Practise common Year 3 and Year 4 IP Chemistry experiments with guidance, then try the technique, observations, calculations, and evaluation under time pressure.

Student stage
Year 3 to Year 4
Guided lab
1.5 hours
Mock format
50 min lab + 10 min review
It focuses on practical technique and evidence. The broader IP Chemistry tuition page remains the route for ongoing theory, school-sequence, and written-paper support.
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 programme brief emphasises frequently reused O-Level-style lab families. The precise method, chemicals, and assessment format can still vary by school.
Use burette and pipette technique, phenolphthalein or methyl orange, repeat titres, a clear results table, and linked calculations.
Test unknown salts systematically, separate test from result, and record precipitates, gases, and changes with precise language.
Connect colour or temperature changes to the chemistry, control quantities, and explain energy evidence rather than only naming the topic.
Measure gas volume, use a gas syringe, or time an obscured-mark reaction while keeping variables and the endpoint consistent.
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.
Send us the student's school, year, subject, next assessment date, and any instructions from the school. We will recommend the session, time, and place that fit best.
Guided labs and timed mocks usually run in groups. WhatsApp opens a private chat, but that does not mean the session is automatically one-to-one. We will confirm the group size before you book.
These are two-hour windows when the lab is available. A one-hour mock or 1.5-hour guided lab uses part of that time. We will confirm the exact start and end time before you book.
Timings last updated: 17 July 2026.
The place depends on the subject, equipment, and available group.
A full practical lab for Chemistry, Physics, and Biology, not an ordinary classroom.
IP guided labs and practical mocks are shorter than our two-hour O-Level and H2 practical clinics. We will confirm the current IP price before you book.
We will also put the topic, equipment, tutor, place, duration, group size, and price in writing. We do not promise a particular grade.
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.
These routes support the practical page without duplicating its job. Use notes for concept review, tuition for ongoing school support, and later practical hubs for the JC progression.
The student should know common test logic and observation language, but still record what actually happens. A memorised answer that contradicts the experiment is not useful evidence.
Technique, initial and final readings, precision, repeat titres, table structure, and calculation working can all matter. The final concentration alone does not show whether the method was reliable.
No. Each IP school can teach topics and run assessments in a different order. These pages cover common types of practical work and the lab skills that carry across schools.
Send the student's school, year, subject, next assessment date, and any instructions or worksheet from the school. We can then check which session fits.
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.
