Let's take a look at some of our Tier 1 programmes

ALP 1.png

The Waste Management module is conducted for Secondary 1 Express, Normal Academic and Normal Technical students over one semester during their Science lessons.

In this module, students learn about the importance of eco-sustainability and develop an awareness about waste management related issues in Singapore and around the world.

Our students also learn about the design and construction of a vermicomposting system as a method of food waste recycling in their vermicomposting module. In groups, they identify matured vermicompost in the form of worm casts and assess the results of the compost through a simple bioassay. Students also test for the presence of the NPK (nitrogen, phosphorous and potassium) elements which are essential for plant growth through colourimetric tests.

Our Achievements


2017 Shell Bright Ideas Challenge
Teachers ICs: Mr Jonathan Ng & Mr Freddy Wong, guided by STEM educator, Ms Iris Ng
Achievement - Merit Award & Young Engineer Gold Award


The Bright Ideas Challenge is a national challenge which provides a platform for secondary students to imagine creative ideas of how cities of the future might be powered. It provides an opportunity for students to see how STEM can tackle real world problems and make a positive difference in the world. It is designed to spark young people’s curiosity in STEM and to inspire the next generation of scientists, engineers and innovators.

Team Hydronyamz comprising of Aimery Tay, Oliver Ong, Vernice Long from Class 3A and Ryan Neo, Joyce Ngiam from Class 3B took part in the Shell Bright Ideas Challenge 2017. The team’s task was to tackle the energy shortage that the world may face in 2050. The team was guided by Mr Jonathon Ng, Mr Freddy Wong and Ms Iris Ng who is our STEM educator. 

Putting on their thinking caps, the students identified a possibility of water shortage and an increasing competition for land usage. These factors could create pressure on households to minimise their water wastage. The team researched on the water wastage across various household appliance and created a prototype that could collect used water from household appliance like washing machines and air conditioners. The water will be filtered and collected at a common collection point. If needed, the water will be channelled back to the appliances.



The team was shortlisted as one of the fifteen finalists to present their idea to a panel of judges as well as the public. The students were also given the opportunity to present and converse with the Education Minister, Mr Ng Chee Meng.



We are proud to announce that they received the Merit Award for their prototype and all five students also achieved the Young Engineer Gold Award.

Our students have been featured in the above video from 2.17 to 2.30, titled, 
Science Centre The Bright Ideas Challenge 2017.

2017 Elementz Science Project Competition (Lower Secondary)
Teachers ICs: Ms Debbie Teo, Ms Christine Hor & Mr Roy Tan
Achievement – Gold Award & Certificate of Commendation


Punggol Secondary School participated in the 17th Elementz Science Project Competition & Exhibition organised by Anderson Secondary School. This competition requires students to undertake an investigative-type project. This allows students to experience conducting their own experiments, write report based on their findings and lastly to share their projects in front of a panel of judges. Two Secondary 2 teams participated and we are proud to announce that we clinched a Gold and a Certificate of Commendation. 

8 students from Secondary 2 started their journey at the end of May where they came together in their teams to decide on the projects they would like to embark. From their exposure to vermicomposting and biocompost during their Applied Learning Programme in Secondary One, the two teams decided to research on the red wrigglers’ (Eisenia foetida) diet on the potency of worm cast as fertilisers and the effect of the application method of organic compost on plant growth. 


Two months of hard work culminated in some interesting findings such as apple peels giving the most effective compost and spraying nutrient solution likely gave the best growing plant. The students presented these ideas via a 10 minute presentation at Anderson Secondary School. Participating in this competition has exposed the students to the scientific methodology and they picked up new skills like critical thinking, report writing, data analysis and oral presentation. They have also learned to persevere through difficulties and the teams came out stronger than before. 


2018 Elementz Science Project Competition (Lower Secondary)
Teachers ICs: Ms Debbie Teo & Ms Christine Hor
Achievement – Top Viewer's Choice, Gold Award & Certificate of Commendation

This year, we sent another two teams to participate in this competition. The teams worked tirelessly over the past four months and through the June holidays and emerged victorious as they managed to clinch a Gold and a Certificate of Commendation for their projects. We were also pleasantly surprised when we were presented with the top Viewers’ Choice award for the Gold award project.  

The theme for this year’s competition was “Changing the World, One Idea at a Time”. After cycles of brainstorming, the teams decided to investigate on the use of starch-based bioplastics and pervious concrete. The project involves three phases: experimentation, report writing and presentation. Although the teams faced some difficulties during the experimentation process, they did not give up and exhibited resilience as they continued to find solutions. Through the entire process, the students also learned scientific methods and skills to write a science report as well as presentation skills. At the same time, they learned to communicate and worked well with one another as a group. Congratulations to both groups once again!
