O-Level Physics Home Lab Apparatus Checklist
Study guide
TL;DR
SEAB’s 2026 O-Level Physics syllabus lists 18 typical Paper 3 practical techniques in its Paper 3 section.
You can rehearse most of them at home with safe, low-cost substitutes - but keep to school-grade apparatus for final calibration.
Log sources, costs, and limitations so ACE commentary remains realistic.
Pair this checklist with the full practical roadmap in our O-Level Physics Experiments hub.
1 | Priority apparatus by experiment family
| Practical | School apparatus | Home/affordable substitute | Notes & limitations |
| Length/diameter | Metre rule, vernier calipers, micrometers | Metal rulers with 0.5 mm markings, digital calipers (around $20) | Calibrate against a reliable reference (coin, calibration strip). |
| Time | Digital stopwatch | Smartphone stopwatch / PhyPhox timer | Reaction time still affects accuracy - practise multi-period timing. |
| Density | Electronic balance, measuring cylinder | Kitchen scale (0.1 g), 100 mL syringe or measuring jug | Expect larger uncertainty; dry objects thoroughly before measuring. |
| g measurement |

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.
