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.
