Which of the following best describes a fair test in an experiment?

• Changing multiple variables at once

• Keeping all variables constant

• Changing only one variable while keeping others constant

• Not measuring any variables

How can you create a 'fair test'?

• By changing one factor and keeping all the other conditions constant

• By changing some variables but keeping one constant

• But repeating the experiment more than 10 times

• By allowing each scientist to record the results separately

Which investigation provides a fair test to determine which paper airplane travels the farthest?

• Make three different paper airplanes. Let each member of the team toss the paper airplane he/she created. Measure the distance each plane travels

• Make three paper airplanes from the same materials. Fold each paper the same way. Test each plane and measure the distance each plane travels.

• Make three different paper airplanes. Have one member of the group stand in a designated spot and toss each plane with the same amount of force. Measure the distance each plane travels.

• Make three paper airplanes from the same materials. Fold each paper the same way. Take turns tossing each plane with different amounts of force. Measure the distance each plane travels.

These are the variables that should stay the same. They do not get any changes in order to make for a fair test.

• Dependent Variables

• Controlled variables

• Independent Variables

In an experiment, why is it important to have a control group?

• To have more variables to measure

• To have a basis for comparison

• To change the outcome of the experiment

• To increase the number of independent variables
