What is a hypothesis?

Back

A hypothesis is a testable statement or prediction about the relationship between two or more variables. For example, 'If plants are given more sunlight, then they will grow taller.'

Front

What is an inference?

What is the independent variable in an experiment?

The independent variable is the factor that is intentionally changed or manipulated in an experiment. For example, in a study on music and test scores, the type of music is the independent variable.

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in response to changes in the independent variable. For example, test scores are the dependent variable in a study on music and studying.

Front

What is the scientific method?

Back

The scientific method is a systematic process of problem-solving that involves making a hypothesis and testing it through investigation.

Front

What is a control variable?

Back

A control variable is a factor that is kept constant throughout an experiment to ensure that the results are due to the independent variable.

Front

What is a constant in an experiment?

Back

A constant is a factor that does not change during an experiment, ensuring that the test conditions remain the same.

Front

What is an observation?

Back

An observation is the act of noticing and describing events or processes in a careful, orderly way.

Front

What is the difference between an observation and an inference?

Back

An observation is based on direct evidence, while an inference is a conclusion drawn from observations.

Front

What is a variable in scientific experiments?

Back

A variable is any factor, trait, or condition that can exist in differing amounts or types in an experiment.
