,Covers: NYSTCE CST Multi-Subject Part 3 (245), Scientific Inquiry, Physical Sciences, Life
Sciences, Earth & Space Sciences, and Arts & Sciences
SECTION 1: SCIENTIFIC INQUIRY & PROCESS (Questions 1-20)
1. Which of the following is the first step in the scientific method?
A) Formulate a hypothesis
B) Conduct an experiment
C) Make an observation
D) Draw a conclusion
Answer: C) Make an observation
Explanation: The scientific method begins with making observations, which leads to asking
questions and formulating hypotheses. Data collection and analysis follow, leading to
conclusions .
2. A scientist is investigating the effect of fertilizer on plant growth. Which of the
following is the independent variable in this experiment?
A) Plant height
B) Amount of fertilizer
C) Amount of water
D) Type of soil
Answer: B) Amount of fertilizer
Explanation: The independent variable is the factor that is manipulated or changed by the
,experimenter—in this case, the amount of fertilizer. Plant height is the dependent variable
being measured .
3. A scientist is studying the effect of temperature on the rate of a chemical reaction.
Which of the following is the dependent variable?
A) Temperature
B) Rate of reaction
C) Catalyst used
D) pH of the solution
Answer: B) Rate of reaction
Explanation: The dependent variable is the factor that is measured or observed in response
to changes in the independent variable (temperature).
4. In a controlled experiment, which variable is kept constant to ensure a fair test?
A) Independent variable
B) Dependent variable
C) Control variable
D) Experimental variable
Answer: C) Control variable
Explanation: Control variables are factors that are kept the same throughout the experiment
to ensure that any observed effect is due to the independent variable .
, 5. Which of the following is NOT a characteristic of a valid scientific hypothesis?
A) It is testable
B) It is falsifiable
C) It is based on personal opinion
D) It is based on prior knowledge
Answer: C) It is based on personal opinion
Explanation: A valid hypothesis must be testable and falsifiable and based on prior
knowledge or observation. Personal opinion alone does not constitute a scientific
hypothesis .
6. A graph showing the relationship between time and distance traveled by a car is an
example of which type of graph?
A) Bar graph
B) Pie chart
C) Line graph
D) Scatter plot
Answer: C) Line graph
Explanation: Line graphs are used to show trends over time or continuous data, such as
distance traveled versus time .
