Introduction
This examination assesses foundational knowledge and applied understanding of introductory science concepts. It
evaluates skills in scientific inquiry, measurement, matter, energy, force, motion, living organisms, Earth and space
science, and laboratory safety. Questions include multiple-choice and scenario-based formats designed to test real-
,world application, critical thinking, and decision-making. The exam emphasizes regulatory compliance, ethical
standards, and professional practice. Candidates are expected to demonstrate mastery of core principles and the ability
to apply them in practical, professional, and everyday contexts. This assessment prepares learners for advanced study
and informed participation in a scientifically literate society.
SECTION ONE: QUESTIONS 1–50
1. Which step of the scientific method involves developing a testable prediction?
A. Observation
B. Hypothesis
C. Experiment
D. Conclusion
🟢 Correct Answer: B. Hypothesis
🔴 Explanation: A hypothesis is a testable prediction based on observations and prior knowledge, forming the basis
for experimentation.
2. What is the SI unit for measuring length?
A. Kilogram
B. Second
,C. Meter
D. Liter
🟢 Correct Answer: C. Meter
🔴 Explanation: The meter is the base SI unit for length, used internationally in scientific measurement.
3. A student records the volume of water in a graduated cylinder as 45.0 mL. Which characteristic of
measurement does the ".0" represent?
A. Accuracy
B. Precision
C. Uncertainty
D. Error
🟢 Correct Answer: B. Precision
🔴 Explanation: The decimal place indicates the precision of the measurement, showing the instrument's smallest
calibrated increment.
4. Which state of matter has a definite volume but no definite shape?
, A. Solid
B. Liquid
C. Gas
D. Plasma
🟢 Correct Answer: B. Liquid
🔴 Explanation: Liquids have definite volume because particles are close together but no definite shape because
particles flow to fit the container.
5. What type of energy is stored in a stretched rubber band?
A. Kinetic energy
B. Thermal energy
C. Potential energy
D. Nuclear energy
🟢 Correct Answer: C. Potential energy
🔴 Explanation: Elastic potential energy is stored when an object is stretched or compressed and is released when
the object returns to its original shape.
6. Which of Newton's laws explains why a passenger continues moving forward when a car suddenly stops?
