pH on the calcite carapace of ostracods
Phoebe was interested in the detriment that excess carbon dioxide could cause to the earth's delicate ecosystems, especially to those creatures hidden from the public eye. By immersing calcium carbonate chips in solutions of altered acidity, Phoebe investigated the effect of increased anthropogenic carbon dioxide on the calcite carapace of ostracods.

Angela Liao
ACT - Lyneham High School
Something to chew on: Effects of gum’s flavour on salivary flow rate and pH levels
Saliva is an important factor of oral health and the benefits of chewing gum are well known. Angela's study investigated the effects of gum flavour on saliva flow and pH. Chewing of all gums tested stimulated saliva flow and neutralised pH levels, indicating that chewing any of the gums would have comparable benefits.

Michael McLure
QLD - Biloela State High School
Investigation into the effectiveness of cleaning products on peanut protein
In Australia, many children have life-threatening peanut allergies. Michael's project used protein detection equipment to examine how effective common cleaning products were at cleaning surfaces contaminated by peanut butter.

Somya Mehra
VIC - Balwyn High School
Biosynthesis of ethanol
Bioethanol is a fuel made by fermentation of sugars. Most microorganisms that produce ethanol by fermenting sugars cannot break down xylose (wood sugar), though some treatments can break xylose down further so it can be fermented. Somya investigated the effect of varying levels of xylose on ethanol yields and found that higher concentrations could potentially decrease ethanol production rate.

Shivankaran Muraleedaran
QLD - Trinity Anglican School
Efficiency of wireless power transmission
Shivankaran tested the efficiency and viability of wireless power via strongly coupled magnetic resonances. While he discovered that this method was not suitable for large scale use, the feasibility of this method may improve in the future.

Lewis Nitschinsk
QLD - Queensland Academy for Health Sciences
The optimal reclamation point of phosphate from waste water
Phosphorous is a commonly used chemical in the production of industrial products. As it is non-renewable and highly used, Lewis investigated the optimal reclamation point of phosphate from the water from a treatment facility of a factory through chemical precipitation. Results indicated that the highest percentage reclamation was in the untreated water sample.

James Tucker
TAS - The Hutchins School
CPU overclocking vs increasing RAM
Technology is advancing rapidly and there is constant pressure for consumers to upgrade to new computers to keep up to date. James' project showed that overclocking the CPU was a more effective upgrade than adding RAM to extend the useful lifespan of an average user's computer.

Ranadi Vincent
QLD - Queensland Academy for Health Sciences
The effects of supplying nitrogen to hydroponically grown soybeans
Ranadi investigated the effect of varied supplemental sources of nitrogen on the growth of soybean plants. She looked at the effects of chemical fertiliser, fish fertiliser, rainwater and inoculation with nitrogen fixing bacteria on the development of the plants. She found no significant difference in soybean growth across the experimental conditions, suggesting that growers may not need to supplement nitrogen as much as they have been.
