concluded successfully with

Two Hong Kong Secondary School Teams winning Grand Prizes


The Global Youth Science and Technology Bowl (GYSTB) 2022, organised by the Creative Education Unit of The Hong Kong Federation of Youth Groups (HKFYG), was successfully held on Facebook live last weekend. There were 80 shortlisted overseas and local high school teams, who showcased their amazing scientific findings and innovative ideas to solve everyday problems under the theme of Sustainable Development. Nine Hong Kong teams made it to the Finals, of which Two Hong Kong Teams took home the Grand Prizes – Silver and Bronze Award in their respective categories.


Team from South Africa, seized the Grand Prize – Gold Award in the Physical and Engineering Category with “Automated Inflation and Pressure Regulation for Recreational and Professional Cyclists”. This is an invention that helps cyclists quickly inflate their tires without climbing off their bicycles. Another Gold Award winner from South Korea, won with his “PESH: Piezoelectric Energy Harvester Using Sloshing-induced Impact Force”, a novel sloshing energy harvester which generates energy when its piezoelectric patch is hit by a violent water flow. Hong Kong team from Christian Alliance S W Chan Memorial College won the Grand Award – Sliver Award with their project “EMG Rehab System – A Package for Stroke Self Rehabilitation”, they invented a transitional package based on orthodox rehabilitation treatment for stroke patients.


In the Biology and Chemistry Category, two Singaporean teams won the Grand Prize – Gold Award. Team with project “Minimally Invasive Annuloplasty Using Shape-Memory Materials” constructed novel shape memory rings using Nitinol alloy and MMA-PEGDMA polymer to reduce trauma of annuloplasty surgeries of valvular heart disease. While the joint winner won with their project “Effect of different NPK ratios on the mass and chlorophyll content of the kangkong plant”. The student found the ideal Nitrogen, Phosphorus and Potassium ratio to maximise crop yield to ensure adequate food supply and achieve economic benefits. Also, Hong Kong team from Queen Elizabeth School Old Students’ Association Secondary School got the Grand Prize – Bronze Award with their project “The Use of Brine Shrimp to Test for water pollutants” investigating the impact of different pollutants on the growth of brine shrimp.

The GYSTB 2022 attracted 125 school teams from 27 countries and regions, including the United States, Ireland, Sweden, South Korea and Singapore etc. Each team was comprised of not more than five students from Forms 1 to 6 (or equivalent).


The team developed their projects in relation to the theme of Sustainable Development, using theories from physics, engineering, biology or chemistry to investigate science topics or create innovative and practical inventions. They then presented their inventions or investigation projects to professional judging panels formed by academic and industry representatives. During the Judging, teams successfully demonstrated their understanding of scientific knowledge, resilience as well as presentation skills.


Kenneth LEE Kin-lok, Supervisor (Innovation and Creativity) of the HKFYG expressed his amazement at the level of innovation that each team showed. “It was full of surprises! I really found it encouraging that the students utilized their creativity and scientific minds to show their blueprint for sustainable development, and came up with innovative solutions to everyday problems. I very much hope that the students enjoyed every opportunity to exchange and learn, and will use this as a foundation on which to improve their problem-solving, resilience, communication and collaborative skills,” said Mr Lee. He also encouraged the students to persevere on their scientific research journey. 


An online voting campaign of the “Visitors’ Favorite Award” which has already begun will run until 26 June. The public are invited to vote for their favourite projects. Please visit for more information about the voting details, the winners, and their projects.


The GYSTB is organized by the Creative Education Unit of the HKFYG. The Competition is a showcase of global youth scientific achievement and innovation. The event aims to promote science and technology, provide a platform for global youth to develop their creativity and scientific mindsets, and facilitate the exchange of scientific ideas, interests and abilities among young scientists all over the world.
