Our department has an observatory on the rooftop of our building. It houses a 16-inch reflecting telescope, and some smaller ones. We use them in our astronomy courses to teach and train students basic techniques. In this programme, we will introduce the observatory, and use the main telescope to observe Mars, Jupiter and other celestial objects (subject to weather conditions). Participants could have a taste of observational astronomy.

Light pollution is a global environmental issue in which excessive artificial outdoor lightings affect the natural environment and the ecosystem. Among different forms of light pollution, light trespass needs immediate attention due to its potential adverse impacts on human health. The problem of light trespass is particularly evident in a densely-populated metropolis like Hong Kong. Using Artificial Intelligence (AI), computation methods are developed to detect, classify and quantify the light sources in images and videos taken at the street level. Results can be used as a light condition analysis for analysing whether light emitters are sourced from commercial buildings or street areas to determine the effects of light pollution on residents’ views. As a citizen science project, members of the public are encouraged to contribute images or videos via a mobile app to expend the coverage of the study. The lecture introduces light pollution, citizen science projects and the research conducted by the University of Hong Kong.

This activity is supported by the RAE 2026 Fund of The University of Hong Kong and received funding from the Environment and Conservation Fund (Project ID: 113/2022) of The Government of the Hong Kong Special Administrative Region.

‘What is DNA? What is genetics?’ Sik Sik Yuen Biotech MobileLab (BML) Program offers a series of programs and workshops about DNA and genetics in HK SciFest 2025. This workshop introduces the unique structure of DNA, the basics of genetic variation and genetic disease to the students. At the end the participants make their own DNA model designed and produced by BML to enhance their understanding of genetic variation using their eye colour as the example. Participant will have the DNA model after the workshop.

The GEO will organise the “Slope Safety Parent-child Carnival” at Hong Kong Science Museum.  Families are welcome.  In addition to display panels introducing slope safety in Hong Kong, there will be various interactive game booths including smart sandbox for demonstration of function of a rigid barrier, and VR games for visitors to take part in a virtual tour to the Hong Kong Geopark.  This is a chance for members of the public to come and join with their children to learn more about slope safety, geotechnical engineering and Hong Kong geology, while having fun from the games.

What is DNA? What is genetics? Sik Sik Yuen Biotech MobileLab (BML) Program offers a series of programs and workshops about DNA and genetics in HK SciFest 2025. This is a workshop to allow the publics to learn about the cell structure of prokaryotic and eukayotic cells and genetics. We will introduce a simple and locally developed method to extract DNA in bacterial cells. At the end, the participants can see and touch these important genetic materials of all living organisms.

What is DNA? What is genetics? Sik Sik Yuen Biotech MobileLab (BML) Program offers a series of programs and workshops about DNA and genetics in HK SciFest 2025. This is a student workshop to learn about different kinds of microorganisms, and their relationship with humans, and brief introduction of RNA virus and COVID-19. To check the effectiveness of their hand-washing habit by using fluorescent gel, and understand the importance of hand washing for preventing the spread of diseases, especially during and post- COVID-19 era.

The exhibition aims to provide participants with foundational knowledge and concepts of Gerontechnology. Visitors will explore and experience products across six key areas: health care, dinning, living, transport, exercise, and learning. Among these products, some of them are prototypes invented by the younger generation in Hong Kong. At the showcase, staff of the Jockey Club Gerontechnology and Smart Ageing in Place (GTSA) Project and Gerontech ambassadors will introduce these innovative products and facilitate hands-on experiences that allow participants to engage directly with each item, thus to enhance their understanding of how technology can improve the lives of older adults. This interactive approach will foster deeper insights into the applications of Gerontechnology and encourage informal discussions about its potential benefits in various aspects of daily living.

CityUHK Exhibition “Story of the Ocean Giants: Cetaceans and Sea Turtles” explores the life journey of cetaceans and sea turtles. Under the “One Ocean-One Health” paradigm, the health of aquatic animals is interconnected and inseparable with the health of the marine environment and us humans. The Aquatic Animal Virtopsy Lab at CityUHK investigates the biological health of the ocean sentinels, i.e. cetaceans and sea turtles, using multidisciplinary approaches, including visual health assessment, virtopsy and conventional necropsy. For the first time, with real specimens and true-to-scale models, alongside digital displays using state-of-the-art technologies showcased in this exhibition, you will learn more about these ocean giants up-close, what AFCD, CityUHK and regional collaborative efforts paid on holistic health assessment of cetaceans and sea turtles, and what can we do to protect them and allow them to thrive.
