Independent and Dependent Variables

Front

What is the independent variable in David's plant growth experiment?

Back

The amount of sunlight that David manipulates or controls.

Front

In an experiment conducted by Henry, James, and Avery, what is considered a dependent variable?

Back

A dependent variable is the variable being measured or observed by Henry, James, and Avery in their experiment.

Front

In a science fair, Aiden is conducting an experiment. Which variable is Aiden manipulating or changing in his experiment?

Back

independent variable

Front

In a science fair experiment, what variable are Mia and Ava measuring or observing?

Back

the growth of the plant (dependent variable)

Front

What is the purpose of the amount of sunlight (an independent variable) in Priya's experiment?

Back

To observe its effect on the growth of the plants (the dependent variable).

Front

Example of a dependent variable in a physics experiment where a ball is dropped from different heights.

Back

The time it takes for the ball to fall to the ground.

Front

In a science experiment, Elijah is studying the effect of different amounts of sunlight on the growth of a plant. How are the amount of sunlight (independent variable) and the growth of the plant (dependent variable) related in Elijah's experiment?

Back

The amount of sunlight (independent variable) is manipulated by Elijah, while the growth of the plant (dependent variable) is measured or observed and is affected by the amount of sunlight.

Front

What is the role of the control group in Abigail's experiment on the effect of different types of soil on plant growth?

Back

To provide a standard for comparison, such as plants grown in normal soil.

Front

What would be a control variable in Elijah's experiment on the effect of different types of soil on plant growth?

Back

A variable that remains constant and unchanged throughout the course of the experiment, like the amount of sunlight each plant receives.

Front

What happens if Ethan does not properly control the independent variable in their experiment?

Back

The results of their experiment may not be valid.
