Day 78: 8.PFA.3 - Independent and Dependent Variables

Front

What is an independent variable?

Back

An independent variable is the variable 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 variable that is measured and affected in an experiment, depending on the independent variable.

Front

In the formula V = 4πr³, what does V represent?

Back

V represents the volume of the sphere.

Front

In the formula V = 4πr³, what does r represent?

Back

r represents the radius of the sphere.

Front

If the radius of a sphere increases, what happens to its volume?

Back

The volume increases, as it is directly related to the cube of the radius.

Front

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

Back

The amount of sunlight is the independent variable.

Front

In an experiment, if you measure the growth of a plant based on sunlight exposure, what is the dependent variable?

Back

The growth of the plant is the dependent variable.

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

In the context of a graph, what does the y-axis typically represent?

Back

The y-axis typically represents the dependent variable.

Front

In the context of a graph, what does the x-axis typically represent?

Back

The x-axis typically represents the independent variable.
