Three types of variablesThree types of variables
Manipulated: The thing you change Manipulated: The thing you change on purposeon purpose
Responding: The thing you hope is Responding: The thing you hope is going to change, and you are going to change, and you are measuring it.measuring it.
Controlled: The things you keep the Controlled: The things you keep the same (AKA everything else in the same (AKA everything else in the experiment)experiment)

Title:Title:
Weight of a Paper Airplane Weight of a Paper Airplane and and
How Far a Paper Airplane How Far a Paper Airplane FliesFlies
Research Question:Research Question:
How does the weight of a How does the weight of a paper airplane affect how far paper airplane affect how far the paper airplane flies?the paper airplane flies?
Variables:Variables:MV: weight of the paper airplaneMV: weight of the paper airplaneRV: how far the paper airplane fliesRV: how far the paper airplane fliesCV: airplane design, type of paper, CV: airplane design, type of paper,
same place same place
HypothesisHypothesis
If the weight of the paper If the weight of the paper airplane increases, then how airplane increases, then how far a paper airplane flies will far a paper airplane flies will decrease, because heavier decrease, because heavier objects won’t fly as far as objects won’t fly as far as lighter objects.lighter objects.
