Practise the set-up, measurement, graphing, and evaluation habits behind common Year 3 and Year 4 IP Physics practicals.
Last updated: 2026-07-10
Student stage
Year 3 to Year 4
Guided lab
1.5 hours
Mock format
50 min lab + 10 min review
It does not replace the broader IP Physics tuition page, which covers theory and school sequence. It focuses on apparatus, readings, tables, graphs, uncertainty, and practical WA performance.
Practical coverage is matched to the student's school, year, current topic, and assessment notice. IP school sequences are not identical, so these topic families describe the planned scope, not a fixed national Year 1 to Year 4 syllabus.
The chosen experiment should match the student's current school topic or the practical notice issued for the next WA.
Converging lenses, focal length, ray alignment, prisms, refraction, and recording repeatable image or angle measurements.
Build circuits safely, use variable resistance, rheostats or sensors, measure potential difference and current, and interpret relationships.
Use Hooke's law, pendulum timing, repeated readings, gradients, and decisions about the useful range of data.
Work with heating, cooling, boiling water or ice, and energy measurements while controlling heat loss and timing consistently.
Guided lab - 1.5 hours
The tutor can pause at the set-up, observation, table, graph, or explanation stage to repair the exact habit that is weak. This fits a student who needs instruction and repetition.
Practical mock - 1 hour
The planned format uses 50 minutes for the practical and 10 minutes for questions, marking, and immediate feedback. This fits a student who already knows the method but needs timed WA practice.
A practical WA can test both hands-on work and the thinking that follows it. The transferable target is a complete evidence chain: make a fair measurement, record it clearly, present the pattern, and explain what the evidence supports.
Choose and handle apparatus safely, then control the important variables.
Separate observations from inferences and use tables with units and sensible precision.
Choose graph axes and scales that reveal the relationship without distorting the data.
Use the result to answer theory questions, evaluate the method, and suggest a workable improvement.
Each page has one job. Use the broad overview when the need is still unclear, then move to the lower-secondary or subject page when the student's level and practical family are known.
Start with the broad programme map, then choose the page that matches the student's level and subject.

Open this routeUse this when the immediate need is a timed rehearsal rather than a topic lesson.
Open this routeUsually not. Apparatus fluency improves through focused repetition. Start with the upcoming WA family or the clearest weakness, such as circuit set-up, lens alignment, graphing, or evaluation.
The student should be able to record consistent readings, include units and sensible precision, plot a useful graph, interpret the relationship, and discuss limitations using the actual set-up.
No. IP schools can sequence topics and internal assessments differently. These pages describe useful practical families and transferable lab skills, not a promise that every school will run the same experiment in the same term.
Share the student's school, year, subject, upcoming WA date, and any practical notice or worksheet the school has issued. That lets us check whether the planned lab is a useful match.
For practical, lab, and experiment courses, Eclat Institute keeps centre-held attendance records and may also issue an internal attendance or completion document based on participation and internal assessment.
