Garbage Recycling Robot	School	Topic	Abstract
10:00 - 13:30	HKTA The Yuen Yuen Institute No.1 Secondary School	Building Our Own Flight Simulator	The school-based aviation simulator construction project starts from an aviation course which equips students with fundamental aviation knowledge. In this project, students are given ample opportunities to exercise their initiative. For instance, when purchasing aircraft simulation hardware, the teacher is only responsible for communicating with the suppliers, allowing students to conduct research, select suitable components, and apply the 3D printing and laser cutting techniques learnt from school-based information technology lessons to create the necessary parts, and assemble them by hand. After finishing setting up the simulator, students can experience their own construction first then a further guidance is provided for students to conduct a reflection regarding rooms for improvement. By applying the knowledge acquired into their daily lives, students gain an understanding of the functions and design features of various computer components. They also have the opportunity to employ their drawing and modelling skills to continuously improve and maintain the simulator, laying a solid foundation for their aviation knowledge. This also paves the way for the future implementation of more aviation education programs within the school.

10:00 - 13:30	Ma On Shan Ling Liang Primary School	E-Meow	Hong Kong is facing the challenge of an aging population. At the same time, Hong Kong also facing the decline in birth rates, leading to an increasingly severe issue of solitary elderly. Inspired by the challenges, the team developed E-Meow, a multifunctional smart pet that uses AI to learn about the living environments and movements of elderly individuals living alone. The team utilised 3D printing technology to design the outer casing, allowing E-Meow to mimic a real pet. Based on the detection from the owner’s environment and actions, it will provide corresponding response. For example, E-Meow can monitor the posture of its owner. When a fall is detected, an alarm will be emitted immediately to inform the bystander, and a distress signal will be sent for help.

Hong Kong Institute of Information Technology at Hong Kong Institute of Vocational Education (Sha Tin)	School	Topic	Abstract
10:00 - 13:30	Ma On Shan Ling Liang Primary School	FlowGuard	Shower water is often unconsciously wasted in daily life. During showers, several litres of water have already flowed away by the time the cold water turns hot. In response to this issue, students designed a water-saving shower head attachment that can be installed on the shower hose, allowing households to save inadequately heated shower water for other purposes. This device uses micro:bit as both a temperature sensor and controller. When the user activates the shower, if the water temperature is below the required standard, the valve will close, redirecting the water to a storage area. Once the temperature reaches the set standard, the valve will open, allowing hot water to flow to the shower. The storage area can be connected to appliances such as washing machines and kitchens, in order to achieve the effect of water conservation.

14:00 - 17:30	LKWFS Lau Tak Yung Memorial Primary School	Hydro Powered Sentinel	In recent years, extreme weather events have become increasingly frequent, leading to sudden and severe flooding in low-lying areas, posing significant threats to both life and property. Providing accurate, reliable, and timely extreme weather forecasts would enable residents to take preventive measures in advance. Operation of the Hydro Powered Sentinel: As water flows through the blades of a generator, the blades rotate, driving the generator. When the flow of water increases, the rotation speed of the blades also rises, resulting in a higher generated current. When the current exceeds a certain amperage, it indicates the occurrence of extreme weather conditions. At this point, the micro:bit will emit a signal to open the sluice gate in the drainage system, increasing water storage capacity, and issue an extreme weather alert to residents in low-lying areas, allowing them to take necessary precautions.
