Passionate Learners, Scientific Inquirers, Responsible Stewards of the Environment


The Singapore Science Curriculum Framework encapsulates the thrust of science education in Singapore to prepare our students to be sufficiently adept as effective citizens, able to function in and contribute to an increasingly technologically-driven world.

All students in Hai Sing Catholic School pursue a four- or five-year course of study in Science. In alignment with the Singapore Science Curriculum Framework, the spirit of scientific enquiry central to our department’s programmes. Together with a passionate heart for learning and a curious mind for inquiring, we hope our students can grow into responsible stewards of the environment.

Special Programs

(1) C.B Paul Science Quiz

Organised by ACJC Science and Maths Council, secondary school students are invited to prove their prowess in the fields of physics, chemistry, biology, mathematics and computer science through a series of tests, for more often than not these questions posed go beyond textbook content.

(2) NYP Science & Technology Challenge

This is an event where students learn to apply science concepts through experimenting. Through experimenting, they learn to try, fail, and try again. The organisers are constantly creating novel tasks each year. Some of the challenges include: to build a bridge that can hold the greatest weight, to design a catapult that can project ping pong balls with accuracy, to create the fastest wind powered vehicle.

(3) East Zone A*STAR Science Fair Competition @ VJC

The East Zone A*STAR Science Fair is held every year to give secondary school students the experience of conducting an investigative science project and provide students with a platform to exhibit and share their findings with others.

(4) Singapore Junior Chemistry Olympiad (SJChO)

The Singapore Junior Chemistry Olympiad (SJChO) provides a platform for all upper secondary students to challenge themselves in their chemical knowledge and skills. It also seeks to promote the excitement in learning and doing Chemistry as well as to identify and develop chemistry talents.
Selected students from Secondary 3 Express students are selected. In Round One, the students will sit for two hour theory paper comprising Multiple Choice Questions. Shortlisted students from Round One will then participate in a Practical component in Round Two.
