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 in an experiment. It is affected by changes in the independent variable.

Front

Why is it important to control variables in an experiment?

Back

Controlling variables is important to ensure that any changes in the dependent variable are due to the independent variable, allowing for accurate conclusions.

Front

What is a controlled experiment?

Back

A controlled experiment is a test where only one variable is changed at a time while all other variables are kept constant.

Front

What is the purpose of a hypothesis in an experiment?

Back

A hypothesis is a testable prediction about the relationship between the independent and dependent variables.

Front

What is the role of observation in scientific experiments?

Back

Observation is used to gather data and evidence during an experiment, which helps in analyzing the results.

Front

What does it mean to measure growth in plants?

Back

Measuring growth in plants typically involves tracking changes in height, number of leaves, or overall health over time.

Front

What is the significance of using the same type of plant in an experiment?

Back

Using the same type of plant ensures that the results are not influenced by genetic differences, allowing for a fair test.

Front

What is a variable in scientific terms?

Back

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

Front

What is the difference between qualitative and quantitative data?

Back

Qualitative data describes characteristics or qualities (e.g., color, texture), while quantitative data involves numerical measurements (e.g., height, weight).
