CityUHK Science Video Competition 2025
Science is all around us. Can you explain a scientific principle or phenomenon in a simple and clear way for those who may not be familiar with science?
The CityUHK Science Video Competition 2025 is open to all full-time secondary school students in Hong Kong. Our goal is to spark public interest in science and inspire creative thinking. Participants are invited to create innovative videos, up to 5 minutes long, that explain or demonstrate a scientific principle or phenomenon in an engaging way. Whether it's a concept you learned in school or a phenomenon that excites you and isn't typically covered in class, we want to see your enthusiasm and creativity shine. Winning videos will be those that effectively communicate complex scientific concepts in a scientifically accurate, original, engaging, and imaginative manner. Think outside the box—consider using dance, drama, props, animation, and more to make your video interesting and creative!
