Complete Guide to Junior Secondary Physics in Hong Kong
TUTORZONE SUBJECT GUIDE · LOCAL SECONDARY SCHOOL
Physics tuition, curriculum overview, key concepts, assessment & STEM integration — a complete guide to Hong Kong’s S1–S3 Physics, from the seven core units and their experiments through to assessment weighting and at-home support.
Direct Answer：What is Junior Secondary Physics in Hong Kong?
Junior Secondary Physics (S1–S3) in Hong Kong covers seven core units with experiments, assessment weighting, and STEM integration.
What Is Junior Secondary Physics?
Junior Secondary Physics (S1–S3) in Hong Kong introduces students to scientific thinking through the “Observe–Model–Verify” method. The curriculum aims to cultivate students’ physical intuition, logical reasoning, and hands-on experimental skills — laying a strong foundation for future STEM education and HKDSE Physics.
As an essential part of Hong Kong’s science education, the course aims to:
- Build core physics concepts——from natural phenomena
- Enhance inquiry and experimentation——through lab work
- Develop real-world problem-solving skills
- Prepare students for HKDSE Physics——and other science subjects

Frequently Asked Questions (FAQ)
Q: Is Junior Secondary Physics difficult for most students?
It builds upward from concrete, everyday phenomena to abstract models, so most students find it manageable with steady practice — the heavy emphasis on hands-on experiments turns abstract ideas into something visible and testable.
Q: How can I help my child prepare for HKDSE Physics?
Encourage consistent lab-report habits and curiosity about everyday physics. The junior curriculum already introduces vectors and foundational calculus concepts in S3, which form the bridge to senior Physics.
Q: What equipment do we need for at-home experiments?
Very little — most experiments reuse household items. A smartphone can measure gravitational acceleration, and kitchen tools can compare heat conduction; for structured work, hands-on kits such as mechanics car sets and optics experiment kits are widely available.
Q: How is the subject assessed?
Assessment is split between school-based work (60%) — lab reports and STEM projects — and a public assessment (40%) made up of multiple-choice, calculation, and essay questions.
