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 analyzing 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 booth 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. Any opinions, findings, conclusions or recommendations expressed in this material do not necessarily reflect the views of the Government of the Hong Kong Special Administrative Region and the Environment and Conservation Fund.

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.

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.

This year, Nina Park will participate in the HK Scifest 2025, featuring an exciting exhibition booth that highlights its precious wood fossil collection and innovative sustainability facilities. Visitors can explore the fascinating characteristics of these collections through fossil slices and microscopic images, revealing intriguing facts that are often overlooked. This unique experience combines fun and learning, making it perfect for families and curious minds alike.

Join us to discover the wonders of nature and enjoy an engaging experience with history and science in a vibrant, interactive setting! Nina Park is excited to welcome you!

Smart "Flying" and "Travelling": Low-Altitude Economy Experience Zone

What is the Low-altitude Economy (LAE)? How can we use various aerial vehicles (such as drones) to makes our lives more convenient?

Hong Kong Applied Science and Technology Research Institute (ASTRI) will showcase a virtual autonomous vehicle driving game, a C-V2X technology interactive game and a drone display with the theme "Smart 'Flying' and 'Travelling'". We invite you to experience the driving game, learn about electric vehicle and autonomous driving technologies, explore how these technologies enhance road safety and convenience. You can also discover drone technology to gain deeper insights into the development of innovative technologies.

Welcome to visit our booth. Let's "drive the future" with ASTRI!

We have invited different primary and secondary school students to exhibit their STEM projects, allowing the public to share the joy of exploration, innovation and creation in the STEM field with local student scientists and inventors. Projects include winners of local and international awards.

Addressing Indoor Air Quality for a Healthier Future
This initiative focuses on addressing the environmental and public health risks associated with indoor air pollutants through scientific research and educational initiatives. The educational kit includes a comprehensive manual on IAQ monitoring techniques and instruments, enabling users to perform calculations, conduct statistical analyses, and compare data across various indoor environments.


Innovative Solution for Microplastic Pollution Detection
This invention advances the total organic carbon (TOC) analysis with an all-in-one sample pre-treatment device to efficiently and accurately assess microplastic (MP) pollution levels in different water samples. Compared with typical methods, this invention saved pre-treatment and analysis time by over 70%, and capital and operating costs by above 80% and 90%, respectively. Equipped with a web-based mobile app, users can monitor and control the pre-treatment device and collect real-time data remotely. It is applicable to determine MP mass representatively. Unlike other commonly used MP quantification methods, its accuracy is not affected by the complex nature of MP pollution and environmental conditions.

This program aims to introduce participants to the fascinating world of model organisms in scientific research. Throughout the session, attendees will explore the significance of model organisms in biological studies, gaining insights into how these creatures contribute to our understanding of genetics, development, and disease. Hands-on experiments will display for observing these organisms up close and learn about their unique characteristics.

Dive into the world of DNA and discover how model organisms, especially zebrafish, help scientists in their research. Kids will explore what DNA is and why it's so important and hands-on activities that make learning about genetics. Participants will get to conduct a fun forensic experiment, where they can see how DNA analysis works in real-life situations.

Have you ever heard birdsong in the streets or forests but couldn't find where the birds were?
