Unit
The essential chapter ideas in a clear sequence before practice.
Every measurement identifies a physical quantity, numerical value, unit, and suitable instrument. A value without a unit is incomplete physical information.
Change one independent variable, measure the dependent variable, and control the rest. Repeats improve reliability.
A graph reveals trends and allows slope or intercept analysis. Uncertainty and anomalous points should be discussed, not hidden.
For “Uncertainty”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
For “Graph linearisation”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
For “Experimental design”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
For “Evaluation”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
For “Scientific communication”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
Physics
Follow the method step by step and check why every step is valid.
Length readings are 10.40, 10.60, 10.50 cm. Find the mean and report suitable precision.
Mean ≈ 10.50 cm.
Before calculating, explain the key idea from “Uncertainty” and which conditions must be checked.
The answer should show not only which rule is used for “Uncertainty”, but also why it is valid here.
Experimentieren
Eight graded tasks from core fluency to exam-style application. Work independently before opening a hint or answer.
Readings: 3.0, 3.2, 2.9 cm. Find the mean and half-range uncertainty.
Mean = sum/3; uncertainty = (max-min)/2.
3.033333333333333 cm ≈ 3.03 cm; ±0.15 cm.
Design a valid investigation for “Graph linearisation” with independent, dependent, and 2 controlled variables.
Include range, repeats, and safety.
Full method: clear variables, at least five values, repeats/mean, suitable instruments, 2 controls, and specific safety.
Structure a solution for “Experimental design”: givens, SI units, law, substitution, and interpretation.
State the law before substituting numbers.
A full solution states symbols/units, selects a valid law for “Experimental design”, shows substitution and calculation, and interprets the result.
Identify three uncertainty sources in measuring “Evaluation” and improve each one.
Consider instrument resolution, reaction time, repeats, and controls.
A full response links each specific error source to a targeted improvement and identifies random or systematic impact.
Plan a suitable graph for “Scientific communication” data and explain how to obtain a gradient or relationship.
Put the independent variable on x and dependent variable on y.
A full response labels axes/units, uses a suitable scale and best fit; gradient uses a large triangle and is interpreted with units.
Check whether a result for “Uncertainty” is sensible using units, order of magnitude, and a limiting case.
A check should not merely repeat the same calculation.
A full check confirms dimensions/units, compares expected magnitude, and tests behaviour when one variable becomes very small or large.
Connect “Graph linearisation” to energy conservation or a force/field model and justify the choice.
Define the system and interactions.
A full response defines the system, describes transfer or interaction, applies the appropriate model, and states losses or limitations.
Write a multi-step exam response about “Experimental design” with calculation and evaluation.
Separate givens, model, calculation, result, and evaluation.
A full response includes an appropriate diagram/model, laws, algebraic rearrangement, SI substitution, suitably precise result, and evaluation of assumptions.

A timed, full-mark self-assessment with model-answer guidance.
Start the timer when ready, work without notes, show every step, and open model answers only after finishing.
