Benjamin investigated how the distribution of mass around a pendulum would affect its motion and modeled a method of swinging that could be used by disabled persons. The inspiration for this experiment came from observing how the motion of a swing was generated purely by a person moving their body and how this movement restricted the use of swings to able bodied persons.

Christy investigated the effects of varying extracellular potassium and sodium ion concentration on apoptosis (programmed cell death) when cells are exposed to ultraviolet-B radiation. Varying the concentrations of these particular ions in a cell's extracellular environment may play a crucial role in the activation or inhibition of apoptotic pathways and carcinogenesis. Results indicated that a higher concentration of potassium ions decreased the rate of apoptosis, whilst a higher concentration of sodium ions increased the rate of apoptosis.

Claire investigated the factors which affect sand’s collapse and angle of repose in a simulated long jump landing. She found that long jump distance loss is minimised through increased sand moisture content, but is also dependent on sand’s physical characteristics of grain size distribution and shape. Her results can be applied to long jump competitions to improve measurement accuracy.
Florence investigated the effect of nutrient starvation and salt stress on antibiotic tolerance. She determined that decreasing nutrient concentrations and increasing salt concentrations could contribute towards decreased susceptibility of Escherichia coli to a range of antibiotics. This is of particular importance due to increasing concern of antibiotic misuse in medical situations, leading to antibiotic resistant bacterial strains.

Many fuels produce harmful levels of greenhouse gasses and come from non-renewable sources. Using fermentation chambers and an ethanol sensor, Hannah investigated the use of globally abundant weeds for fuel. It showed that certain weeds such as lupin can produce very high levels of ethanol and hence the possibility for their use as a bioethanol fuel is promising.

Jeeyoon determined the percentage of Organoclay® in sand that is required to safely prevent hydrocarbon contaminants from leaking out of underground fuel tanks at petrol stations. Hydrocarbon contamination in groundwater is a concern as exposure to compounds contained in hydrocarbon can lead to serious health problems, and Organoclay® has been developed to absorb the contaminants in petroleum.
The rising levels of greenhouse gas emissions are a global environmental threat, but the emissions from motor vehicles may be combated with renewable biodiesel fuel, if a suitable source is found. Joanne researched the feasibility of using readily available waste vegetable oils as the basis for biodiesel including the optimum oil to be used considering its susceptibility to degradation after usage.
Kimberley investigated the effect that pitch, surface area of roofs and the positioning of openings had on the uplift of a roof in a windy environment. Her results can be used to make recommendations in roof and house design to lessen the impact of cyclonic winds on households in cyclone prone areas such as Far-north Queensland.

The effects of biofumigation on fungi examines whether or not some plants have the ability to biofumigate soils. Liam used two types of fungi, both of which can infect wheat and two bio-fumigants to inhibit the growth of the fungi. His results showed the potential plants have to biofumigate soil and decrease reliance on man-made fungicides.
Honeybee silk protein can be made artificially at an industrial scale, but further work is needed to purify the protein and characterise new silk biomaterials. Nick’s project demonstrated that honeybee silk can be substantially purified by simple heat treatment and materials prepared from silk protein can be used for controlled-release of small drug-like chemicals.

Weeds are a major problem affecting many countries including Australia, annually accounting for millions of dollars in losses. When chemical controls are used, wheat also suffers in yield, adaptability and quality, so herbicide resistant is sought. Nripan identified Imidazolinone resistant wheat individuals within the Intergrain breeding program.
Patrick realised that commercial cotton masks are unable to filter toxic pollutants such as ammonia from the air. He selected five materials that displayed promise and tested them by packing the materials inside plastic straws before passing Ammonia gas through the straw into water. Ammonia was detected by a change in pH of the water. Lastly, the best material was tested at increasing amounts to examine the efficiency improvement.
Treatment of industrial wastewater from coal mining by traditional methods can have several disadvantages and high costs. Sang Won investigated an alternative treatment of waste water pollutants (lead, nitrate and ammonium) using marine microalgae. Results showed marine microalgae were effective in removing pollutant; with greater efficacy when several algae were used in combination.
Used cooking oils (UCOs) are widely regarded as viable feedstock for biodiesel production. When heated, and reheated, the oil undergoes hydrolysis and Free Fatty Acids (FFAs) are formed. These FFAs reduce the yield of biodiesel significantly. Identification of the UCO least prone to forming FFAs after repeated heating will be beneficial to the industry.

William assessed the effects of increased atmospheric CO2 concentration on canola and wheat plant growth. The plants were grown in two atmospherically controlled greenhouses, one at an ambient CO2 concentration, and the other at 45% increased CO2 concentration. The elevated CO2 concentration caused 30% and 10% growth increase in the canola and wheat respectively.
Redeemer Baptist School recently led a medical mission to remote villages in Papua New Guinea. Sensitive equipment was damaged because of the jolting it received whilst being carried. The Trek Mate was designed to safely carry the equipment, particularly a solar generator from village to village and over rugged mountain trails, using the traditional method of transportation.
Breathe Easy is a project that has identified an alarming consequence of leaving your car’s air-conditioning on recirculation: inadequate control of carbon dioxide levels inside the cabin. Chanum designed the Automated Vehicle Interior Air Quality Regulator to automatically switch the car’s ventilation when safe levels of CO2 are surpassed, bringing in fresh air and maintaining ‘safe’ levels as per the Australian Standards.

Living in North Queensland is a privilege, but at a cost – cyclones. JCU’s cyclone testing station reports and tropical cyclone Yasi reports have shown that the weakest point in any house is the roller door. Danae developed a simple “Do It Yourself” kit that is easily applied, accessible and removable to the susceptible area that could eliminate this problem.

Ethan’s project, Magnetro, improves radiotherapy treatments through optimising a magnetic field to "sweep away the bad stuff". The electron contamination (i.e. “bad stuff”) produced by the X-Ray beam treating the tumour at depth, can cause skin burning and increase the risk of new cancers forming. Magnetro creates a stronger and more uniform magnetic field allowing for the best method of electron contamination removal.

Radio telescopes have been observing pulsars (ultra-dense remnants of collapsed supernovae) for many years. Oliver built and tested a unique physical pulsar model and receiving system, emulating a telescope and supercomputer. Readings from the model were compared to observations of actual pulsar emissions made by astronomers validating the model and their theories.
