25th Primary STEM Project Exhibition (PSPE)

You or your representatives are cordially invited to cover the 25th Primary STEM Project Exhibition (PSPE) on 11 May (Thursday). It will be held in-person for the first time in three years. 


The exhibition is co-organised by the Centre for Environment and Sustainable Development (CESD) and the Department of Science and Environmental Studies at The Education University of Hong Kong (EdUHK), along with other parties.


As the largest annual exhibition on STEM education in Hong Kong, PSPE enables primary students to integrate their subject knowledge and STEM skills in exploring different topics. Themed “Water and Sustainable Development”, this year’s exhibition will showcase nearly 150 STEM projects on water management developed by teams from local schools and schools in the Greater Bay Area. It includes: 


  • Conducting water quality tests for the Ng Tung River, and exploring means of filtration and purification to improve the living environment of aquatic life;
  • Applying the concept of ‘Sponge City’ to transform facilities in school;
  • Making a ‘cooling house’ which draws filtrated sewage to the roof for the purpose of cooling;
  • Exploring the possibility of generating water from air to create a water-generating device that can be utilised both at home and in the ocean;  
  • Building a coral-growing base to securely hold broken corals in place
