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.
Isaac designed a waterproof device that can be worn as a belt by rock fishers and communicates wirelessly and automatically with another component which stays out of the water. Isaac’s device includes an innovative combination of different technologies including a GPS module and transceiver, a tinysine 3g shield and Arduino UNO coding. The device could potentially save the lives of rock fishers who get swept into the water.
Smoke alarms can save lives. However when they are triggered unnecessarily it can reduce their effectiveness. Kelvin investigated the effect of higher humidity levels on smoke alarm triggering and found that the alarms were indeed more sensitive in the presence of water vapour. He then used a simulation software and designed a prototype to determine that the incidence of false alarms could be reduced by comparing the signal from the smoke alarm and the humidity sensor, while still triggering in the case of an actual fire.
Macinley continued to develop and test the clinical viability of her invention of a system to reduce the radiation dose during radiotherapy for treatment of breast cancer. The system combines a physical shield made from overlapping copper pieces to block radiation to non-treated areas and a strong magnetic field to deflect harmful electrons out of the radiation beam, while not interfering with the treatment. This system will help to minimise the negative short and long-term side effects of radiotherapy, and potentially improving cancer survival.
Olivia built and tested a monitoring system in which the ammonia, pH, and temperature levels of water are measured. The data is then able to be sent to a Bluetooth device to be logged into a relevant program. Her innovative portable system is convenient in terms of data communication, the range of aspects of water quality measured, and transportation in case of a
location change. Applications of the system could include public lakes and groundwater systems on agricultural land, as well as aquaponics and fish farming.
Lead contamination of drinking water poses very serious health risks to humans, and coriander has been shown to be effective at removing lead from animal bodies. Sophie investigated which form of coriander – fresh leaves, cut stems or dried leaves – was the most effective at removing lead from contaminated water. Her extensive investigations found that fresh leaves were the most effective.
Our team of excited young students and accompanying chaperones, family and teachers are making final preparations to travel to Phoenix, Arizona U.S.A. to represent Australia and NSW at Intel ISEF 2019!
Our team of 9 ISEF delegates and our BroadCom Masters representative will compete with 1800+ students from all over the world (80+ countries) at ISEF (International Science and Engineering Fair) – the largest science fair for high school students in the world. The team includes our first Mathematics delegate and will be accompanied by teacher chaperones from the Young Scientist committee as well as the Rural Young Scientist Teacher Ambassador.
The range and depth of the student projects is truly inspiring – please visit back soon to see profiles of each delegate, with a description of their projects.
We will be keeping in touch while we are in Phoenix via a range of social media platforms. Please follow our progress via
Our team of 9 students and 4 chaperones are headed to Phoenix, U.S.A. in May to represent NSW and Australia at Intel ISEF 2019 (The International Science and Engineering Fair). The team consists of:

Eliza Martin, PLC Sydney: The Development of a Novel Treatment for Lactose Intolerance Using Synbiotic Formulations
Sophie Angus, PLC Sydney: Using coriander to remove lead from contaminated water
Olivia Arvanitis, Meriden School: Water Monitoring System
The team will also include our Broadcom Masters representative
Dean Chapman, MacAuley Catholic College: To grow or not to grow….that is the question
We are grateful for funding from our new sponsors: The Office of the NSW Chief Scientist & Engineer (through their Supporting Young Scientists Program SYSP) and CrookEd Science along with our Principal Sponsor The Sapphire Foundation for making it possible for us to send the whole complement of 9 projects to ISEF.
Please return back for more posts highlighting each of our talented delegates’ projects.
