Classwork on Identifying Independent and Dependent Variables

Front

What is an independent variable?

Back

An independent variable is the factor that is changed or controlled in an 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

In an experiment, if you change the amount of sunlight a plant receives, what is the independent variable?

Back

The amount of sunlight.

Front

In an experiment measuring how temperature affects the rate of a chemical reaction, what is the dependent variable?

Back

The rate of the chemical reaction.

Front

What is the relationship between independent and dependent variables?

Back

The independent variable is manipulated to observe its effect on the dependent variable.

Front

If you are testing how different fertilizers affect plant growth, what is the dependent variable?

Back

The growth of the plants.

Front

In the equation y = mx + b, what does y represent?

Back

y represents the dependent variable.

Front

If you are studying how the height of a ramp affects the distance a ball rolls, what is the independent variable?

Back

The height of the ramp.

Front

What is a controlled variable?

Back

A controlled variable is a factor that is kept constant throughout an experiment to ensure that the results are valid.

Front

Why is it important to identify independent and dependent variables in an experiment?

Back

Identifying these variables helps to clarify the purpose of the experiment and ensures accurate data collection.
