Identifying variables in a controlled experiment

An experiment in which you change only one variable is called a

• controlled experiment

• proper experiment

• improper experiment

In the Air Trolley Experiment: The number of winds was the

• dependent variable

• constant variable

• independent variable

In the Air Trolley Experiment, the distance it traveled was the

• independent variable

• dependent variable

• constant variable

The variables you need to keep the same in a controlled experiment are called

• dependent variables

• independent variables

• constant variables

Some people call the constant variables the control variables

• true

• false

There are controlled experiments where you set up the experiment without making the change, for example ...you might just use the same number of winds all of the time in an air trolley just to see if it increases its distance normally without increasing the winds....this is called the

• control

• bomb

• end all

How can you make your experiment more valid?

• Do it once

• Do it twice

• Do it multiple times , we call this trials

Using the same fishing line, using the same winding technique, etc are all examples of

• independent variables

• dependent variables

• constant variables

• kinetic energy

• potential energy

• nuclear energy
