Sample Grade 8 General Science Practice Questions

Try these sample questions to review concepts for the Grade 8 General Science exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which of the following represents the correct sequential order of steps in the scientific method?

A.Observation -> Hypothesis -> Experimentation -> Analysis -> Conclusion

B.Hypothesis -> Observation -> Conclusion -> Experimentation -> Analysis

C.Experimentation -> Observation -> Hypothesis -> Analysis -> Conclusion

D.Conclusion -> Hypothesis -> Observation -> Experimentation -> Analysis

Explanation: The scientific method systematically begins with making observations and identifying a problem. A testable hypothesis is then formulated, tested through controlled experimentation, data is analyzed, and finally a valid conclusion is drawn.

2In a scientific investigation, what is the defining characteristic of a scientifically valid hypothesis?

A.It must be an established fact that has already been proven beyond doubt.

B.It must be a testable and falsifiable proposed explanation for an observed phenomenon.

C.It must be a broad mathematical equation accepted by all scientists worldwide.

D.It must be an opinion based solely on personal belief without requiring experimental data.

Explanation: A scientific hypothesis is a tentative explanation for an observation that must be capable of being tested and potentially disproven through controlled experimentation or empirical observation. Without testability, an idea cannot be evaluated scientifically.

3Which of the following contains ONLY fundamental (base) SI quantities?

A.Length, mass, and time

B.Velocity, acceleration, and force

C.Area, volume, and density

D.Energy, power, and electric current

Explanation: Length, mass, and time are three of the seven base SI physical quantities defined independently of other quantities. Their base SI units are the metre (m), kilogram (kg), and second (s).

4What is the standard International System of Units (SI) base unit for measuring thermodynamic temperature?

A.Degree Celsius (°C)

B.Degree Fahrenheit (°F)

C.Kelvin (K)

D.Joule (J)

Explanation: The Kelvin (K) is the coherent SI base unit of thermodynamic temperature. Although Celsius is widely used in everyday situations, Kelvin is the international scientific standard starting at absolute zero.

5Density is defined as mass per unit volume. What is the coherent SI derived unit of density?

A.g/cm³

B.kg/m³

C.kg/L

D.N/m²

Explanation: Because the SI base unit for mass is the kilogram (kg) and for volume is the cubic metre (m³), the coherent SI derived unit for density (mass divided by volume) is kilogram per cubic metre (kg/m³).

6A student needs to accurately measure the internal diameter and depth of a narrow cylindrical test tube. Which laboratory instrument is best suited for this measurement?

A.Metre rule

B.Measuring tape

C.Beam balance

D.Vernier caliper

Explanation: A Vernier caliper has external jaws, internal upper jaws, and a depth probe, allowing high-precision measurement of internal diameters, external diameters, and depths up to 0.1 mm or 0.05 mm accuracy.

7When measuring the volume of water using a graduated glass cylinder, how should a student read the liquid level to avoid error?

A.Read the top edge of the curved water surface from an angle above the cylinder.

B.Position the eye level with the bottom of the concave meniscus.

C.Position the eye level with the top of the convex meniscus.

D.Read the average between the highest and lowest points while holding the cylinder tilted.

Explanation: Water adheres to glass, forming a curved concave surface called a meniscus. Accurate volume reading requires positioning the eye horizontally level with the lowest point of the concave meniscus to prevent parallax error.

8Which statement correctly distinguishes a beam balance from a spring balance?

A.A beam balance measures mass by comparing against standard masses, whereas a spring balance measures weight using the extension of a spring.

B.A beam balance measures gravitational weight in newtons, whereas a spring balance measures mass in kilograms.

C.A beam balance changes its reading depending on the local gravitational field strength, whereas a spring balance remains constant everywhere.

D.Both balances measure volume directly by liquid displacement.

Explanation: A beam balance compares an unknown mass to known reference masses and measures mass independent of local gravity. A spring balance measures downward gravitational force (weight) based on Hooke's law of spring extension.

9In traditional Ethiopian communities, traditional units such as the 'sinzar' (span) and 'kend' (cubit) have been used for measuring length. Why were these traditional units replaced by standard SI units in scientific work?

A.Traditional units were too difficult to pronounce in scientific laboratories.

B.Traditional units vary from person to person and lack reproducibility and standardization.

C.Traditional units were based on decimal powers of ten that caused calculation errors.

D.Traditional units could only measure liquids and could not measure solid objects.

Explanation: Traditional body-based units like the sinzar (hand span) or kend (forearm length) vary according to an individual's body size. Scientific investigations require standardized, universally reproducible units like the metre so measurements are consistent worldwide.

10When diluting concentrated sulfuric acid with water in a school laboratory, which safety procedure must always be followed?

A.Quickly pour water into the concentrated acid while shaking vigorously without goggles.

B.Add both water and concentrated acid simultaneously into a sealed glass flask.

C.Slowly add the concentrated acid to water with continuous gentle stirring.

D.Heat the acid to boiling before adding cold water directly into the container.

Explanation: The dissolution of concentrated acid in water is highly exothermic. Adding acid slowly to a large volume of water allows the water to absorb the heat safely. Adding water to acid can cause rapid boiling and explosive splattering of corrosive acid.

About the Grade 8 General Science Exam

The Ethiopia Grade 8 Middle School Examination for General Science is an integrated science paper administered at the end of Grade 8 by Regional Education Bureaus (REBs) and chartered city administrations. Standards and competency benchmarks are centrally set by the FDRE Ministry of Education under the General Education Curriculum Framework (GECF Table 3, Subject 5). General Science is examined as a single integrated paper combining biology, chemistry, and physics at middle-school depth rather than three separate disciplines. Passing Grade 8 leads to the Middle School Education Certificate and qualifies students for progression into Grade 9 secondary school, where science branches into separate biology, chemistry, and physics subjects. This bank is an English-language MCQ study adaptation aligned with the MoE Grade 7 and Grade 8 General Science syllabi.

National learning competencies and curriculum standards are set by the FDRE Ministry of Education (MoE). The examination papers are prepared, scheduled, administered, and certified by the Regional Education Bureaus and chartered city administrations.

How does middle-school General Science relate to secondary education?

Grade 8 General Science provides the foundational knowledge for Grade 9, where general science splits into dedicated subject courses: Biology, Chemistry, and Physics.

What certificate is awarded upon passing the Grade 8 exam?

Candidates receive the Middle School Education Certificate (Grades 7–8), which is the official credential for entry into general secondary education (Grades 9–12).
