First Semester Test Review--Part 1

Front

What is an independent variable?

Back

An independent variable is the factor that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

What is a dependent variable?

Back

A dependent variable is the factor that is measured or observed in an experiment, which is affected by changes in the independent variable.

Front

What is a constant in an experiment?

Back

A constant is a factor that remains the same throughout an experiment to ensure that the test results are valid.

Front

What is the scientific method?

Back

The scientific method is a systematic process used for scientific investigation, including steps like stating a problem, forming a hypothesis, conducting experiments, and analyzing data.

Front

What is a hypothesis?

Back

A hypothesis is a testable prediction about the relationship between two or more variables.

Front

What does it mean to perform an experiment?

Back

Performing an experiment involves conducting tests to gather data and observe the effects of changing the independent variable.

Front

What is the purpose of recording and analyzing data?

Back

Recording and analyzing data helps scientists understand the results of their experiments and draw conclusions.

Front

What is an observation in science?

Back

An observation is the act of noting and recording something using the senses or scientific instruments.

Front

How does changing the independent variable affect the dependent variable?

Back

Changing the independent variable can lead to changes in the dependent variable, which is what the experiment aims to measure.

Front

What is the role of a control group in an experiment?

Back

A control group is used as a standard for comparison in an experiment, where the independent variable is not applied.
