Variables and Constants in Experiments

The video tutorial explains the concepts of variables and constants in experiments. It uses a paper ball experiment to demonstrate how constants remain unchanged while a variable is altered. The experiment involves throwing two paper balls, one with tape and one without, to observe the effect of the variable (tape) on the distance traveled. The tutorial emphasizes the importance of maintaining constants to ensure accurate results and concludes with a review of the experiment's findings.

What is a constant in the context of an experiment?

• A factor that is irrelevant

• A factor that is unpredictable

• A factor that changes

• A factor that remains the same

Why is it important to have only one variable in an experiment?

• To make the experiment more complex

• To ensure that the results are due to one factor

• To confuse the participants

• To save time

In the paper ball experiment, what was the constant?

• The type of tape used

• The number of throws

• The size and material of the paper

• The distance thrown

What was the variable in the paper ball experiment?

• The hallway used

• The throwing arm

• The presence of tape on the paper ball

• The size of the paper

How did the presence of tape affect the paper ball's performance?

• It allowed the ball to travel further

• It made the ball fly in a curve

• It made no difference

• It made the ball lighter

What was the purpose of using the same starting spot and arm in the experiment?

• To save time

• To confuse the participants

• To make the experiment more challenging

• To ensure consistency in the experiment

Why was the air not considered a factor in the experiment?

• Because it was windy

• Because the experiment was conducted indoors

• Because the air was measured

• Because it was irrelevant

What conclusion can be drawn from the paper ball experiment?

• The experiment was inconclusive

• The taped ball traveled further due to increased mass

• The paper balls were too light

• The tape made no difference

What is the main takeaway about variables from the experiment?

• Variables should be changed frequently

• Variables are irrelevant

• Variables should be kept constant

• Only one variable should be changed to see its effect

What role did the constants play in the experiment?

• They ensured that the results were due to the variable

• They were the main focus

• They were ignored

• They were changed frequently
