Build the Year 1 and Year 2 lab habits that sit underneath later Physics, Chemistry, and Biology practicals: safe handling, useful observations, clean data, graphs, and short evidence-based explanations.

Student stage
Year 1 to Year 2
Guided lab
1.5 hours
Mock format
50 min lab + 10 min review
At lower secondary, students are often learning science through an integrated or combined programme. The important search need is therefore the stage and the practical skill, not three thin subject pages with nearly identical beginner content.
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.
These are useful families drawn from the programme brief. They are examples for matching a student's need, not a universal IP school syllabus.
Filtration, chromatography, choosing suitable apparatus, and explaining why each separation step works.
Record changes carefully, distinguish observation from explanation, and connect visible evidence to the reaction being studied.
Use the correct test and record the positive result precisely instead of writing a vague colour or sound description.
Set up data tables, choose units and graph scales, identify variables, and answer theory or open-ended questions from the evidence collected.
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 routeNot always. Schools use different programme names and sequences. This page uses combined science as a simple description of the Year 1 to Year 2 stage where practical foundations can span Physics, Chemistry, and Biology.
The experiment may be simple, but marks can depend on precise observations, a correctly structured table, sensible graph scales, controlled variables, and a short explanation that uses the student's own evidence.
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.
