Last updated on 10 November 2026

The Nan Hua Science department recognises that our students are diverse, with different needs, interests and aptitudes for Science. Given the diversity of our students and our commitment to nurture future ready students, the Science department is aligned with the twin goals of Science education in Singapore which is to

  • enthuse and nurture all students to be scientifically literate, so that they are able to make informed decisions and take responsible actions in their daily lives; and

  • provide strong Science fundamentals for students to innovate and pursue STEM for future learning and work.

The department endeavours to strengthen the enactment of the Secondary Science curriculum through the Science Curriculum Framework and STEM learning, with a focus on developing emerging 21st century competencies (e21CC), Digital Literarcy and Technological Skills (DLTS) and AI literacy. We strive to provide varied learning experiences to our students to achieve the goals mentioned above.

STEM Endeavours

Echoing the nation’s call for promoting STEM education in Science teaching, the department continues to weave in STEM related activities and experiences in the curriculum and at the same time strongly encourage all our students to participate in the STEM challenges organised nationally by MOE (CPDD) and the Science Centre. The aim of the STEM challenges is to encourage and develop students’ interest, curiosity, and creativity. To enable this, opportunities were created for all students to participate in the challenge during curriculum time. As students immerse in the world of discovery, they demonstrated their creativity and critical thinking while igniting a passion for scientific exploration. Students had the chance to turn everyday things into extraordinary creations. They got to experiment with their ideas to continually enhance them, which is the spirit and essence of STEM!

Our school is proud to have clinched 1st Place nationally for the 2026 STEM Challenge and this is the third consecutive year we have done it.

Sec 3 Life Science workshop

The Science department conducts an in-house Life Science workshop for our Sec 3 students every year. This year, in this hands-on workshop on Infectious Diseases, students dive into microbiology and immunology by culturing bacteria from their own environment and testing the efficacy of natural and artificial antibiotics. By observing zones of inhibition, the clear areas on agar plates where bacterial growth is prevented, students discovered how antimicrobial agents work. The students also get to learn about ELISA (Enzyme-Linked Immunosorbent Assay), how this standard laboratory test detects proteins, antibodies, and antigens, underscored by its real-world application as an antibody test during the COVID-19 pandemic.

2026 Singapore Junior Biology Olympiad (SJPO)

The Singapore Junior Biology Olympiad (SJBO) provides a valuable platform for upper secondary students to deepen their understanding of biology and challenge themselves beyond the school curriculum. Through tackling challenging questions that require a strong grasp of biological fundamentals, students develop critical thinking, analytical and problem-solving skills. Participating in the competition also encourages intellectual curiosity, independent learning and perseverance, while allowing students to apply their knowledge in unfamiliar contexts and discover a greater appreciation for the fascinating world of biology.

2026 Singapore Junior Chemistry Olympiad (SJChO)

Four students represented the school at the Singapore Junior Chemistry Olympiad (SJChO), a prestigious national competition that challenges upper secondary students to apply their chemical knowledge and demonstrate strong problem-solving skills. By advancing to Round 2, they showcased their intellectual curiosity, perseverance and commitment to academic excellence.

The SJChO offers students a valuable opportunity to extend their learning beyond the classroom, challenge themselves alongside peers from across Singapore, and deepen their passion for chemistry through a rigorous and rewarding competitive experience.

2026 Singapore Junior Physics Olympiad (SJPO)

The Singapore Junior Physics Olympiad (SJPO) is a prestigious national competition that challenges secondary school students to apply their understanding of Physics to complex and thought-provoking problems. This year, 15 of our students demonstrated strong analytical and problem-solving skills, and three of them earned well-deserved recognition for their efforts.
