Connect particle motion and interaction with pressure, temperature, and changes of state. The model should explain the observation.
Temperature is not the same as total thermal energy. Mass, material, and temperature change affect transferred energy.
Thermal energy transfers because of a temperature difference. Identify conduction, convection, or radiation and justify the dominant mechanism.
For “Density”, 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 “Gas pressure”, 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 “Changes of state”, 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 “Internal energy in simple terms”, 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 “Solar system”, 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.

How much energy raises 0.3 kg of water by 30 °C? c = 4200 J/(kg·°C).
Q = 37800 J
Before calculating, explain the key idea from “Density” and which conditions must be checked.
The answer should show not only which rule is used for “Density”, but also why it is valid here.

0.7 kg of water warms by 25 °C; c=4200 J/(kg·°C). Find Q.
Q=mcΔT.
Q=73500 J.
Structure a solution for “Gas pressure”: givens, SI units, law, substitution, and interpretation.
State the law before substituting numbers.
A full solution states symbols/units, selects a valid law for “Gas pressure”, shows substitution and calculation, and interprets the result.
Identify three uncertainty sources in measuring “Changes of state” 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 “Internal energy in simple terms” 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 “Solar system” 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 “Gravity” 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 “Orbits” 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.
Compare two methods for investigating “Stars introduction” and select the more reliable using criteria.
Use accuracy, repeatability, control, and safety.
The choice must use at least three comparable criteria and acknowledge one trade-off or limitation.

Physics
KS3 Year 8: структурований маршрут з математики та фізики з розділами, практикою і наступними кроками.
Структура відповідає підручнику й допомагає організувати вивчення теми.
Теми, де найчастіше виникають помилки або потрібна додаткова практика.
З чого почати: підручник, daily material, PDFs, videos і worked examples.
Цільова практика перед full tests, щоб coverage було зрозумілим.
Як вимірювати прогрес у главі і коли додавати її до загального mock.
Що робити після глави і як вона пов'язана з наступним розділом.
Примітка: офіційну екзаменаційну програму кожного року завжди уточнюйте у школі, викладача та за поточними офіційними джерелами.
