Which term describes a statement that is always true under certain conditions in nature?

• Hypothesis

• Scientific Law

• Empirical Evidence

• Observation

Answer explanation

A Scientific Law is a statement that describes a consistent and universal relationship observed in nature, making it always true under specific conditions. This distinguishes it from hypotheses and observations.

What is a well-supported explanation of how or why something happens in nature, based on many observations and experiments?

• Scientific Theory

• Data

• Repetition

• Replication

Answer explanation

A scientific theory is a well-supported explanation of natural phenomena, derived from extensive observations and experiments. It provides a framework for understanding how and why things occur in nature.

What is an organized procedure to study something under controlled conditions called?

• Observation

• Experiment

• Scientific Model

• Repetition

Answer explanation

An organized procedure to study something under controlled conditions is called an experiment. It allows researchers to test hypotheses and observe outcomes systematically, distinguishing it from mere observation or repetition.

Using your senses to gather information is known as what?

• Data

• Observation

• Hypothesis

• Replication

Answer explanation

Using your senses to gather information is called observation. It involves noticing details through sight, sound, touch, taste, and smell, which is essential for collecting data in scientific inquiry.

What is a testable statement or prediction that can be investigated through experiments or observations?

• Scientific Law

• Hypothesis

• Independent Variable

• Dependent Variable

Answer explanation

A hypothesis is a testable statement or prediction that can be investigated through experiments or observations, making it the correct choice. Scientific laws describe established facts, while independent and dependent variables are components of experiments.

What is the factor that is changed on purpose in an experiment called?

• Dependent Variable

• Controlled Variable

• Independent Variable

• Data

Answer explanation

The factor that is changed on purpose in an experiment is called the Independent Variable. It is manipulated to observe its effect on the Dependent Variable, which is measured in the experiment.

What is the factor that changes as a result of the independent variable in an experiment?

• Independent Variable

• Dependent Variable

• Controlled Variable

• Scientific Model

Answer explanation

The dependent variable is the factor that changes in response to the independent variable in an experiment. It is what you measure to see the effect of the independent variable.

What is the term for information gathered through observations or experiments that can be recorded and analyzed?

• Data

• Repetition

• Replication

• Hypothesis

Answer explanation

The term 'Data' refers to information collected through observations or experiments, which can be recorded and analyzed. It is essential for drawing conclusions in scientific research.
