H2 Physics Paper 4 Technique File: What to Keep From Every Practical
A H2 Physics 9478 Paper 4 technique-file guide for turning lab worksheets into reusable notes on measurement, graphs, uncertainty, planning, and apparatus.
The core idea is simple: A technique file turns each practical into reusable exam habits.
Use it as a working check: Keep setup, measurement, graph, uncertainty, planning, and ACE notes for every investigation.
Then go one layer deeper: After each lab, write the fault you met, the fix that worked, and the sentence you would use in Paper 4.
H2 Physics Paper 4 is not revised well by rereading old worksheets. The useful version is a technique file: a small set of notes that records what the apparatus did, how the data was processed, and how you would write the answer under exam timing.
Use the H2 Physics practical lab mastery guide for the full Paper 4 map. Use this page to build the file you keep beside every practical.
The five-page technique file
| Page | What to keep | Why it matters |
| Apparatus families | Circuit, mechanics, waves, thermal, field, and sensor setups | Paper 4 often tests recovery when a setup is unfamiliar |
| Measurement habits | Zero error, repeats, range, resolution, and alignment | MMO marks depend on controlled measurement |
| Graph and spreadsheet routes | Axis choice, linearisation, gradient, intercept, residuals | PDO and ACE depend on data treatment |
| Uncertainty language | Dominant uncertainty, percentage uncertainty, direction of error | Evaluation must name the effect, not just the problem |
Practical course completion-record note
For practical, lab, and experiment courses, Eclat Institute maintains centre-held attendance records and may also issue an internal attendance or completion document based on participation and internal assessment.
- For SEAB private-candidate declarations, the key evidence is the centre's attendance or completion record, not a government-issued certificate.
- This is an internal centre-issued certificate, not an MOE/SEAB qualification or accreditation.
- Recognition (if any) is determined by the receiving school, institution, or employer.
- For SEAB private candidates taking science practical papers, SEAB states you should either have taken the subject before or attend a practical course and complete it before the practical paper date.
