练习前按清晰顺序掌握本章核心概念。
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 “Φυσικά μεγέθη”, 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 “Μονάδες μέτρησης”, 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 “Μετατροπές μονάδων”, 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 “Πίνακες και γραφήματα”, 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 “Φυσικά μεγέθη”, the first condition gives 9 units and the second 6. 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 “Φυσικά μεγέθη” 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.

八道分层练习，从基础熟练到考试应用。请先独立完成，再查看提示或答案。
Record 4 safe observations about “Φυσικά μεγέθη” without writing a conclusion yet.
An observation is something seen, heard, or measured.
The response needs 4 specific observable or measurable statements, not guesses about cause.
Design a fair test for “Μονάδες μέτρησης”: what changes, what is measured, and which 4 things stay the same?
Change one factor only.
Full response: one changed factor, one measurable outcome, and 4 controlled conditions.
Measurements are 3, 6, 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 3, difference 6 units.
Sort examples of “Πίνακες και γραφήματα” 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 “Φυσικά μεγέθη”.
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 5, 7, 9, predict the next value and explain the pattern.
Look for the constant change +2.
11; +2.
Write 4 safety rules for a simple activity about “Μετατροπές μονάδων” and explain the risk each reduces.
Link each rule to a reason.
A full response gives 4 specific rules, each linked to a risk, and requires supervision where appropriate.
Data A=4 and B=10. Write a conclusion, evidence, and one limitation about “Πίνακες και γραφήματα”.
Do not claim more than the two values show.
B is 6 greater than A. The values support this, but two measurements alone do not prove a general rule.

六道不同作业，从基础到挑战，包含预计用时、提示和答案指南。
Homework 1: Record 7 safe observations about “Φυσικά μεγέθη” without writing a conclusion yet.
An observation is something seen, heard, or measured.
The response needs 7 specific observable or measurable statements, not guesses about cause.
Homework 2: Design a fair test for “Μονάδες μέτρησης”: 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.
Homework 3: Measurements are 6, 2, and 8 units. Put them in a table, find the greatest, and the difference from the least.
Use condition and measurement headings.
Greatest 8, least 2, difference 6 units.
Homework 4: Sort examples of “Πίνακες και γραφήματα” 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.

The quantity, instrument, and unit must match, e.g. time-stopwatch-s or length-ruler-cm.
Homework 6: From data 8, 11, 14, predict the next value and explain the pattern.
Look for the constant change +3.
17; +3.
