Rebecca wondered if the type of papre used to make a paper airplane would affect the distance the plane flew.She hypothesized that an airplane made of light weight paper would fly farther than an airplane made of heavier paper.Rebecca made 5 airplanes.They were all exactly the same except for the weight of the paper from which they were made.She performed 5 trials,throwing each plane 5 times in the same conditions.She measured the distance each plane traveled each time and recorded the measurements.Rebecca graphed the measurements.She analyzed the graph and decided that the airplane made of light paper flew farther than the ones made of heavier paper.
