QUESTIONS AND ANSWERS TEST BANK FOR
2026.
⫸ What is a scientific theory, and what are its key characteristics?
Answer: A scientific theory is a broad generalization that explains a
body of facts or phenomena. Key characteristics of a scientific theory
include:
- It is capable of being tested by multiple independent researchers.
- It provides well-established and highly reliable explanations.
- It explains a greater number of observations in more general terms.
- As scientific knowledge evolves, discarded theories can still provide
insight into scientific happenings.
⫸ What is the role of a variable in a controlled experiment? Answer:
The scientist chooses one variable to observe and measure the
outcome of the change.
⫸ Do all experiments include a control group? Answer: No, not all
experiments have control groups.
⫸ What is a constant in a controlled experiment? Answer: A
constant is the variable that is kept the same throughout the
experiment.
,⫸ What is the purpose of a control group in an experiment? Answer:
The control group remains normal or untreated during the experiment
to serve as a baseline for comparison.
⫸ Steps of Inquiry Based Approach Answer: 1. Making
Observations
2. Generating Questions
3. Investigating & Gathering Evidence
4. Conclusion
5. Discussion
⫸ What are the steps of the scientific method? Answer: 1. Generate
question
2. Formulate Hypothesis
3. Test Prediction
4. Refine, reject, or expand on hypothesis
5. Communicate Findings
⫸ Inquiry-based science engages students' minds as these students:
Answer: * investigate questions.

⫸ Kilogram Answer: mass (kg)
, ⫸ Ampere Answer: Electric current
⫸ Meter Answer: Length
⫸ Mole Answer: Amount of substance
⫸ Candela Answer: Luminous intensity
⫸ Kelvin Answer: SI unit for temperature
⫸ Second Answer: Time
⫸ Match the step in a scientific investigation with its definition.
Answer: Make an observation - The students will use their five
senses to make their observations.
Conclusion - Students will use the collected data and evidence to form
conclusions and answer questions.
Generate Question- Students will generate/create questions, make
hypotheses, make predictions, and plan investigations.
Investigate- Students will complete investigations, carry out
experiments, and conduct research and additional experiments, while
they gather data/collect evidence
