Science Research Award Highlights
A science research team has been formed by three G.T. students from Grade 9 which has won the Merit Award in the 20th Hong Kong Youth Science & Technology Innovation Competition (HKYSTIC) 2017-2018. The event was held on 13-15 April, 2018 at the Hong Kong Science Park which included the Project Booth Set-up, the Final Judging cum Public Exhibition and the Prize Presentation Ceremony.
Background Information of HKYSTIC
Since its launch in 1997, the Hong Kong Youth Science & Technology Innovation Competition (HKYSTIC) is now the largest and most popular STEM competition in Hong Kong with over 4,000 applicants from nearly 350 schools participating in this annual event. Our research team has participated in the Research and Invention (Junior Section) category. Participants can submit either a research or an invention.
Our Project Overview
The research project has been conducted continuously for 5 months, from November 2017 to April 2018, in our laboratories. The invention of our research team is “Antibacterial Nano Silver Shoe Pad”. The idea of the invention is from the experience in our research team leader, Jeremy Wan’s daily life. In a rainy day, Jeremy forgot to bring his umbrella. His shoes were all wet due to the heavy rain. When he got home, he noticed that his shoes were very smelly and the odor could not be gotten rid of. As Jeremy’s experience was disturbing and embarrassing, we brainstormed some solutions to clear the bad odor.
Shoe odor is a big problem for many people. Eventually, our students decided to invent an insole containing chemicals that can kill microbes. After conducting some investigative studies and searching for research publications on various alternatives: 1) using tourmaline to charge UV light; 2) to create ozone; 3) designing a drainage system; 4) using activated charcoal; 5) using alcohol; and 6) using nano silver, we have selected nano silver to kill the bacteria & fungi. With it, the problem of shoe odor will be solved.
We have found that silver solution is an efficient and efficient way on killing brevibacterium linens which means that our shoe pad is a good way of preventing the shoe odor. We hope in the future we can extend this technology to other products, e.g. spray, cloth fibre, laundry detergent, so that our products can help the needed, especially the elderly and the disabled around the world.
Profile of Our Science Research Team
Jeremy Wan Cheuk Heng (9C): The team leader; possesses the “gene” for scientific research; has intense interests in science; with strong presentation skills.
Ricky Chan Kin Lun (9C): Embraces challenges; possesses strong analytical skills and organizational skills; with strong reasoning and critical thinking.
Ivan Chong Cheuk Ki (9C): Possesses strong scientific mindsets including systematic and logical thinking; strong language skills including report and video scripts writing skills.
Through this scientific investigation journey, our students have not only acquired the scientific knowledge, but also undergone the life cycle of scientists. They have faced difficulties, challenges and failures in their scientific investigation. They were not doing experiments which had been previously well-proven as in their regular classes. Instead, they were exploring multiple possibilities and dealing with open-ended research with uncertainties. They spent lots of time and effort reading research journals, doing repetitive experiments to find out the pattern of bacterial growth and writing research reports during school holidays.
Though they have encountered various hardships throughout the scientific journey, the outcomes are very well received. And if fact, the more frequent they failed, the more joyful they experienced when they finally got the expected experimental results successfully, and the higher level of satisfaction they gained.
Another valuable experience they have gained from the scientific investigation is the learning of time management. Sometimes, they might find challenging to manage both academic work and science research at the same time, especially during assessment periods. But actually, it is real-world training on multi-tasking and prioritization. They will certainly face this kind of scenarios in the coming future when studying in university and working in society.
Finally, they were able to manage both very well and the results were very encouraging. They have shared with me that there were synergy through doing scientific research and it has benefited their academic work. I appreciate their time and effort contribution to the scientific investigation very much. And their endeavors have been highly recognized.
Affirmations from parents also have played a very important part in supporting their children doing scientific research via their presence in the public exhibition or prize presentation ceremony. And I have been very thankful to learn from their parents that they have made breakthroughs in problem solving skills and overcome bottlenecks in learning.
Gratitude & Thankfulness
Like other subjects, science is a subject which needs a continuous immersion from junior forms and in primary school. It also has integration with knowledge from other subjects. A student will not have intense interest in scientific investigation overnight. The fundamental education is very important for our students. And we would like to show our gratitude to all parents to let us coach their children in the open competitions.
I am proud to have such high-quality students to participate in the science competitions. And I am very delighted that I have witnessed these students grown throughout their research journey.
Science research team needs research atmosphere, peer support and adequate coaching. Our forward plan is to establish a more sophisticated research environment to gather those students who are interested in scientific investigation. In the coming academic years, we will collaborate with universities to do scientific research in the university laboratories. We will continue to coach our G.T. students for the accomplishment of love, creativity and task commitment and nurture them to be our future leaders.
