Charge is a property, current is charge flow rate, and potential difference is energy per unit charge. Keep these definitions distinct.
Draw a closed circuit with correct symbols. Apply charge conservation at junctions and energy conservation around loops where required.
Field lines indicate direction and relative strength. In induction, changing magnetic flux is linked to induced potential difference.
For “μαγνητικά υλικά”, 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 “πόλοι”, 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 “δοκιμή και ταξινόμηση”, 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.

In a safe test about “μαγνητικά υλικά”, the first condition gives 14 units and the second 11. Which is greater, and what should be kept the same?
The first value is greater by 3 units. A fair test changes only one factor.
Explain “μαγνητικά υλικά” in your own words and use a picture, objects, a table, or a simple measurement to support it.
A complete explanation connects the correct idea, a clear representation, and a sensible check.

Вісім завдань від базових навичок до екзаменаційного рівня. Спочатку виконайте самостійно.
Record 9 safe observations about “μαγνητικά υλικά” without writing a conclusion yet.
An observation is something seen, heard, or measured.
The response needs 9 specific observable or measurable statements, not guesses about cause.
Design a fair test for “πόλοι”: what changes, what is measured, and which 5 things stay the same?
Change one factor only.
Full response: one changed factor, one measurable outcome, and 5 controlled conditions.
Measurements are 8, 2, and 10 units. Put them in a table, find the greatest, and the difference from the least.
Use condition and measurement headings.
Greatest 10, least 2, difference 8 units.
Sort examples of “μαγνητικά υλικά” into two groups and state the sorting rule.
Each item should clearly match one group.
A full response gives two named groups, at least two examples in each, and an observable sorting rule.
Choose a suitable tool and unit to measure something connected with “πόλοι”.
Decide whether you measure length, time, mass, temperature, or volume.
The quantity, instrument, and unit must match, e.g. time-stopwatch-s or length-ruler-cm.
From data 3, 6, 9, predict the next value and explain the pattern.
Look for the constant change +3.
12; +3.
Write 5 safety rules for a simple activity about “μαγνητικά υλικά” and explain the risk each reduces.
Link each rule to a reason.
A full response gives 5 specific rules, each linked to a risk, and requires supervision where appropriate.
Data A=9 and B=11. Write a conclusion, evidence, and one limitation about “πόλοι”.
Do not claim more than the two values show.
B is 2 greater than A. The values support this, but two measurements alone do not prove a general rule.

Homework 1: Record 5 safe observations about “μαγνητικά υλικά” without writing a conclusion yet.
An observation is something seen, heard, or measured.
The response needs 5 specific observable or measurable statements, not guesses about cause.
Homework 2: Design a fair test for “πόλοι”: what changes, what is measured, and which 6 things stay the same?
Change one factor only.
Full response: one changed factor, one measurable outcome, and 6 controlled conditions.
Homework 3: Measurements are 4, 3, and 7 units. Put them in a table, find the greatest, and the difference from the least.

Greek Primary Grade 2: 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.
