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 “διαφορά εννοιών”, 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 “θερμική ισορροπία”, 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 “μέτρηση”, 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 “διαφορά εννοιών”, 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 “διαφορά εννοιών” 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.
Θερμοκρασία και θερμότητα
Вісім завдань від базових навичок до екзаменаційного рівня. Спочатку виконайте самостійно.
Record 9 safe observations about “διαφορά εννοιών” 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 “θερμική ισορροπία”: what changes, what is measured, and which 2 things stay the same?
Change one factor only.
Full response: one changed factor, one measurable outcome, and 2 controlled conditions.
Measurements are 8, 4, and 12 units. Put them in a table, find the greatest, and the difference from the least.
Use condition and measurement headings.
Greatest 12, least 4, difference 8 units.
Sort examples of “διαφορά εννοιών” 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 “θερμική ισορροπία”.
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, 8, 13, predict the next value and explain the pattern.
Look for the constant change +5.
18; +5.
Write 2 safety rules for a simple activity about “διαφορά εννοιών” and explain the risk each reduces.
Link each rule to a reason.
A full response gives 2 specific rules, each linked to a risk, and requires supervision where appropriate.
Data A=9 and B=13. Write a conclusion, evidence, and one limitation about “θερμική ισορροπία”.
Do not claim more than the two values show.
B is 4 greater than A. The values support this, but two measurements alone do not prove a general rule.
Θερμοκρασία και θερμότητα
Шість різних завдань від базового рівня до складного з часом, підказками та відповідями.
Homework 1: Record 5 safe observations about “διαφορά εννοιών” 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 “θερμική ισορροπία”: what changes, what is measured, and which 3 things stay the same?
Change one factor only.
Full response: one changed factor, one measurable outcome, and 3 controlled conditions.
Homework 3: Measurements are 4, 5, and 9 units. Put them in a table, find the greatest, and the difference from the least.
Use condition and measurement headings.
Greatest 9, least 4, difference 5 units.
Homework 4: Sort examples of “διαφορά εννοιών” 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.
Homework 5: Choose a suitable tool and unit to measure something connected with “θερμική ισορροπία”.
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.
Homework 6: From data 6, 12, 18, predict the next value and explain the pattern.
Look for the constant change +6.
24; +6.
